Abstract:
A semiconductor device comprising:a semiconductor chip of a rectangular shape with short and long sides having a main surface in which semiconductor elements and a plurality of bonding pads are formed, and a back surface opposite the main surface; a plurality of leads each having an inner part and an outer part, and including a plurality of first leads having inner end portions extended on the main surface of the semiconductor chip and a plurality of second leads having inner end portions terminating at a vicinity of the short sides of the semiconductor chip, the inner parts of the first leads extending across the long sides of the semiconductor chip and extending on the main surface of the semiconductor chip; bonding wires electrically connecting the bonding pads to the inner parts of the first leads; and a sealing member sealing the semiconductor chip, the inner parts of the leads and the bonding wires therein; wherein each of the inner parts of the second leads sealed in the sealing member has a bending portion falling substantially in a direction from the main surface toward the back surface of the semiconductor chip so that the inner end portions of the second leads are positioned relatively lower than the inner end portions of the first leads.
