Top-side Cooling Simplifies Design and Reduces Cost for Compact Power Solutions
onsemi, a leader in intelligent power and sensing technologies, announced a series of new MOSFET devices that feature innovative top-side cooling to assist designers in challenging automotive applications, especially within motor control and DC/DC conversion. The company is showing the new devices at its booth 101 in hall C4 at electronica, the world’s leading trade fair and conference for electronics.
Housed in a TCPAK57 package measuring just 5mm x 7mm, the new Top Cool devices feature a 16.5mm2 thermal pad on the top side. This allows heat to be dissipated directly into a heatsink rather than via a typical printed circuit board (PCB). By enabling the use of both sides of the PCB and decreasing the amount of heat going into it, the TCPAK57 provides increased power density. Improved reliability of the new design adds to an overall extended system lifetime.
“Cooling is one of the greatest challenges in high power design and successfully addressing it is the key enabler to reducing size and weight, which is critical in modern automotive design,” said Fabio Necco, vice president and general manager, Automotive Power Solutions at onsemi. “With excellent electrical efficiency and having eliminated the PCB from the thermal path, the design is significantly simplified while reducing size and cost.”
The devices deliver the electrical efficiency required in high power applications with RDS(ON) values as low as 1mΩ. Additionally, the gate charge (Qg) is low (65 nC), reducing losses in high-speed switching applications.
This solution leverages onsemi’s deep expertise in packaging to provide the highest power density solution in the industry. TCPAK57 initial portfolio includes 40V, 60V and 80V. All devices are capable of operating at junction temperatures (Tj) of 175°C and are AEC-Q101 qualified and PPAP capable. This, along with their gull wings that allows inspection of solder joints and superior board level reliability, makes them ideally suited to demanding automotive applications. The target applications are high/medium power motor controls such as electric power steering and oil pumps.

onsemi Silicon Carbide Technology Enables All-Electric VISION EQXX to Go Further on a Single Charge
onsemi, a leader in intelligent power and sensing technologies, announced that Mercedes-Benz adopted onsemi silicon carbide (SiC) technology for traction inverters as part of a strategic collaboration. onsemi’s VE-Trac SiC modules increase the efficiency and lower the weight of the all-electric Mercedes-Benz VISION EQXX’s traction inverter, extending the electric vehicle’s (EV’s) range by up to 10%. The EV completed a 1,202 km (747 mile) trip from Stuttgart, Germany to Silverstone, England, holding the record for longest distance traveled on a single charge.
The VISION EQXX sets new standards for electric range and efficiency, while remaining sustainable and luxurious – and consuming less than 10 kWh of energy per 100 km (62 miles). This was achieved by a benchmark drag coefficient of just 0.17, lightweight design, reduced rolling resistance and the use of a battery that stores 100 kWh in 50% less space (and with 30% less weight) than comparable batteries. Key to the unprecedented range is an electrical system that ensures that 95% of the energy stored in the traction battery reaches the wheels – a huge improvement over internal combustion engine (ICE) vehicles that are only able to achieve around 30%.

The Transistor of 2047: Expert Predictions. What will the Device be Like on Its 100th Anniversary?
The 100th anniversary of the invention of the transistor will happen in 2047. What will transistors be like then? Will they even be the critical computing element they are today? IEEE Spectrum asked experts from around the world for their predictions.
- What will transistors be like in 2047?
Expect transistors to be even more varied than they are now, says one expert. Just as processors have evolved from CPUs to include GPUs, network processors, AI accelerators, and other specialized computing chips, transistors will evolve to fit a variety of purposes. “Device technology will become application domain–specific in the same way that computing architecture has become application domain–specific,” says H.-S. Philip Wong, an IEEE Fellow, professor of electrical engineering at Stanford University, and former vice president of corporate research at TSMC.
Despite the variety, the fundamental operating principle—the field effect that switches transistors on and off—will likely remain the same, suggests Suman Datta, an IEEE Fellow, professor of electrical and computer at Georgia Tech, and director of the multi-university nanotech research center ASCENT. This device will likely have minimum critical dimensions of 1 nanometer or less, enabling device densities of 10 trillion per square centimeter, says Tsu-Jae King Liu, an IEEE Fellow, dean of the college of engineering at the University of California, Berkeley, and a member of Intel’s board of directors.
