III-V optoelectronic foundry Compound Semiconductor Technologies Global Ltd (CST Global) of Scotland, UK (a subsidiary of Sweden’s Sivers IMA Holdings AB) has commissioned its second metal-organic chemical vapor deposition (MOCVD) reactor.
The reactor is the result of a novel, academic/industrial collaboration. It is owned by the University of Glasgow but sited, managed and operated at CST Global’s production site in Blantyre, Glasgow. This unique approach allows CST Global to undertake joint research projects under the guidance of Richard Hogg, Professor of Photonics at the University of Glasgow, without downtime on commercial MOCVD production. CST Global also gains additional MOCVD capacity as part of the collaboration.
“This exciting new MOCVD capability will enable development projects in bespoke III-V structures within an industrial setting,” says Hogg. “We can now realise a range of advanced electronic and photonic devices,” he adds.
“We can harness the benefits of siting the reactor in a professional manufacturing environment with access to excellent facilitation, safety systems, quality and exploitation routes. We can now service academic groups and industrial partners around the world developing and delivering the high-quality devices they need for advanced semiconductor research, in the timescales they require,” he continues.
“Two projects are already in development. The reactor has a unique, high-temperature operation which facilitates indium phosphide (InP) laser production using overgrowth on silicon wafers. Since silicon wafers are a fraction of the price of III-V compound semiconductor wafers, a potential drop in laser cost is worth investigating,” Hogg says. “We are also adding the capacity for iron (Fe) doping for heat dissipation to allow increased power and brightness in both DFB (distributed feedback) and BH (buried heterostructure) lasers.”
All development projects are funded by the Engineering and Physical Sciences Research Council (EPSRC) and UK Government agency Innovate UK, between the University of Glasgow and CST Global.
