Founded in 1992, Transys now owns and operates a full capability 5000 square foot power semiconductor waferfab along with vacuum soldering assembly capability. They are capable of producing 4,000, 4, 5, and 8-inch power semiconductor wafers per week.


The key product technologies include IGBT’s, customised MOSFET’s, Power Transistors and Transient Voltage Suppressors (TVS).

They have a full range of processing capability. Diffusion for both Planar and Mesa products, both advanced and Ion implantation and more rugged Gas and Film dopants are used.

Photolithography, plasma and chemical etch, plus sputtering, evaporated metal systems and dicing, all take place on-site in the UK.
