Abstract:
To improve the performance of a semiconductor device, the semiconductor device includes an insulating film portion over a semiconductor substrate. The insulating film portion includes an insulating film containing silicon and oxygen, a first charge storage film containing silicon and nitrogen, an insulating film containing silicon and oxygen, a second charge storage film containing silicon and nitrogen, and an insulating film containing silicon and oxygen. The first charge storage film is included by two charge storage films.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor substrate; an insulating film portion formed over a principal surface of the semiconductor substrate; a conductive film formed over the insulating film portion; a gate electrode included by the conductive film; and a gate insulating film included by the insulating film portion between the gate electrode and the semiconductor substrate, wherein the insulating film portion includes a first insulating film that is formed over the principal surface of the semiconductor substrate and contains silicon and oxygen, a second insulating film that is formed over the first insulating film and contains silicon and nitrogen, a third insulating film that is formed over the second insulating film and contains silicon and oxygen, a fourth insulating film that is formed over the third insulating film and contains silicon and nitrogen, and a fifth insulating film that is formed over the fourth insulating film and contains silicon and oxygen, and wherein the second insulating film includes an underlying insulating film and an upper insulating film.
