Who We Are

STMicroelectronics was created in 1987 by the merger of two long-established semiconductor companies, SGS Microelettronica of Italy and Thomson Semiconducteurs of France, and has been publicly traded since 1994; its shares trade on the New York Stock Exchange (NYSE: STM), on Euronext Paris, and on Borsa Italiana. 

The group has approximately 43,600 employees, 11 main manufacturing sites, advanced research and development centers in 10 countries, and sales offices all around the world.

Corporate Headquarters, as well as the headquarters for Europe, the Middle East and Africa, (EMEA) are in Geneva. The Company’s Americas Headquarters are in Coppell (Texas); those for Greater China and South Asia are based in Shanghai; and Japanese and Korean operations are headquartered in Tokyo.

Research & Development

Since its creation, ST has maintained an unwavering commitment to R&D. Almost one fifth of its employees work in R&D and product design and in 2014 the Company spent about 21% of its revenue in R&D. Among the industry’s most innovative companies, ST owns almost 15,000 patents and pending applications corresponding to over 9,000 patent families, including more than 500 original new patent applications filed in 2014. The Company draws on a rich pool of chip fabrication technologies, including advanced FD-SOI (Fully Depleted Silicon-on-Insulator) CMOS (Complementary Metal Oxide Semiconductor), mixed-signal, analog and power processes.  From its inception, ST has established a strong culture of partnership and through the years has created a worldwide network of strategic alliances with key customers, suppliers, competitors, and leading universities and research institutes around the world.


To provide its customers with an independent, secure and cost-effective manufacturing machine, ST operates a worldwide network of front-end (wafer fabrication) and back-end (assembly and test and packaging) plants. ST’s principal wafer fabs are located in Agrate Brianza and Catania (Italy), Crolles, Rousset and Tours (France), and in Singapore. The wafer fabs are complemented by world-class assembly-and-test facilities located in China, Malaysia, Malta, Morocco, the Philippines and Singapore.


STMicroelectronics was one of the first global industrial companies to recognize the importance of environmental responsibility and, over the past 15 years, the Company’s sites have received more than 100 awards for excellence in all areas of Sustainability, from quality and product responsibility to corporate governance, social issues, employee health and safety, and environmental protection. Our approach to sustainability is set out in ST’s Principles for Sustainable Excellence, while our performance is reported in detail in our annual Sustainability Reports.
