ABSTRACT:
A body of p-type indium phosphide, which was heretofore difficult to contact in a reliable low resistance manner, is ohmically contacted by an alloy contact of bismuth with preferably 2% zinc. The alloy contact is effected by placing a small pellet of the Bi-Zn alloy on the surface of the p-type InP body and then alloying at a preferred temperature of 360.degree. C for 20 seconds.