“It is safe to assume that the transistor or switch architectures of 2047 have already been demonstrated on a lab scale”—Sri Samavedam
Experts seem to agree that the transistor of 2047 will need new materials and probably a stacked or 3D architecture, expanding on the planned complementary field-effect transistor (CFET, or 3D-stacked CMOS). [For more on the CFET, see “Taking Moore’s Law to New Heights.”] And the transistor channel, which now runs parallel to the plane of the silicon, may need to become vertical in order to continue to increase in density, says Datta.
AMD senior fellow Richard Schultz, suggests that the main aim in developing these new devices will be power. “The focus will be on reducing power and the need for advanced cooling solutions,” he says. “Significant focus on devices that work at lower voltages is required.”
- Will transistors still be the heart of most computing in 25 years?
It’s hard to imagine a world where computing is not done with transistors, but, of course, vacuum tubes were once the digital switch of choice. Startup funding for quantum computing, which does not directly rely on transistors, reached US $1.4 billion in 2021, according to McKinsey & Co.
But advances in quantum computing won’t happen fast enough to challenge the transistor by 2047, experts in electron devices say. “Transistors will remain the most important computing element,” says Sayeef Salahuddin, an IEEE Fellow and professor of electrical engineering and computer science at the University of California, Berkeley. “Currently, even with an ideal quantum computer, the potential areas of application seem to be rather limited compared to classical computers.”
Sri Samavedam, senior vice president of CMOS technologies at the European chip R&D center Imec, agrees. “Transistors will still be very important computing elements for a majority of the general-purpose compute applications,” says Samavedam. “One cannot ignore the efficiencies realized from decades of continuous optimization of transistors.”
- Has the transistor of 2047 already been invented?
Twenty-five years is a long time, but in the world of semiconductor R&D, it’s not that long. “In this industry, it usually takes about 20 years from [demonstrating a concept] to introduction into manufacturing,” says Samavedam. “It is safe to assume that the transistor or switch architectures of 2047 have already been demonstrated on a lab scale” even if the materials involved won’t be exactly the same. King Liu, who demonstrated the modern FinFET about 25 years ago with colleagues at Berkeley, agrees.
But the idea that the transistor of 2047 is already sitting in a lab somewhere isn’t universally shared. Salahuddin, for one, doesn’t think it’s been invented yet. “But just like the FinFET in the 1990s, it is possible to make a reasonable prediction for the geometric structure” of future transistors, he says.
AMD’s Schultz says you can glimpse this structure in proposed 3D-stacked devices made of 2D semiconductors or carbon-based semiconductors. “Device materials that have not yet been invented could also be in scope in this time frame,” he adds.
- Will silicon still be the active part of most transistors in 2047?
Experts say that the heart of most devices, the transistor channel region, will still be silicon, or possibly silicon-germanium—which is already making inroads—or germanium. But in 2047 many chips may use semiconductors that are considered exotic today. These could include oxide semiconductors like indium gallium zinc oxide; 2D semiconductors, such as the metal dichalcogenide tungsten disulfide; and one-dimensional semiconductors, such as carbon nanotubes. Or even “others yet to be invented,” says Imec’s Samavedam.
“Transistors will remain the most important computing element”—Sayeef Salahuddin
Silicon-based chips may be integrated in the same package with chips that rely on newer materials, just as processor makers are today integrating chips using different silicon manufacturing technologies into the same package, notes IEEE Fellow Gabriel Loh, a senior fellow at AMD.
Which semiconductor material is at the heart of the device may not even be the central issue in 2047. “The choice of channel material will essentially be dictated by which material is the most compatible with many other materials that form other parts of the device,” says Salahuddin. And we know a lot about integrating materials with silicon.
- In 2047, where will transistors be common where they are not found today?
Everywhere. No, seriously. Experts really do expect some amount of intelligence and sensing to creep into every aspect of our lives. That means devices will be attached to our bodies and implanted inside them; embedded in all kinds of infrastructure, including roads, walls, and houses; woven into our clothing; stuck to our food; swaying in the breeze in grain fields; watching just about every step in every supply chain; and doing many other things in places nobody has thought of yet.
Transistors will be “everywhere that needs computation, command and control, communications, data collection, storage and analysis, intelligence, sensing and actuation, interaction with humans, or an entrance portal to the virtual and mixed reality world,” sums up Stanford’s Wong.

Energy-Saving Technology and Carbon Neutrality on High-Speed Railways
Railways are more energy-efficient than other modes of passenger transportation, with CO₂ emissions per ton-kilometer roughly one-seventh those of passenger cars. The difference is more pronounced over long distances, and high-speed railway networks contribute substantially to energy savings in transport infrastructure.
