Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:forming a conductive thin film by sputtering on a semiconductor substrate having a selectively exposed surface, said conductive thin film comprising a main component having magnetic properties and consisting of a metal or an alloy and a sub-component comprising at least one metal capable of reducing a natural oxide film on said semiconductor substrate,heating said semiconductor substrate to react said substrate with said conductive thin film, thereby forming a first compound layer comprising a semiconductor constituting said substrate and the metal constituting said main component of said conductive thin film,removing an unreacted portion of said conductive thin film from said first compound layer on said selectively exposed surface of said semiconductor substrate, andheating said semiconductor substrate to react said substrate with said first compound layer, thereby forming a second compound layer comprising said semiconductor constituting said substrate at a higher ratio than said first compound layer.
