Abstract:
A method of manufacturing a semiconductor device includes forming a base layer in an upper part of a substrate and a trench in the substrate. A gate insulating film is on an inner bottom surface and an inner side surface of the trench and a gate electrode is embedded into the trench. The gate electrode is etched so that an upper surface of the gate electrode is at a first height from the bottom of the trench. A source region is in contact with an outer side surface of the trench. A base contact region is in contact with part of the outer side surface of the trench, an upper part of the base layer, and an upper part of the source region. A source electrode is embedded in a remaining part of the trench and in contact with the source region and the base contact region.

Claim (Index 5):
The method according to  claim 1 , wherein\n the forming of the trench comprises forming a second insulating film on the front surface of the substrate, the second insulating film having an opening at a part in which the trench is formed, and the forming of the base contact region comprises obliquely ion implanting impurities to the inner side surface of the trench using the second insulating film as a mask.
