Semiconductor device

Abstract

A semiconductor device, includes: a first semiconductor chip including a first semiconductor substrate; and a second semiconductor chip including a second semiconductor substrate, wherein the first semiconductor substrate has a first substrate main surface and a first substrate back surface facing opposite directions in a first direction, and includes a first region and a second region disposed on the first substrate main surface, wherein the first semiconductor chip includes: a first MOSFET of a first type structure formed to include the first region; and a control circuit formed to include the second region, wherein the second semiconductor chip includes a second MOSFET of a second type structure formed to include the second semiconductor substrate, and wherein the second type structure is different from the first type structure.
