Abstract: A photomask includes: a transparent substrate having a transparent property against exposing light; a first light-shielding pattern formed on the transparent substrate and having a first dimension; a second light-shielding pattern formed on the transparent substrate and having a second dimension larger than the first dimension; and an opening provided in part of the transparent substrate where the first light-shielding pattern and the second light-shielding pattern are not formed. The first light-shielding pattern includes a first semi-light-shielding portion and an auxiliary pattern which is arranged within the first semi-light-shielding portion and allows the exposing light to pass through in an opposite phase with respect to the first semi-light-shielding portion. The second light-shielding pattern includes a second semi-light-shielding portion and a light-shielding portion which does not substantially allow the exposing light to pass through.

Abstract: After a gate insulating film, a gate electrode and an on-gate protective layer have been formed in this order on an Si substrate, lightly-doped source/drain regions are formed in the substrate. First and second sidewalls are formed on the sides of the gate electrode and then heavily-doped source/drain regions are formed by implanting dopant ions using these sidewalls as a mask. After the second sidewall has been selectively removed, pocket implanted regions are formed and an overall protective film is deposited. Thereafter, an interlevel dielectric film is deposited, contact holes are formed to reach the heavily-doped source/drain regions and then plug electrodes are formed. Since the second sidewall has already been removed when the overall protective film is deposited, the gap between adjacent gate electrodes is not completely filled in.
