Patent ID: 8039204

Claim:
A manufacturing method of a silicon carbide semiconductor apparatus, the method comprising: forming a first resist pattern on a surface of a silicon carbide layer formed on a silicon carbide substrate; implanting a first conduction type impurity ion in the silicon carbide layer on which the first resist pattern is formed; forming a second resist pattern by decreasing a width of the first resist pattern with etching and forming a deposition layer on the surface of the silicon carbide layer which is not covered with the second resist pattern, the deposition layer being a reaction product in which plasmas of etching gases including deposition effect gas react mutually, or a reaction product between a plasma of the etching gas including the deposition effect gas and the first resist pattern constructed of an organic material; and implanting a second conduction type impurity ion in the silicon carbide layer on which the second resist pattern is formed, through the deposition layer.
