PEATER - Facilities

Science City Cleanroom

The Science City cleanroom facility is a semiconductor fabrication laboratory in the School of Engineering dedicated to the manufacture of semiconductor devices. It is a state-of-the-art facility, operated as part of the Science City partnership with the University of Birmingham, for silicon carbide processing. The facility is a 150 m2 ISO class 6 cleanroom, with the air filtered to 1000 times normal quality. This allows for the manufacture and testing of experimental electronic devices, as the facility is equipped with lithography, etching, deposition, oxidation, annealing and testing capabilities.

Operational from early 2010, the specialised laboratory includes a semiconductor Class 1000 cleanroom, humidity controlled, with a yellow room for photolithography capable of 0.75 micron lithography and a suite of processing equipment.

The laboratory provides for research into the materials physics and device fabrication technology of silicon carbide. It also functions as an incubator unit for development of new device concepts and prototype devices for the power electronics systems community, both academic and industrial.
