Abstract:
1. A semiconductor device, comprising: a die pad comprised of a metal, and having at least one cutout portion in its peripheral edge portion, and a protruding portion formed by the cutout portion so as to protrude laterally from the peripheral edge portion; a first inner lead having at its end a bonding pad that is placed in the cutout portion with an interval between the bonding, pad and the die pad; a semiconductor chip held on the die pad so that a center position of the semiconductor chip is located on the protruding portion side with respect to a center position of the die pad; and a wire configured to electrically connect the semiconductor chip to the bonding pad, wherein the bonding pad has a first extended portion extending along a side surface of the die pad with an interval therebetween, the side surface of the die pad extends from the cutout portion in a first direction, the die pad further includes a suspension lead extending from the protruding portion, a width of the protruding portion is greater than a width of the suspension lead, the semiconductor chip is disposed on at least a portion of the protruding portion, and in a plan view, a length of the first extended portion in the first direction is greater than a length of the side surface of the die pad in the first direction.
