A semiconductor device includes a first insulating layer and a second insulating layer in a trench. The first insulating layer insulates two MOSFETs from each other, and the second insulating layer has a true stress opposite to a true stress of the first insulating layer. The second insulating layer includes two regions of different true stresses. This enables a drain current flow in each MOSFET to be independently controlled in a semiconductor device that employs a STI method for element isolation.