Although high-speed railway networks have long been part of the transport infrastructure of developed countries, developing countries have also moved toward constructing them in recent years. However, countries that have already put high-speed railway networks into practical use and have the corresponding technology are exploring public and private channels for marketing the infrastructure and technology to countries looking to establish networks. The infrastructure and technology must deliver high speeds, low noise, and safety as well as eco-friendly performance through reduced CO₂ emissions now that the focus includes achieving carbon neutrality.
Eco-friendliness and electronics technology of rolling stock
Although railways are eco-friendlier than other modes of transport, they still consume a lot of electricity and fuel. Specifically, the worldwide proliferation of high-speed railway networks has increased CO₂ emissions, hampering efforts to achieving carbon neutrality. Therefore, further energy conservation is needed.
The key to improving the eco-friendliness of railways is energy-saving in drive systems. Three factors will contribute substantially to achieving this: energy-saving in actual drive systems, downsizing and reducing the weight of drive systems, and reducing the weight of rolling stock. Regarding the first two factors, developing converters and inverters with less power loss in drive systems is essential for reducing energy loads in rail transport and cutting CO₂ emissions. This development requires the adoption of high-performance semiconductor devices and low-loss capacitors and inverters.
Drive system power control technology
Of all the components of rolling stock, drive motors require the most power. To save energy in rolling stock, it is necessary to improve the efficiency of drive motors by limiting their electricity consumption. To achieve this, devices known as “inverters” are installed to efficiently control drive motors.
Presently, the power for most rolling stock is supplied via alternating current converted to direct current. The device that converts AC to DC is known as a “converter.” AC motors, air conditioning, lighting, and other equipment requiring AC power are equipped with inverters to convert DC to AC.
Inverters not only convert DC to AC, but can also control frequency and voltage, a capacity known as “inverter control.” Inverter control is widely utilized in air conditioners, microwave ovens, fluorescent lights, and other home electronics. The precision and efficiency of inverter control are major technological determinants of energy consumption in rolling stock, which requires large amounts of power.
Evolution of inverter control
Inverter control has been put to practical use on rolling stock since the 1980s. Originally, inverters worked using a method known as “pulse width modulation,” or PWM, in which output voltage is changed by converting DC voltage to block pulses through switching and varying the pulse width at regular intervals. Thyristors were used in some of the main circuit elements, but later, gate turn-off (GTO) thyristors became mainstream.
The mid-1990s saw the emergence of insulated-gate bipolar transistors (IGBTs), which offer lower losses and higher-frequency switching than GTO thyristors and thus drove increases in efficiency and voltage control. Additionally, intelligent power modules (IPM), which integrate IGBTs with drive and protection circuits, have improved performance, functionality, and reliability, and have been put into practical use as a technology to advance inverters.
Inverter control of drive motors in rolling stock
AC motors for rolling stock—electric motors that provide the driving force for trains—have become practical thanks to advances in power electronics technology, especially inverters. Using inverters results in substantial reductions in overall losses by providing better weight-to-output ratios than DC motors and eliminating losses from resistors employed in conventional rheostatic control. AC motors in use include synchronous motors and induction motors. Of the two, AC induction motors with variable voltage variable frequency (VVVF) inverter control systems are widely used for their excellent durability and user-friendliness. Additionally, with the introduction of IGBT and IPM, which contribute to higher withstand voltages and larger power supply capacities, and the use of three-level inverter systems, AC induction motors are becoming more economical, with less magnetic noise and fewer harmonics that cause electronic equipment to malfunction.
Required performance of electronic components of inverter control circuits
Presently, manufacturers are shifting from silicon (Si) to silicon carbide (SiC) and gallium nitride (GaN) as the materials for the semiconductor devices of inverters to achieve greater withstanding pressure and faster switching speeds. However, as switching speeds increase, the amount of heat generated also increases. Thus, the electronic components of each inverter circuit must also be highly heat-resistant.
Inverters comprise not only semiconductor devices, but also rectifier circuits; commutation circuits to operate thyristors; snubber circuits that suppress parasitic inductance, which causes ringing, and noise caused by surge voltage; and more. Capacitors, resistors, inductors, and other components are used in these circuits.
Low heat resistance of electronic components requires cooling equipment, and the lower the heat resistance of components, the larger and more complex the cooling equipment tends to be. Installing and expanding cooling equipment increases the weight of the rolling stock and causes excess electricity consumption.
