Abstract:
In a process for manufacturing a semiconductor device, the improvement of forming a doped crystalline semiconductor on a substrate by a method of comprising:(a) depositing a semiconductor onto the substrate to form a semiconductor layer having an amorphous region; (b) depositing a layer of doping metal onto the amorphous region of the semiconductor layer to form a structure comprising the substrate, semiconductor layer and doping 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 doped with the doping metal, wherein the doping metal promotes the conversion of the at least a portion of the amorphous region into the crystalline semiconductor.
