Abstract:
An object of the present invention is to provide a semiconductor device capable of preventing an occurrence of oscillation of voltage and current and a method of manufacturing the same. A semiconductor device according to the present invention includes an n type silicon substrate and a first n type buffer layer formed in a back surface of the n type silicon substrate and having a plurality of peaks of concentration of protons whose depths from the back surface are different from each other. In the first n type buffer layer, a concentration gradient of the protons from the peak located in a position closer to the back surface toward the surface of the n type silicon substrate is smaller than a concentration gradient of the protons from the peak located in a position farther away from the back surface toward the surface.

Claim (Index 13):
The semiconductor device according to  claim 10 , wherein\n in the first buffer layer, each of the plurality of peaks of the concentration of the protons becomes smaller from the one main surface toward the another main surface of the semiconductor substrate.
