Abstract
A method is disclosed for fabricating ohmic contacts on semiconducting diamond. A carbide forming metal is deposited over a surface of the semiconducting diamond. In some applications, one or more layers of an intermediate metal are deposited over the carbide forming metal. A corrosion resistant metal is then deposited over the intermediate metal, if present, or the carbide forming metal. The semiconducting diamond and metals are heated in an inert environment at a temperature anywhere from 350 to 1200 degrees Celsius.
