Abstract:
1. A semiconductor device comprising: a gate insulating film formed on a semiconductor region of a first conductivity type; a gate electrode formed on the gate insulating film; extended doped layers of a second conductivity type formed in the semiconductor region under sides of the gate electrode; pocket doped layers of the first conductivity type formed in the semiconductor region under and in contact with the extended doped layers; sidewalls formed on lateral faces of the gate electrode; and source/drain doped layers of the second conductivity type formed in the semiconductor region alongside the respective sidewalls, wherein: the extended doped layers and the pocket doped layers are provided in an inside of a carbon-containing region on both sides of the gate electrode, and ions of carbon are doped in regions directly under only the sidewalls and side portions of the gate electrode.
