Disclosed is a method for manufacturing a Schottky barrier diode. An insulating film is formed on a silicon substrate of one conductivity type. The insulating film has a hole therein partially exposing the surface of the silicon substrate. Then, a polycrystalline silicon layer is formed to cover that portion of the insulating film which surrounds the contact hole, the inner wall of the contact hole, and the exposed surface portion of the silicon substrate. Thereafter, a metal layer is deposited to cover at least the polycrystalline silicon layer. The polycrystalline silicon is then alloyed with the metal to form a metal silicide layer.
