Abstract:
1. An insulated-gate field-effect transistor, comprising: a support substrate; a bar-shaped strained silicon layer on the support substrate; a gate insulator formed so as to spread across an upper surface of the bar-shaped strained silicon layer, in a direction orthogonal to a longitudinal direction of the bar-shaped strained silicon layer, and, covering at least a part of both sides of the bar-shaped strained silicon layer; a gate electrode formed on the gate insulator; and a source region and a drain region, placed in regions positioned on opposite sides of the gate electrode, respectively, and along the longitudinal direction of the bar-shaped strained silicon layer, wherein a channel is formed in a portion of the bar-shaped strained silicon layer, corresponding to a region on the underside of the gate electrode, in such a way as to extend along the longitudinal direction of the bar-shaped strained silicon layer.
