Abstract:
On a front surface of a semiconductor base, a first n − -type drift region and a second n-type drift region are provided. A gate trench is provided that penetrates an n + -type source region and p-type base region, and reaches the second n-type drift region. Between adjacent gate trenches, a contact trench is provided that penetrates the n + -type source region and the p-type base region, and reaches a p-type semiconductor region, through the second n-type drift region. A source electrode embedded in the contact trench is in contact with the p-type semiconductor region at a bottom and corners of the contact trench, and forms a Schottky junction with the second n-type drift region at side walls of the contact trench. A depth of the contact trench is a depth by which a mathematical area of a part thereof forming the Schottky junction is a predetermined mathematical area or greater.

Claim (Index 8):
The semiconductor device according to  claim 1 , wherein the second trench has a depth ranging from 1.8 \u03bcm to 3.0 \u03bcm.
