Patent number: 10615079Abstract: A buried n-type region is provided in a surface layer portion of an n-type body layer of a Pch MOSFET. This makes it possible to lower the threshold voltage Vt. In a portion of the n-type body layer other than the buried n-type region, since an n-type impurity concentration can be kept relatively high, the threshold voltage Vt can be lowered while securing an on-breakdown voltage. Furthermore, since an accumulation region is configured by an n-type active layer, a partial high concentration portion is not formed in a p-type drift layer. Therefore, as in the case where the partial high concentration portion is generated in the p-type drift layer, a reduction in a breakdown voltage caused by an electric field concentration can be restricted from occurring with a distribution in which equipotential lines are concentrated.Type: GrantFiled: March 13, 2017Date of Patent: April 7, 2020Assignee: DENSO CORPORATIONInventors: Shogo Ikeura, Yusuke Nonaka, Shinichirou Yanagi, Seiji Noma, Shinya Sakurai
