description PROBLEM TO BE SOLVED: To provide a method of producing a silicon carbide semiconductor device in which there is no occurence of roughness over the entire surface of a silicon carbide wafer.SOLUTION: A method of producing a silicon carbide semiconductor device comprises a step of performing ion injection of an impurity 30i into a silicon carbide wafer 10, a step of forming a diamond layer 40 on the silicon carbide wafer 10 into which ion injection of the impurity 30i is performed and a step of performing a heat treatment to the silicon carbide wafer 10 on which the diamond layer 40 is formed so as to form an impurity region 30 in which the impurity 30i is activated in the silicon carbide wafer 10.
