Welcome to CST

In 2010 CST completed the transfer and requalification of its unique process library from its previous base in Glasgow to its new home in Hamilton.

CST intends to utilise the new facility to expand on its wide variety of solutions for III-V devices from 4XXnm to 3.9um in the Communications, Defence, Consumer and Industrial markets.

CST is a 'pure play' semiconductor foundry and custom service provider specialising in the design, development and manufacture of discrete and integrated III-V opto-electronic devices, based in the UK.
