Abstract:
In a process for manufacturing a semiconductor device, the improvement of forming a crystalline semiconductor on a substrate by a method comprising:(a) depositing a semiconductor onto the substrate to form a semiconductor layer having an amorphous region; (b) depositing a layer of metal onto the amorphous region of the semiconductor layer to form a structure comprising the substrate, semiconductor layer and metal layer; and (c) annealing the structure at a temperature in the range of about 170Â° C. to about 600Â° C. to convert at least a portion of the amorphous region into a crystalline semiconductor, wherein the metal of a first portion of the metal layer promotes the conversion of the at least a portion of the amorphous region into the crystalline semiconductor and the metal of a second portion of the metal layer provides an electrical contact to the crystalline semiconductor.
