Abstract:
A semiconductor device whose performance is improved is disclosed. In the semiconductor device, an offset spacer formed in a memory cell is formed by a laminated film of a silicon oxide film and a silicon nitride film, and the silicon oxide film is particularly formed to directly contact the sidewall of a memory gate electrode and the side end portion of a charge storage film; on the other hand, an offset spacer formed in a MISFET is formed by a silicon nitride film. Particularly in the MISFET, the silicon nitride film directly contacts both the sidewall of a gate electrode and the side end portion of a high dielectric constant film.

Claim (Index 16):
A semiconductor device comprising a non-volatile memory cell and a field-effect transistor on a main surface of a semiconductor substrate,\n wherein the non-volatile memory cell comprises:\n a first insulating film formed over the main surface including a charge storage film; \n a first gate electrode formed over the first insulating film; and \n a first offset spacer formed over a side surface of the first gate electrode and including a silicon oxide film contacting the charge storage film, and wherein the field-effect transistor comprises: \n a second insulating film formed over the main surface containing a metal compound; \n a second gate electrode formed over the second insulating film; and \n a second offset spacer formed over a side surface of the second gate electrode and including a silicon nitride film contacting the second insulating film.
