Abstract
A semiconductor device includes a semiconductor chip mounted in a resin package body. A plurality of interconnection leads are provided on the resin package body along a lower edge thereof and project outwardly from the lower edge. A heat dissipation lead is connected to the resin package body for dissipating heat generated by the semiconductor chip. The heat dissipation lead includes a plate of a heat conducting material having a stage part and a heat sink part, wherein the stage part is held inside the resin package body and supports the semiconductor chip thereon. The heat sink part projects outwardly from the resin package body and includes a part that extends in a downward direction. The heat sink part has a lower edge that is formed at a level substantially flush with the outer lead part of the interconnection leads such that the semiconductor device is held upright, when placed on a substrate, by the outer lead part of the interconnection leads and by the lower edge of the heat sink part of the heat dissipation lead.
