Abstract:
A semiconductor device includes an n-type silicon carbide epitaxial layer on a front surface of an n + -type silicon carbide substrate. A first p + -type base region is provided in the n-type silicon carbide epitaxial layer and a breakdown voltage structure region is provided in an outer periphery of an active region through which a main current flows. A distance between the first p + -type base region and a front surface of the n + -type silicon carbide substrate is smaller than a distance between the breakdown voltage structure region and the front surface of the n + -type silicon carbide substrate.

Claim (Index 3):
The semiconductor device according to  claim 2 , wherein an impurity concentration of the breakdown voltage structure region is at least 1.0\u00d710 17 /cm 3 , and\n the breakdown voltage structure region extends until at least 5.0 \u03bcm farther than an outermost periphery of the first base region in the plan view.