Therefore, inverters must comprise heat-resistant electronic components to reduce rolling stock weight and electricity consumption. Inverters must also accommodate circuit board deflection, resist impulse voltage, and otherwise be reliable enough to function normally in demanding operating conditions.
Energy-saving technology and carbon neutrality on high-speed railways
Amid the ongoing construction of high-speed railways around the world, controversy surrounds the immense expense of some, particularly the high-speed rail project linking Los Angeles and San Francisco in the state of California in the United States (scheduled to open in 2033), which is expected to cost roughly 77.3 billion dollars, and the High Speed Two (HS2) project to connect major cities in the UK.
National governments are investing extensively in these projects because of the environmental benefits of rail transport over other modes of transport; the level of investment also illustrates how governments are looking to rail transport as a trump card for achieving carbon neutrality, which is considered to be difficult. The trend also applies to new railway networks in developing countries, where electronics technology will undoubtedly attract more and more attention for its ability to reduce CO₂ emissions through energy conservation.

Germany and Europe: Semiconductor Industry to Be Strengthened
The associations VDE and ZVEI are working hard to ensure that Germany and Europe increase their capacities for the production of microelectronics chips, as they stated at the Microelectronics for Future 2022 Summit in Berlin. The EU Chips Act, which the EU Commission presented at the end of 2021, plays a special role here.
“The EU Chips Act is highly significant because the microelectronics industry plays an essential role in Germany and Europe by supplying the user industries downstream in the supply chain,” said ZVEI President Dr. Gunther Kegel. However, Kegel said additional funding must be made available for the EU Chips Act projects. “We can only survive in international competition if we implement important European industrial projects with a high level of commitment,” Kegel emphasized in this context. The goal, he said, must be to substantially expand research, development and production through an active location policy and industrialization support. This also includes interpreting the concept of the EU Chips Act broadly so as not to bypass the needs of Europe’s key industries, he said. “What is necessary is that the Chips Act takes into account all technologies and structural sizes of chips,” Kegel said.
With well over 50 % of Europe’s microelectronics production, Germany plays a leading role and must face up to its responsibilities. VDE President Dr. Armin Schnettler: “The demand for microelectronics will continue to rise due to the megatrends of electrification, digitalization and the energy transition.” Locational disadvantages in the areas of settlement and operating costs, competition law and taxation would have to be eliminated. At the same time, a funding system must be established that makes and implements decisions quickly at regional, national and European level, Schnettler adds: “Europe needs non-discriminatory and crisis-proof access to global microelectronics solutions in order to remain technologically sovereign.”
There is also a special focus on the issue of young talent. The VDE estimates that more than 19,000 new electrical engineers are needed each year. Schnettler points out that instead, the number of first-year students fell by another good four percent last year: “We need to do a better job of communicating to the younger generation that careers in electrical engineering and information technology have a lot to offer. These are not just secure, well-paid jobs with a future. We are actively helping to ensure that this world remains a world worth living in.”

Gallium Nitride: Powering the Vehicles of the Future
Founded in 2010 and headquartered in Israel, VisIC Technologies was launched with the goal of advancing Gallium Nitride (GaN) technology into mainstream use. After its initial team of GaN pioneers made several ground-breaking developments in device design, the company focused on applying such technologies to the automotive industry.
VisIC’s team steadily grew, and development of robust transistor devices based on GaN technology began. The team arrived at an optimized design of one of the most reliable, high voltage, high current (650V, up to 200A per die) transistors. The unique D3GaN (Direct Drive D-mode) power switch technology for electric vehicles (EVs) is designed to enable use of smaller, lighter, and cheaper batteries and to provide the car with a more extended range.
Overall, the company seeks to make the function of driving better, with a focus on high-performance, noise reduction, affordability, and pollution reduction. To support the affordability of EVs, VisIC Technologies works to keep manufacturing costs as low as possible and make the vehicle’s powertrain more efficient.
VisIC has produced the first GaN-based transistors to be used in automotive traction inverters and is now in the development and evaluation phase with several original equipment manufacturers (OEMs) and Tier 1 customers for series production.
In conversation with The Innovation Platform, Dr Tamara Baksht, Co-founder and CEO of VisIC Technologies, discusses the benefits of GaN and explains more about the company’s achievements so far and its future plans.
- Can you explain the background of VisIC Technologies, your key product offering, and your main goals and objectives?
