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 2):
The method for manufacturing a semiconductor device according to  claim 1 , further comprising the steps of:\n (b1) forming a third insulation film over the semiconductor substrate in a second region; and (c1) forming a second gate electrode over the third insulation film in the second region, wherein in the step (d), the second insulation film covering each of the side surfaces on the opposite sides of the first gate electrode in the gate length direction of the first gate electrode, and the side surfaces on the opposite sides of the second gate electrode in the gate length direction of the second gate electrode is formed, the method further comprising the steps of: (e1) performing etching using the second insulation film as a mask, and thereby processing the third insulation film; and (f1) performing ion implantation using the second insulation film as a mask, and thereby forming second source/drain regions at the top surface of the semiconductor substrate in the second region, wherein the second gate electrode and the second source/drain regions form a second transistor.
