Patent ID: 7569917

Claim:
A semiconductor device comprising: a semiconductor chip having a first face and an edge; an insulating base film which has a semiconductor chip mounting face, the semiconductor chip mounting face facing the first face of the semiconductor chip with predetermined spacing; a plurality of first projecting electrodes formed in a first row on the first face of the semiconductor chip along the edge of the semiconductor chip; a plurality of second projecting electrodes formed in a second row on the first face of the semiconductor chip along the edge of the semiconductor chip, the plurality of second projecting electrodes being located between the edge of the semiconductor chip and the first row of first projecting electrodes, and a height of said second projecting electrode being smaller than a height of said first projecting electrode; a plurality of first inner leads extending on the semiconductor chip mounting face of the base film such that the plurality of first inner leads reach said plurality of first projecting electrodes respectively: an insulating film between the first inner leads and the first face of the semiconductor chip; and a plurality of second inner leads extending between the insulating film and the first face of the semiconductor chip such that the plurality of second inner leads reach said plurality of second projecting electrodes respectively, wherein the first and second inner leads are disposed on the same side of the insulating base film.
