A method of forming an ohmic contact between an amorphous silicon hydride semiconductor and a substrate which includes coating a film of palladium on the substrate and overcoating the palladium with a thin film of amorphous silicon hydride forming a thin palladium silicide layer. The amorphous silicon hydride is dehydrogenated by annealing forming a highly defective amorphous silicon layer and a thicker palladium silicide layer through which carriers can readily tunnel. The amorphous silicon hydride semiconductor is then coated over the amorphous silicon layer to the desired thickness.
