Abstract:
1. A method of manufacturing a semiconductor device comprising the steps of: forming a gate electrode via a gate insulating film on a semiconductor substrate; forming source/drain extension regions in the semiconductor substrate using the gate electrode as a mask; forming carbon layers such that each of the carbon layers is offset from the front edge of the associated source/drain extension region in a direction away from the gate electrode; forming source/drain impurity diffusion regions such that each of the source/drain impurity diffusion regions is offset from the channel-side boundary of the associated carbon layer so as to be away from the gate electrode and is located shallower than the depth-direction boundary of the carbon layer; and forming a pocket region in the semiconductor substrate such that the associated source/drain extension region is located shallower than the pocket region, wherein the carbon layer is formed so as to be offset from the front edges of the pocket region and the source/drain extension region in the direction away from the gate electrode.
