Abstract:
An insulating film and another insulating film are formed over a semiconductor substrate in that order to cover first, second, and third gate electrodes. The another insulating film is etched back to form sidewall spacers over side surfaces of the insulating film. Then, the sidewall spacers over the side surfaces of the insulating films corresponding to the sidewalls of the first and second gate electrodes are removed to leave the sidewall spacers over the side surfaces of the insulating film corresponding to the sidewalls of the third gate electrode. Then, the sidewall spacers and the insulating films are etched back, so that the sidewall spacers are formed of the insulating film over the sidewalls of the first, second, and third gate electrodes.

Claim (Index 1):
A manufacturing method of a semiconductor device, comprising the steps of:\n (a) providing a semiconductor substrate; (b) forming a first gate electrode via a first gate insulating film and a second gate electrode via a second gate insulating film over the semiconductor substrate; (c) forming first sidewall insulating films selectively formed on side surfaces of the first and second gate electrodes; (d) forming a first insulating film over the semiconductor substrate to cover upper surfaces of the first and second gate electrodes and side surfaces of the first sidewall insulating films, the first insulating film having first portions on upper surfaces of the first and second gate electrodes and second portions on side surfaces of the first sidewall insulating films on the first and second gate electrode; (e) forming second sidewall insulating films selectively formed on the second portions at the side surfaces of the second gate electrode; (f) forming a second insulating film over the first insulating film and the second sidewall insulating film; and (g) after the step (e), etching back the second insulating film, the second sidewall insulating films and the first insulating film to thereby form third sidewall insulating films having a first width which are formed on the side surfaces of the first gate electrode via the first sidewall insulating films and fourth sidewall insulating films having a second width which are formed on the side surfaces of the second gate electrode via the first sidewall insulating films, wherein the first width is smaller than the second width.
