Patent number: 9673288Abstract: In a silicon carbide semiconductor device, a p-type SiC layer is disposed in a corner of a bottom of a trench. Thus, even if an electric field is applied between a drain and a gate when a MOSFET is turned off, a depletion layer in a pn junction between the p-type SiC layer and an n? type drift layer greatly extends toward the n? type drift layer, and a high voltage caused by an influence of a drain voltage hardly enters a gate insulating film. Hence, an electric field concentration within the gate insulating film can be reduced, and the gate insulating film can be restricted from being broken. In this case, although the p-type SiC layer may be in a floating state, the p-type SiC layer is formed in only the corner of the bottom of the trench. Thus, the deterioration of the switching characteristic is relatively low.Type: GrantFiled: April 17, 2013Date of Patent: June 6, 2017Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuichi Takeuchi, Kazumi Chida, Narumasa Soejima, Yukihiko Watanabe
