Abstract
A method of forming an electrical contact to a shallow junction silicon semiconductor device such as a solar cell comprises evaporating a sufficient amount of a metal which upon heating will form a silicide with the silicon to a predetermined depth and thereafter oxidizing the surface of the silicon so as to form a shallower junction in the unoxidized portions of said silicon. The portion of the silicon device which has formed the silicide does not oxidize and forms an electrical contact to the silicon. In addition, the metal silicide can have additional metal plated thereto to lower the sheet resistivity and resistance of the electrical contact.
