STMicroelectronics is a Swiss-domiciled multinational electronics and semiconductor manufacturer headquartered in Geneva, Switzerland. It is commonly called ST, and it is Europe’s largest semiconductor chip maker based on revenue. While STMicroelectronics corporate headquarters and the headquarters for EMEA region are based in Geneva, the holding company, STMicroelectronics N.V. is incorporated in the Netherlands. The company originates from France and Italy.

The company’s US headquarters is in Coppell, Texas. Headquarters for the Asia-Pacific region is in Singapore whilst Japan and Korea operations are headquartered in Tokyo. The company headquarters for the Greater China region is in Shanghai.

STMicroelectronics Portfolio

ST was formed in 1987 by the merger of two government-owned semiconductor companies: SGS Microelettronica (Società Generale Semiconduttori) of Italy and Thomson Semiconducteurs, the semiconductor arm of France’s Thomson.

SGS Microelettronica originated in 1972 from a previous merger of two companies – ATES (Aquila Tubi e Semiconduttori), a vacuum tube and semiconductor maker headquartered in the Abruzzese city of l’Aquila, which in 1961 changed its name to Azienda Tecnica ed Elettronica del Sud and relocated its manufacturing plant to the outskirts of the Sicilian city of Catania, and Società Generale Semiconduttori, which was founded in 1957 by Adriano Olivetti.

Thomson Semiconducteurs was created in 1982 by the French government’s widespread nationalisation of industries. It included the semiconductor activities of the French electronics company Thomson. In 1985 it bought Mostek, a US company founded in 1969 as a spin-off of Texas Instruments, from United Technologies; Silec, founded in 1977; Eurotechnique founded in 1979 in Rousset, Bouches-du-Rhône as a joint-venture between Saint-Gobain of France and US-based National Semiconductor; EFCIS, founded in 1977; and SESCOSEM, founded in 1969.

At the time of the merger the company was named SGS-THOMSON but took its current name in May 1998 following Thomson’s sale of its shares. After its creation ST was ranked 14th among the top 20 semiconductor suppliers with sales of around US$850 million.

The company has participated in the consolidation of the semiconductor industry since its formation, with acquisitions including

  • 4 Field-Programmable Microcontroller Peripheral from Wafer Scale Integration PSD311
  • 1989, British company Inmos known for its transputer microprocessors from parent Thorn EMI
  • In 1994, Canada-based Nortel’s semiconductor activities
  • 2000, WaferScale Integration Inc. (WSI, Fremont, California), a vendor of EPROM and flash memory-based programmable system-chips
  • In 2002, Alcatel’s Microelectronics division, which along with the incorporation of smaller ventures such as UK company, Synad Ltd, helped the company expand into the Wireless-LAN market
  • In 2007, US-based Genesis Microchip. Genesis Microchip is known for their strength in video processing technology (Faroudja) and has design centres located in Santa Clara, Toronto, Taipei City, Taiwan R.O.C. and Bangalore

On December 8, 1994, the company completed its initial public offering on the Paris and New York stock exchanges. Owner Thomson SA sold its stake in the company in 1998 when the company also listed on the Borsa Italiana in Milan.

In 2002, Motorola and TSMC joined ST and Philips in a new technology partnership. The Crolles2 Alliance was created with a new 12″ wafer manufacturing facility located in Crolles (France).

By 2005, ST was ranked fifth, behind Intel, Samsung, Texas Instruments and Toshiba, but ahead of Infineon, Renesas, NEC, NXP, and Freescale. The company was the largest European semiconductors supplier, ahead of Infineon and NXP.

Early in 2007, NXP (formerly Philips Semiconductors) and Freescale (formerly Motorola Semiconductors) decided to stop their participation in Crolles2 Alliance. Under the terms of the agreement the Alliance came to an end on December 31, 2007.

On May 22, 2007, ST and Intel created a joint venture in the memory application called Numonyx. This new company merged ST and Intel Flash Memory activities. Semiconductor market consolidation continued with ST and NXP announcing on April 10, 2008, the creation of a new joint venture of their mobile activities, with ST owning 80% of the new company and NXP 20%. This joint venture began on August 20, 2008.

On February 10, 2009, ST Ericsson, a joint venture bringing together ST-NXP Wireless and Ericsson Mobile Platforms, was established.

In 2011, ST announced the creation of a joint lab with Sant’Anna School of Advanced Studies. The lab will focus on research and innovation in bio-robotics, smart systems and microelectronics. Past collaborations with Sant’Anna School of Advanced Studies included DustBot, a platform that integrated self-navigating “service robots” for waste collection.

ST Ericsson was a multinational manufacturer of wireless products and semiconductors, supplying to mobile device manufacturers. ST-Ericsson was a 50/50 joint venture of Ericsson and STMicroelectronics established on February 3, 2009, and dissolved on August 2, 2013. Headquartered in Geneva, Switzerland, it was a fabless company, outsourcing semiconductor manufacturing to foundry companies.

Unlike fabless semiconductor companies, STMicroelectronics owns and operates its own semiconductor wafer fabs. The company owned five 8 inch (200 mm) wafer fabs and one 12 inch (300 mm) wafer fab in 2006. Most of the production is scaled at 0.18 µm, 0.13 µm, 90 nm and 65 nm (measurements of transistor gate length). STMicroelectronics also owns back-end plants, where silicon dies are assembled and bonded into plastic or ceramic packages.

