MBE Epiwafers


Mi-Net Technology Ltd is the UK sales agent for Picogiga International SAS of France.


The compound semiconductor industry emerged in the early 1980s to help meet the increasingly stringent manufacturing demands associated with high-frequency electronics and optoelectronics products. Founded in 1985, Picogiga SA was an early leader in this market, specializing in gallium arsenide (GaAs) material. Thanks to its mastery of molecular beam epitaxy technology (MBE), the company became a world-leading supplier of epitaxial compound semiconductor wafers for microwaves and RF applications.

In April 2003, Soitec, the world leader in silicon-on-insulator (SOI) material and other engineered substrates acquired the assets of Picogiga SA, including most of the key personnel, creating a new, wholly owned Soitec Group subsidiary-Picogiga International SAS-concentrated on the development and manufacturing of compound semiconductor products.

In January 2004, Soitec-Picogiga became the first commercial company to launch industrial production of GaN epitaxial structures on Silicon substrate required to manufacture high-electron-mobility transistors (HEMTs) used in wireless-infrastructure and other high power RF applications.

Knowledge & Expertise

A valued partner in the field of substrate engineering for III-V material applications, Picogiga is now quite unique in the compound semiconductor industry due to its ability to grow epi wafers and develop multilayer substrates tailored for specific applications. Leveraging its proven experience growing epitaxial layers on GaAs and other compound semiconductor substrates using MBE technology, Picogiga International is now targeting new markets requiring specific composite materials. These include indium phosphide (InP), gallium nitride (GaN)and silicon carbide (SiC), as well as GaAs, all of which are being pursued for high-frequency, high-power applications (e.g., mobile telecommunications, local networks and radar detection) and optoelectronic devices (e.g., detection systems, Fiber optics networks, LEDs and lasers).
