Original Abstract Submitted
A semiconductor device includes a semiconductor substrate, trenches extending in a first direction and arranged at intervals in a second direction intersecting the first direction, a gate insulating film, and a gate electrode. The semiconductor substrate includes a source region, a body region, a drift region, bottom regions, electric field relaxation regions, and contact regions. There are overlapping ranges in which each of inter-trench semiconductor regions and each of the electric field relaxation regions overlap each other, the overlapping ranges include contact overlapping ranges in which the contact regions are disposed and non-contact overlapping ranges in which the contact regions are not disposed, and the contact overlapping ranges and the non-contact overlapping ranges are alternately arranged in the first direction.
