Abstract

It is aimed to reduce a current concentration at the edge of the contact electrode. Provided is a semiconductor device including a semiconductor layer, a first trench electrode formed in the semiconductor layer on a front surface side thereof, and a second trench electrode formed in the semiconductor layer on the front surface side thereof so as to oppose the first trench electrode. Here, the first trench electrode is formed in a mesh-like pattern. The semiconductor layer may further include a first-conductivity-type region and a second-conductivity-type region having a different conductivity type than the first-conductivity-type region. The first trench electrode may be electrically connected to the first-conductivity-type region, and the second trench electrode may be electrically connected to the second-conductivity-type region.
