Abstract:
A semiconductor device including a channel region formed in a semiconductor substrate; a source region formed on one side of the channel region; a drain region formed on the other side of the channel region; a gate electrode formed on the channel region with a gate insulating film therebetween; and a stress-introducing layer that applies stress to the channel region, the semiconductor device having a stress distribution in which source region-side and drain region-side peaks are positioned between a pn junction boundary of the channel region and the source region and a pn junction boundary of the channel region and the drain region.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor substrate with a surface; a channel region in a the semiconductor substrate; a gate electrode over the channel region and the surface of the semiconductor substrate; a gate insulating film between the gate electrode and the channel region; a source region in the semiconductor substrate at a source side of the channel region and a drain region in the semiconductor substrate at a drain side of the channel region; a first stress-introducing layer in the semiconductor substrate, the source region and the drain region being between the first stress-introducing layer and the surface of the semiconductor substrate; a second stress-introducing layer; and a first side-wall insulating film between the second stress-introducing layer and the gate electrode, the first side-wall insulating film having a first side positioned proximate to the second stress-introducing layer and a second side positioned proximate to the gate electrode, wherein,\n in the gate length direction in the cross section, the source region and the drain region are within the first stress-introducing layer, and \n in the gate length direction in the cross section, ends of the first stress-introducing layer are positioned inward of outer ends of the first side-wall insulating layer.
