ABSTRACT:
A semiconductor apparatus is disclosed. The semiconductor apparatus comprises a gate electrode formed on a surface of a semiconductor substrate with a gate insulating film provided therebetween. The semiconductor apparatus further comprises a gate sidewall insulating film having a three-layered structure formed of a first nitride film, an oxide film, and a second nitride film, which are formed on a sidewall of an upper portion of the gate electrode, and a gate sidewall insulating film having a two-layered structure formed of the oxide film and the second nitride film, which are formed on a sidewall of a lower portion of the gate electrode. The semiconductor apparatus further comprises a raised source/drain region formed of an impurity region formed in a surface layer of the semiconductor substrate and an impurity region grown on the impurity region.
