Abstract

Generally, a complicated process is required in manufacturing a semiconductor device containing a Schottky barrier diode and a polycrystalline silicon layer which prevents excessive reaction of the aluminum electrode and silicon material involved. Because of the inability of the aluminum electrode to provide a good Schottky barrier by its contact with the polycrystalline silicon layer, it is required to directly contact the electrode with a monocrystalline silicon semiconductor layer or substrate. According to the present invention, this process is simplified by monocrystallizing the polycrystalline silicon layer at least in the region in which a Schottky barrier diode is to be formed by annealing the silicon layer in said region by laser beam irradiation and applying an aluminum electrode thereto.
