Abstract:
1. A semiconductor device production method for producing a semiconductor device by forming an impurity region in a front surface of a silicon carbide semiconductor substrate, the method comprising the steps of: holding the silicon carbide seiconductor substrate by a susceptor of carbon with a rear surface of the substrate in contact with the susceptor; bringing a heating member of carbon into contact with the front surface of the silicon carbide semiconductor substrate selectively ion-implanted with an impurity element; and heat-treating the silicon carbide semiconductor substrate with the heating member in contact with the front surface of the silicon carbide semiconductor substrate, wherein the heating member contacting step is the step of bringing the heating member into contact with the front surface of the silicon carbide semiconductor substrate held by the susceptor, the heat treating step is the step of causing the susceptor and the heating member to generate heat through high frequency induction heating for heat treatment and the susceptor has a surface coated by high purity carbon CVD.
