Abstract: A method for manufacturing a semiconductor device includes the steps of forming a metal film (Ni film) over the bottom surface of a contact hole that exposes a portion including SiC at the bottom surface, and performing a heat treatment to form a silicide film at the bottom surface of the contact hole by a silicidation reaction of the metal film MT and the portion including SiC. Also, the heat treatment step is a step of irradiating a laser beam on the surface of a SiC substrate. As the heat treatment, annealing is performed using the laser beam that goes through SiC and is absorbed by metal (Ni and the like).
