Abstract:
1. A semiconductor integrated circuit device comprising: a first interlayer insulation film having a contact therein, the contact having an upper surface and including a void therein having an open upper portion; a plasma damage reduction unit including a lower electrode conformably on the void of the contact and on the upper surface of the contact, a dielectric film on the lower electrode, and an upper electrode on the dielectric film; and a second interlayer insulation film having an opening exposing an upper portion of the contact; wherein the lower electrode is conformably on a sidewall of the second interlayer insulation film; wherein a thickness of a portion of the dielectric film in the void is smaller than a thickness of a portion of the dielectric film on the upper surface of the contact; and wherein the thickness of the portion of the dielectric film in the void is smaller than a thickness of a portion of the dielectric film on the sidewall of the second interlayer insulation film.
