Original Abstract Submitted
A semiconductor device includes: an N drift layer of a first conductivity type formed in the semiconductor substrate; a P base layer formed on the N drift layer; and an N buffer layer of the first conductivity type formed under the N drift layer and higher in peak impurity concentration than the N drift layer. The N buffer layer includes: a first buffer layer in which a trap level derived from lattice defect is not detected by a photoluminescence method; and a second buffer layer provided between the first buffer layer and the N drift layer and in which two types of trap levels derived from lattice defect are detected by the photoluminescence method.
