Patent ID: 7812398

Claim:
A semiconductor device including a p-type field-effect transistor, comprising: a semiconductor substrate; a BOX layer formed on the semiconductor substrate; a SOI layer formed so as to extend on the BOX layer in a first direction, with a plane direction of an upper surface and side surface being a (100) surface; a gate electrode formed on a pair of side surfaces parallel to the first direction and an upper surface of the SOI later via a gate insulating film and extending in a <010> direction of the SOI layer; a channel formed in the SOI layer under the gate electrode, in which a current flows in a <110> direction of the SOI layer; and an insulating film having a tensile strain, formed on the BOX layer, the side surfaces of the SOI layer, the upper surface of the SOI layer, and an upper surface of the gate electrode successively.
