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 5):
A manufacturing method of a semiconductor device, comprising the steps of:\n (a) preparing a semiconductor substrate; (b) forming an insulating film portion over a principal surface of the semiconductor substrate; (c) forming a conductive film over the insulating film portion; and (d) patterning the conductive film and the insulating film portion to form 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 step (b) includes the steps of (b1) forming a first insulating film containing silicon and oxygen over the principal surface of the semiconductor substrate, (b2) forming a second insulating film containing silicon and nitrogen over the first insulating film, (b3) forming a third insulating film containing silicon and oxygen over the second insulating film, (b4) forming a fourth insulating film containing silicon and nitrogen over the third insulating film, and (b5) forming a fifth insulating film containing silicon and oxygen over the fourth insulating film, wherein the insulating film portion is formed by the first insulating film, the second insulating film, the third insulating film, the fourth insulating film, and the fifth insulating film by the steps (b1), (b2), (b3), (b4), and (b5), wherein the second insulating film includes an underlying insulating film and an upper insulating film, and wherein in the step (b3), at least a portion of the upper insulating film is oxidized to form the third insulating film.