Rohm Semiconductor is a Japanese electronic parts manufacturer based in Kyoto, Japan. It was incorporated as Toyo Electronics Industry Corporation by Kenichiro Sato on September 17, 1958.

The company was initially known as R.ohm, which was derived from R for resistors, the original product, plus ohm, the unit of measure for resistance. The “R” now also stands for “Reliability”. “Quality First” is ROHM’s corporate policy.

The name of the company was officially changed to Rohm in 1979 and then changed again to Rohm Semiconductor in January 2009.

When Rohm was established, resistors were its main product. Later, the company began manufacturing semiconductors. ICs and discrete semiconductors now account for about 80% of Rohm’s revenue.

Through 2012, Rohm was among the top 20 semiconductor sales leaders.

ROHM was established in Kyoto in 1958 as initially a manufacturer of small electronic components. In 1967 production was expanded to include transistors and diodes, and in 1969 ICs and other semiconductor products were added to the lineup. Two years later (in 1971), going against conventional Japanese business culture, the company entered the US market by establishing a sales office and IC design center in Silicon Valley.

Through the hard work and passionate dedication of its young work force, business flourished, causing the industry to take notice. ROHM’s expansion overseas soon became a template for other companies and eventually was accepted as common business practice.


Toshiba Corporation is a Japanese multinational conglomerate headquartered in Minato, Tokyo. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives, printers, batteries, lighting, logistics, as well as IT solutions such as quantum cryptography. It was one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment.

As a semiconductor company and the inventor of flash memory, Toshiba had been one of the top 10 in the chip industry until its flash memory unit was spun off as Toshiba Memory, later Kioxia, in the late 2010s.

Toshiba was founded in 1939 as Tokyo Shibaura Denki K.K. (Tokyo Shibaura Electric Co., Ltd) through the merger of Shibaura Seisaku-sho (founded in 1875) and Tokyo Denki (founded in 1890). The company name was officially changed to Toshiba Corporation in 1978.

Having been a technology company with a long history and sprawling businesses, Toshiba has been a household name in Japan and looked upon as a symbol of the country’s technological prowess.

Tanaka Seisakusho (Tanaka Engineering Works) was the first company established by Tanaka Hisashige, one of the most original and productive inventor-engineers during the Tokugawa/Edo period. Established in July 1875, it was the first Japanese company to manufacture telegraph equipment. It also manufactured switches, and miscellaneous electrical and communications equipment.

The company was inherited by Tanaka’s adopted son, and later became half of the present Toshiba company. Several people who worked at Tanaka Seisakusho or who received Tanaka’s guidance at a Kubusho (Ministry of Industries) factory later became pioneers themselves.

These included Miyoshi Shōichi who helped Fujioka make the first power generator in Japan and to establish a company, Hakunetsusha to make bulbs; Oki Kibatarō, the founder of the present Oki Denki (Oki Electric Industry); and Ishiguro Keizaburō, a co-founder of the present Anritsu.

Toshiba IEGT Power Semiconductor

After the demise of the founder in 1881 Tanaka Seisakusho became partly owned by General Electric and expanded into the production of torpedoes and mines at the request of the Imperial Japanese Navy, to become on the largest manufacturing companies of the time.

However, as the Navy started to use competitive bids and then build its own works, the demand decreased substantially and the company started to lose money. The main creditor to the company, Mitsui Bank, took over the insolvent company in 1893 and renamed it Shibaura Seisakusho (Shibaura Engineering Works).

In 1910, it formed a tie-up with General Electric in the US, which, in exchange for technology acquired about a quarter of the shares of Shibaura. With this investment, GE now had a stake in both Tokyo Denki and Shibaura Seisakusho – two companies that had a complementary line of products in the light as well as heavy electrical equipment.

Both companies were merged in 1939 to create Tokyo Shibaura Denki (Tokyo Shibaura Electric Company, now Toshiba). The relation with GE continued until the beginning of the war and, after the war, resumed in 1953 with GE’s 24 percent shareholding. This percentage has, however, decreased substantially since then.

Hakunetsusha was a company established by Shōichi Miyoshi and Fujioka Ichisuke, two of Japan’s industrial pioneers during the Tokugawa/Edo period. It specialized in the manufacture of light bulbs. The company was established in 1890 and started out by selling bulbs using bamboo filaments.

Toshiba Power Devices Product Guide

In 1905 the company was renamed Tokyo Denki (Tokyo Electric) and entered into a financial and technological collaboration with General Electric of the US. General Electric acquired 51 percent share of ownership, sent a vice president, and provided the technology for bulb-making. Production equipment was bought from GE and Tokyo Denki soon started selling its products with GE’s trademark.

In 1939, Tokyo Denki and Shibaura Seisakusho were merged to form Tokyo Shibaura Denki (Tokyo Shibaura Electric Company, now Toshiba).

The group expanded rapidly, driven by a combination of organic growth and by acquisitions, buying heavy engineering, and primary industry firms in the 1940s and 1950s. In 1950, Tokyo Shibaura Denki was renamed Toshiba.

In October 2020, Toshiba made a decision to pull out of the system LSI business citing mounted losses while reportedly mulling on the sale of its semiconductor fabs as well.

Of course, worldwide there are many more manufacturers of power semiconductors working in various segments of power electronics market. However, the listed above companies hold the bigger part of power semiconductors market, and are considered to be the major manufacturers of power semiconductors.
