UnitedSiC Announced Industry-Best 6mohm SiC FET

UnitedSiC, a leading manufacturer of silicon carbide (SiC) power semiconductors, has responded to the power designer’s requests for higher-performance, higher-efficient SiC FETs with the announcement of the industry’s best 750V, 6mohm device. At a RDS(on) value of less than half the nearest SiC MOSFET competitor, the new 6mohm device also provides a robust short-circuit withstand time rating of 5ms. There are 9 new device/package options in the 750V SiC FET series, rated at 6, 9, 11, 23, 33, and 44mohms.  All devices are available in the TO-247-4L package while the 18, 23, 33, 44, and 60mohm devices also come in the TO-247-3L. Complemented by the already available 18 and 60mohm devices, this 750V expanded series provides designers with more device options, enabling more design flexibility to achieve an optimum cost/efficiency trade-off while maintaining generous design margins and circuit robustness.

UnitedSiC SiC FET

Gen 4 SiC FETs from UnitedSiC are a ‘cascode’ of a SiC JFET and a co-packaged silicon MOSFET. These together provide the full advantages of wide band-gap technology – high speed and low losses with high temperature operation, while retaining an easy, stable, and robust gate drive with integral ESD protection. The advantages are quantified by Figures of Merit (FoMs) such as RDS(on) x A, a measure of conduction losses per unit die area. Gen 4 SiC FETs achieve the lowest values in the market at both high and low die temperatures. FoM RDS(on) x EOSS/QOSS is important in hard-switching applications and is half the nearest competitor value. FoM RDS(on) x COSS(tr) is critical in soft-switching applications and UnitedSiC device values are around 30% less than competitor parts, rated at 650V compared with UnitedSiC’s at 750V. For hard switching applications, the integral body diode of SiC FETs is superior in recovery speed and forward voltage drop to competing Si MOSFET or SiC MOSFET technologies. Other advantages incorporated into the Gen 4 technology are reduced thermal resistance from die to case by advanced wafer thinning techniques and silver-sinter die-attach. These features enable maximum power output for low die temperature rise in demanding applications.

With their latest improvements in switching efficiency and on-resistance, the new UnitedSiC SiC FETs are ideal for challenging, emerging applications. These include traction drives and on- and off-board chargers in electric vehicles and all stages of uni- and bi-directional power conversion in renewable energy inverters, power factor correction, telecoms converters and AC/DC or DC/DC power conversion generally. Established applications also benefit from use of the devices for an easy boost in efficiency with their backwards compatibility with Si MOSFET and IGBT gate drives and established TO-247 packaging.

GaN Systems Signed Semiconductor Capacity Agreement with BMW

GaN Systems, the global leader in GaN power semiconductors, announced the signing of a comprehensive Capacity Agreement with BMW Group for GaN Systems’ high-performance, automotive-grade GaN power transistors, which increase the efficiency and power density of critical applications in electric vehicles.

GaN power semiconductors are a key ingredient to achieve the small size, lightweight, and high efficiency required in the next generation of high-performance electric vehicles.  Under the terms of the agreement, GaN Systems will provide capacity for multiple applications in series production. The guaranteed volumes by GaN Systems are a key building block for reliability in the supply chain for automotive players like BMW.

BMW’s relationship with GaN Systems began more than four years ago when BMW’s engineers found that small size, lightweight, low-cost onboard chargers, DC/DC converters, and traction inverters were enabled by GaN. This led to investment from BMW’s venture capital firm, BMW I Ventures, to support and accelerate the automotive qualification of the GaN technology.

“The close collaboration among GaN Systems and BMW’s engineers has helped to solidify the technology for automotive series production, resulting in the most advanced GaN power transistors in the marketplace today,” said Kasper Sage, managing partner BMW i Ventures.  “As electric vehicles become more prominent, the demand for critical semiconductor components is only going to increase, thereby making strategic partnerships with suppliers like GaN Systems even more important.”

Silicon MOSFET Market and Technology Trends 2021

Silicon MOSFETs are key components in a very wide range of low and mid-power applications. In 2020, the silicon MOSFET market was worth $7.5B. Yole Développement expects a 3.8% Compound Annual Growth Rate (CAGR) from 2020-2026, with most revenue coming from consumer and automotive markets. In general, 2021 has been an impressive year for MOSFETs with a huge recovery from COVID thanks to the high demand for computing and consumer electronics.

MOSFET Market Yole

Today the consumer market contributes 37% of silicon MOSFET revenues, making it the largest sector. Yole Développement expects this to fall in coming years due to lower end system demand after COVID-19 lockdowns, which have been very good for computing and consumer electronics, resulting in a $2.8B market by 2020. Automotive, including Electric Vehicles (EV), will boost the demand for silicon power MOSFETs due to increasing adoption of auxiliary systems and electrification. Auxiliary motor drives boost low voltage MOSFETs, while electrification boosts high voltage MOSFETs that are included in DC/DC converter or on-board charger systems. The two segments together are today 21% of the MOSFET market. They will increase to 32% by 2026.

Of course, MOSFETs play an important role in many any other applications. A detailed analysis of the silicon MOSFET market and technology trends by application can be found in the latest Yole Développement report.

As detailed in the report, China accounts for 38% of silicon MOSFET sales. As well as growing demand for silicon MOSFETs for different applications, the Chinese government is pushing for domestic manufacturing. It is therefore not surprising that Chinese players are investing in manufacturing capabilities.

Foundries like HHGrace and CanSemi have invested in 300mm facilities to cope with higher production of MOSFETs and other power components and have started production in them. However, this is not the end of Chinese push for 300mm. SiEn is building a 300mm fab, as well as CRMicro and Nexperia. In fact, CRMicro recently raised money through an Initial Public Offering (IPO), and has already expanded its 200mm line. Other companies like Jiejie Microelectronics and SMIC are following the same pattern. All of them want to invest the money raised into manufacturing capacity.

However, it is not all about investments in manufacturing sites. Chinese companies are also gaining market share via acquisitions. Deals by Chinese-owned companies are not straightforward since the China-US trade war started. See for example the Nexperia–Newport, UK, Wafer Fab or Magnachip-Wise Road Capital acquisitions.

Chinese manufacturers are also investing in technology knowledge. If we look five years back, Chinese products were believed to be lower performance than EU, Japan, or US manufacturers for high-end components like super junction MOSFETs. However, this is changing. Some Chinese companies can actually achieve similar performances to key MOSFET players.

All in all, Chinese manufacturers are racing to capture a big portion of the MOSFET market. This Yole Développement report contains a deep analysis of the Chinese supply chain and product benchmarking.
