Abstract:
In a MONOS memory having an ONO film, dielectric breakdown and a short circuit are prevented from occurring between the end of the lower surface of a control gate electrode over the ONO film and a semiconductor substrate under the ONO film. When a polysilicon film formed over the ONO film ON is processed to form the control gate electrode, the ONO film is not processed. Subsequently, a second offset spacer covering the side surface of the control gate electrode is formed. Then, using the second offset spacer as a mask, the ONO film is processed. This results in a shape in which in the gate length direction of the control gate electrode, the ends of the ONO film protrude outwardly from the side surfaces of the control gate electrode, respectively.

Claim (Index 12):
The semiconductor device according to  claim 11 , further comprising:\n a first sidewall covering the side surface of the first gate electrode via the first offset spacer; a second sidewall covering the side surface of the second gate electrode via the second offset spacer; and a dented part formed at the top surface of the semiconductor substrate immediately under the second sidewall, wherein the position of the bottom surface of the dented part is lower than the position of the top surface of the semiconductor substrate immediately under the first sidewall, and wherein the film thickness of the third insulation film is smaller than the film thickness of the first insulation film.
