摘要:
The invention relates to a trench MOSFET with drain (8), sub-channel region (10) body (12) and source (14). The sub-channel region is doped to be the same conductivity type as the body (12), but of lower doping density. A field plate electrode (34) is provided adjacent to the sub-channel region (10) 10 and a gate electrode (32) next to the body (12).
