Abstract:
A method of manufacturing a resin sealing-type semiconductor device, comprising:providing a heat sink comp rising a first side, a second side generally perpendicular to the first side, and an arm portion extending from the second side;providing a lead frame having a first group of inner leads with a first group of front end portions and a second group of inner leads with a second group of front end portions;connecting the arm portion to the lead frame so that the first group of the front end portions and the second group of the front end portions are arranged so as to be parallel with the first side and the second side, respectively, yet are arranged so as not to overlap the front end portions of the first and second groups with the heat sink;bonding a semiconductor chip onto the heat sink; andconnecting the inner leads of the first and second groups to the semiconductor chip with a plurality of respective wires.
