Patent ID: 8581396

Claim:
A semiconductor device comprising: a semiconductor chip having an obverse surface, a reverse surface opposite the obverse surface, and a plurality of electrodes formed on the obverse surface thereof; a frame member having a first portion for mounting the semiconductor chip, a second portion formed to surround the first portion, a plurality of suspension leads each connected to the second portion, a plurality of leads disposed around the semiconductor chip and outside of the second portion, the first portion having a first area which is capable of mounting the semiconductor chip in a plan view, the second portion having a second area which is capable of providing a wire connection; a plurality of first wires connecting selected first ones of the plurality of electrodes of the semiconductor chip with the plurality of leads of the frame member; and a sealing body sealing the semiconductor chip, the plurality of first wires, a part of each of the plurality of leads, and a part of each of the first and second portions of the frame member, wherein the semiconductor chip is mounted over the first area of the first portion of the frame member, wherein the frame member has a slit which is formed between the first and second portions, wherein the slit has a first slit which extends along an outer peripheral edge of the first portion, and a second slit which extends from the first slit toward the second portion.
