Abstract:
A semiconductor device comprising:a semiconductor substrate; at least one electrode pad on a surface of the semiconductor substrate, the electrode pad containing aluminum; a passivation film covering a surface of the semiconductor substrate and a surface of the electrode pad and having an opening leading to the electrode pad, the passivation film containing an insulator selected from the group consisting of PSG and silicon nitride; a metal layer on the surface of the electrode pad at an area of the opening and on the passivation film near the opening, the metal layer containing Pd, Ni and Ti and having a thickness of about 4000 angstroms; a bump electrode in contact with the metal layer; and resin film covering a surface of the semiconductor substrate except at a top area of the bump electrode, the resin film having a thickness being at least about 20% of a thickness of said bump electrode.
