Soitec is a France-based international industrial company specialized in generating and manufacturing high performance semiconductor materials. The company operates on three main markets: electronics, solar energy and lighting. Soitec is listed on the Paris stock exchange (Euronext Compartment B).


Soitec was founded in 1992 near Grenoble in France by two researchers from CEA-Leti, an institute for micro- and nanotechnologies research created by the French Commission for Atomic Energy and Alternative Energies (CEA). The pair developed Smart Cut™ technology to industrialize Silicon-On-Insulator (SOI) wafers, and built their first production unit in Bernin, in the Isère department of France. By applying this technology to materials other than silicon and developing further processes, Soitec has built up expertise in the field of semiconductor materials. Soitec’s offering initially targeted the electronics market. Then, at the end of the 2000s, Soitec launched into the solar energy and lighting markets, exploiting new openings for its materials and technologies. The company currently has production units in France and the United States, and is present (though R&D centers, sales offices, etc.) in Europe (Germany and Italy), the United States (Arizona, California and Massachusetts), Asia (China, Korea, Japan, Singapore and Taiwan) and South Africa.

Soitec operates on three markets: electronics, solar energy and lighting.


Historically, Soitec has marketed Silicon On Insulator (SOI) as a high performance material for manufacturing electronic chips for computers, game consoles and servers, as well as the automotive industry. With the explosion of mobile products (tablets, smartphones, etc.) on the consumer electronics market, Soitec has also developed new materials for radio-frequency components, multimedia processors, etc.

Solar energy[edit]

Soitec manufacturers and supplies Concentrator Photovoltaic (CPV) systems. Its main market is large-scale solar power plants located in regions with strong direct sunlight. Soitec has installed CPV power plants or demonstration systems in 28 countries, representing a total installed capacity of 75 MWp.[1] Its main installations are located in South Africa and the United States. In France, as part of the second call for tender for large-scale solar power plants launched by the French Energy Regulation Commission (CRE), Soitec and Alstom signed a cooperation agreement[2] in July 2013 to combine their expertise in concentrator photovoltaic technology on the one hand, and delivering turnkey power plants and providing integrated solutions and equipment and power generation on the other. In April 2014, Soitec announces that its CPV modules are included in 13 projects selected by the French Energy Regulation Commission in its second call for tenders.


Soitec operates upstream and downstream of the LED value chain. Upstream, the company uses its expertise in semiconductor materials to develop substrates made from gallium nitride (GaN), the base material used in LEDs. Its technologies have been licensed through several agreements, notably with Sumitomo and GT Advanced Technologies. Downstream, Soitec is developing a range of industrial partnerships to commercialize new professional lighting solutions (urban, office and transport infrastructure lighting). The company was awarded one lot in a call for tender launched in 2012 by France’s RATP to replace the lighting in the Paris Metro underground and RER urban train network.


Soitec is developing numerous technologies for its different sectors of activity.

Smart Cut™[edit]

Developed by CEA-Leti in collaboration with Soitec,[3] this technology has been patented by researcher Michel Bruel.[4] It makes possible the transfer of a thin layer of monocristalline material from a donor substrate to another by combining ion implantation and bonding by molecular adhesion. Soitec uses Smart Cut™ technology to mass-produce SOI wafers. Compared with classic bulk silicon, SOI enables a significant reduction in energy leakage in the substrate, and improves the performance of the circuit in which it is used.

Smart Stacking™[edit]

This technology involves the transfer of partially or fully processed wafers onto other wafers. It can be adapted to wafer diameters of 150 mm to 300 mm and is compatible with a wide variety of substrates, such as silicon, glass and sapphire. Smart Stacking™ technology is used for back-side illuminated image sensors, where it improves sensitivity and enables a smaller pixel size, as well as in smartphone radio-frequency circuits. It also opens new doors to 3D integration.


Soitec has epitaxy expertise in III-IV materials across the following fields: molecular beam epitaxy, metal organic vapor phase epitaxy deposition and hydride vapor phase epitaxy. The company manufactures wafers of gallium arsenide (GaAs) and gallium nitride (GaN) for developing and manufacturing compound semiconductor systems. These materials are used in Wi-Fi and high-frequency electronic devices (mobile telecommunications, infrastructure networks, satellite communications, fiber optic networks and radar detection), as well as in energy management and optoelectronic systems, such as LEDs.

Concentrating Photovoltaic (CPV) technology[edit]

Concentrating photovoltaic (CPV) technology was developed by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Germany. It is based on the use of modules comprising two glass plates held together by a metallic frame. The light arriving on the top plate is concentrated by a factor of 500, thanks to optic lenses made from silicon on glass (known as Fresnel lenses). After concentration, it is converted into electricity by multi-junction solar cells mounted on the bottom plate. Soitec modules achieve 31.8 percent efficiency. The company is carrying out R&D work to develop its own cells. Together with Fraunhofer ISE, CEA-Leti and the Helmholtz Center Berlin, Soitec recently announced a world record in the laboratory, with cells achieving 44.7[5] percent efficiency. Soitec has also used its CPV technology to develop Plug&Sun™ mini-trackers, capable of producing solar electricity autonomously in areas that are isolated or poorly connected to electricity grids.

In 2011, Soitec unveiled the Sunidarity initiative. A call for tender was launched among NGOS, foundations and associations to identify local humanitarian development projects involving the use of solar electricity. The awarded projects were provided with Plug&Sun™ equipment. Four projects were selected in 2012 for electrification work in Haiti, Lebanon, Madagascar and Palestine.

Ethical code[edit]

Since 2012, Soitec has adopted a code of conduct, which applies to all its employees in all the countries in which the group operates. This code also governs Soitec’s relations with shareholders, clients and suppliers, as well as with public bodies, administrations, etc.

High Tech U[edit]

In 2007, Soitec introduced the High Tech U[11] project, an initiative of the SEMI (Semiconductor Equipment and Materials International) Foundation, an international association of semiconductor manufacturers that develops campaigns to raise young people’s awareness of careers in the sciences. Ten discovery and observation days were designed in partnership with Grenoble Institute of Technology (Grenoble INP) and ST Microelectronics.
