Abstract:
A method for manufacturing a semiconductor device having a edge termination region comprises a stacking process, an ion implantation process, and a heat treatment process. In the stacking process, a p-type semiconductor layer containing a p-type impurity is stacked on an n-type semiconductor layer containing an n-type impurity. In the ion implantation process, at least one of the n-type impurity and the p-type impurity is ion-implanted into the p-type semiconductor layer located in the edge termination region. The ion implantation process and the heat treatment process are performed such that the p-type impurity of the p-type semiconductor layer is diffused into the n-type semiconductor layer to form a p-type impurity containing region in at least part of the n-type semiconductor layer and below a region of the p-type semiconductor layer into which the ion implantation has been performed.

Claim (Index 2):
The method for manufacturing the semiconductor device in accordance with  claim 1 , further comprising:\n a trench forming process that forms a trench that is recessed to pass through the p-type semiconductor layer and reach the n-type semiconductor layer, wherein in a stacking direction of the n-type semiconductor layer and the p-type semiconductor layer, a bottom face of the p-type impurity containing region is located to be coplanar with a bottom face of the trench or below the bottom face of the trench.
