Patent ID: 8188583

Claim:
A semiconductor device comprising: a semiconductor chip having a first main surface, a plurality of electrodes formed on the first main surface, and a first back surface on the opposite side of the first main surface; a plurality of leads arranged around the semiconductor chip; a bonding wire that electrically couples the leads and the electrodes, respectively; a chip mounting part having a second main surface on which the semiconductor chip is mounted and a second back surface on the opposite side of the second main surface; a frame body part having a third main surface facing in the same direction as that of the second main surface and a third back surface on the opposite side of the third main surface, and arranged between the chip mounting part and the lead so as to surround the chip mounting part; a plurality of suspension leads linked to the outer edge of the frame body part; and a sealing body that seals the semiconductor chip, the bonding wire, the chip mounting part, the frame body part, the suspension lead, and part of the lead, wherein the chip mounting part is located immediately under the semiconductor chip and has a first part smaller than the outer shape of the semiconductor chip and a plurality of second parts that connect the first part and the inner edge of the frame body part, and wherein the second main surface of the first part and the second main surface of the second part of the part in opposition to the first back surface of the semiconductor chip are bonded to the first back surface of the semiconductor chip in their entire surfaces with an adhesive.
