Method of manufacturing a semiconductor device

Image Number 4 for United States Patent #8193060.

Provided is a method for manufacturing a semiconductor device. A well region formed on a semiconductor substrate includes a plurality of trench regions, and a source electrode is connected to a source region formed on a substrate surface between the trench regions. Adjacently to the source region, a high concentration region is formed, which is brought into butting contact with the source electrode together with the source region, whereby a substrate potential is fixed. A drain region is formed at a bottom portion of the trench region, whose potential is taken to the substrate surface by a drain electrode buried inside the trench region. An arbitrary voltage is applied to a gate electrode, and the drain electrode, whereby carriers flow from the source region to the drain region and the semiconductor device is in an on-state.
