摘要:
A semiconductor device includes: an n type drain region; an n type drift region that connects with the n type drain region; a p type body region; a n type source region that connects with the p type body region; and a gate electrode that is provided, with being covered by a gate insulation film, in a gate trench that penetrates the p type body region. The semiconductor further includes: a p type silicon region that adjoins the n type drift region; and an n type silicon region provided in a region almost including a carrier passage that connects the n type drift region and the p type body region. Here, the p type silicon region and the p type body region directly connect with each other.
