ABSTRACT:
A semiconductor device of the present invention accommodates a large semiconductor chip in a downsized package without impairing its reliability. The semiconductor chip is bonded on a relatively small die pad. Common inner leads and a plurality of inner leads are disposed opposite and spaced from the semiconductor chip by a gap ranging from 0.1 mm to 0.4 mm and the gap between the semiconductor chip and the common inner leads and the plurality of inner leads is filled with a resin which forms pan of a resin package.
