Abstract

Ohmic contacts to p-type IIB/VIB semiconductor are obtained by a process which includes the step of depositing a viscous liquid containing a Group IB metal salt on a surface of a semiconductor, substantially free of oxide groups, heating to form a dried layer, removing the dried layer, washing the surface to remove residual by-products and drying the surface.
