Abstract:
1. A semiconductor device comprising: a chip mounting portion; a plurality of leads arranged around the chip mounting portion; a plurality of suspending leads for supporting the chip mounting portion; a semiconductor chip mounted over the chip mounting portion via a die bonding material; and a plurality of wires electrically connecting a plurality of pads formed on a main surface of the semiconductor chip with the leads; wherein each of the suspending leads has a bent portion; wherein a first metal film is formed over a part of each of the suspending leads including the bent portion; wherein each first metal film has one end and another end portion opposite to the one end portion; wherein the one end portion is positioned closer to the chip mounting portion side than the another end portion; wherein a second metal film is formed over a part of each of the leads; wherein a thickness of the one end portion of each first metal film is less than that of each second metal film; and wherein the semiconductor chip is mounted over the chip mounting portion such that the one end of each of the metal plating films formed over the suspending leads is overlapped with the semiconductor chip.
