Sustainable by design
How Soitec drives innovation in the electronics value chain
Soitec partners with leading silicon manufacturers to source raw wafers, meticulously crafted through smelting, casting, and cutting. Using the revolutionary Smart Cut&trade process, developed in the heart of Grenoble’s innovation hub, Soitec leverages nanotechnology at an atomic scale to create silicon-on-insulator (SOI) wafers.
This cutting-edge technology introduces an insulating layer between two silicon oxide layers, enhancing energy efficiency and boosting performance. By simplifying device architecture, SOI wafers also lower manufacturing costs, driving both innovation and sustainability in electronic components.
With its Smart Cut™ process, Soitec enables integrated circuit manufacturers to develop next-generation microelectronics that power a smarter, more energy-efficient future.
A unique business model to set an industry standard
Soitec has the largest industrial manufacturing site for SOI wafers (200 mm to 300 mm) in the world. It includes 4,500 m² of cleanrooms spread out between its three factories in France. In 2015, Soitec partnered with the Chinese company Simgui to manufacture 200-mm SOI wafers for the Chinese market and operate as a manufacturing partner (foundry model) for Soitec customers outside of China. Soitec also has a FD-SOI pilot line in Singapore.
The company introduced the Smart Cut™ technology on the market on an industrial scale, which today is used to make nearly all SOI wafers sold in the world. Soitec has licensed SOI technology to several leading wafer manufacturers including the Japanese company Shin-Etsu Handotai (SEH) in 1997 which continues to this date as well as to Simgui for manufacturing and selling certain 150 mm and 200 mm SOI products to Soitec exclusively.
