Abstract
Supporting leads extend from one side portion of a package to another side portion thereof and are arranged on both sides of an island such that both ends of the island are supported. An electrode for a fixing potential of a semiconductor chip is connected to these supporting leads by a bonding wire. One end of these supporting lead is located outside a column of an outer lead portion as the same structure as the outer lead portion. Thus, while a structure for commonly using each of the supporting leads as a lead for a fixing potential is adopted, a thermal distribution of the semiconductor chip can be uniformed and no island is inclined at a resin seal time.
