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 7):
The semiconductor device according to  claim 1 , further comprising\n a second buffer layer formed in a side of the one main surface of the first buffer layer.
