Abstract:
A semiconductor device comprising:(a) a semiconductor substrate;(b) a gate insulating film formed on said semiconductor substrate;(c) a gate electrode formed on said gate insulating film;(d) insulating films formed on a sidewall of said gate electrode, each of said insulating films being L-shaped wherein said L-shaped insulating film makes contact with an end facet of said gate insulating film;(e) raised source and drain layers formed on said semiconductor substrate in selected areas so that said raised source and drain layers make contact with a part of said insulating films, said raised source and drain layers having a side surface and a top surface; and(f) a second insulating film formed on said insulating film, said second insulating film being in contact with said side surface of said raised source and drain layers, wherein said side surface is one of a (110) plane and a (111) plane.
