New Raytheon Factory Fabricates Silicon Carbide Electronics

Raytheon has set up a new silicon carbide plant in Scotland. The
silicon carbide foundry opened in January 2013 in Glenrothes, about
20 miles (30 kilometers) north of Edinburgh in Scotland’s “Silicon
Glen” high-tech region. The company’s technicians are using
high-voltage beams of ions, to build circuits from synthetic wafers
of silicon carbide. The resulting electronic circuits can withstand
blazing temperatures.

Raytheon workers in Glenrothes also make more conventional
electronic circuits from silicon. But silicon carbide is a much
harder material that is often used as a substitute for diamonds in
jewelry or cutting tools. In the foundry’s clean room, Raytheon
technicians will shoot streams of charged ions at 4-inch
(100-millimeter) wafers of silicon carbide, implanting them in the
material and permanently altering their conductivity
