Abstract
A semiconductor integrated circuit device includes a semiconductor substrate having a first surface and including an electrode on the first surface of the semiconductor substrate; a surface protecting film covering the first surface of the semiconductor substrate; an electrode underlayer on the surface protecting film, in electrical contact with the electrode; an external electrode on the surface protecting film, in electrical contact with the electrode underlayer, and having a substantially planar external surface; and a barrier part on the surface protecting a barrier against intrusion of moisture and ions into the semiconductor substrate, the barrier part having the same area as the semiconductor substrate and a substantially planar external surface.