Using GaN, VisIC Technologies is working to bring to the market high efficiency electronic components, namely power switches, for the energy and transportation sectors. I think it is important to address the evolution of Gallium Nitride (GaN). We have seen this technology transition to be scalable and affordable. Light-emitting diodes (LEDs) are a good example of how a new material or technology can transform an entire industry. Today, all white and blue LEDs are made with GaN. GaN gives a blue light and, in order to make white light, you need red, green, and blue (RGB). For years, there had been green and red but blue had been missing, meaning that it was impossible to make true white LEDs. Since the implementation of GaN, the whole lighting industry has changed.
The value of GaN is that for the same level of power as silicon, it provides much higher efficiency or a much smaller form factor. Normally, these three parameters – power level, form factor, and efficiency – are in trade off. However, GaN brings the solution to this trade-off.
When I started this company, most GaN transistors had been mainly developed for communication applications. In terms of industry, electrical energy conversion had been relatively low-tech, and the importance of electrical energy had not been obvious. Today, the fact that electrical energy became the bottleneck of our world has been recognized. A significant part of energy is lost in conversion between voltages. In a world where the scarcity of electricity is becoming ever more apparent, working to improve the overall efficiency of this transfer and conversion is critical.
A Gallium Nitride high electron mobility transistor (HEMT) was successfully used as a power amplifier when the company first began. We therefore knew that significant effort would be required to make it usable for power conversion and to develop good power switches. After several years of focused development effort, the first working prototypes had been successfully tested by industry partners. After analyzing results and exploring the market, we chose to focus our work on the fastest growing segment: electric transportation. It is remarkable that, for the first time in the semiconductor industry, electric vehicle semiconductors impact the core values of a car – manufacturing cost, driving distance, power, and acceleration. In electric cars, semiconductor power switches are responsible for conversion of electrical energy from battery to car motion. The new level of power-size-efficiency trade-off is important because electric cars must have high power and, as space is limited, batteries must also be compact. Efficiency is critical because of the cost of the battery; so, a high efficiency inverter means we can use less battery, making the car cheaper. Moreover, we can use the same battery and have much longer driving distances, offering better value for the customer.
- What role has innovation played in accelerating your company and GaN technology?
Making our product a mass market technology requires significant innovation as we are facing a combination of challenges.
Firstly, we are a deep-technology semiconductor start-up company, which is a lengthy and capital-intensive process. We then have the added challenge of breaking into the automotive market, which also takes a long time, comes with high liability and is known to be very conservative. However, at the same time, this direction is great for us as it is where there is the highest need for high-efficiency, high-power semiconductors. The process can be counterintuitive, but I think we are succeeding because we have very good access to funds, we have been oversubscribed in the last couple of rounds, and we have got very good results from professionals in our sector with a much lower total investment compared to our competitors.
We are not only innovating with the technology, but it is also essential that we are innovative across the company as a whole and in our organizational structure.
- What makes your product offering and company different?
Our advantage is that GaN transistors have significantly better efficiency than silicon transistors. Another advantage of GaN against over emerging technologies that are slightly more mature, such as silicon carbide, is the manufacturing cost. GaN is a brownfield manufacturing process, meaning we are reusing standard silicon factories.
I believe that we make the best GaN product for automotive purposes. Whilst other companies produce very good GaN for applications such as chargers and telephone communications, our devoted focus on the automotive sector has resulted in the best offering available.
As a company, we are truly global, and we started to work remotely long before the pandemic. I believe that the right people are more important than their location. To make such a complex product and business possible, we need brilliant people. We therefore hired employees from across the globe, not because we need localization but because we need brilliant minds.
- What research and development processes are behind your product?
Our product is a very complex combination of a few powerful technologies. To make a good product in this area, you need a solid combination of a good semiconductor, good packaging, and good electronic design. We must find the right balance in all these areas to create the best possible product. To achieve this, we have a dedicated semiconductor department, a power and electronics department, and a packaging department.
Our R&D work is done collaboratively and iteratively with Tier 1 customers, who adapt to the new technology and integrate the new components in their next-generation systems. Changes on their part influence our component.
- What’s next for VisIC Technologies?
We are currently working to establish a reliable supply chain for the developed product and production is scheduled for the upcoming years. This will be the main direction of our work for the near future.
I am quite confident that, as Gallium Nitride gets more mature and is produced at a higher volume, it will replace most silicon switches in power applications. I am confident that, in 2030, the best electric cars in all categories will have GaN devices inside.
