A plastic packaged semiconductor device is constructed by sealing, with a sealing plastic, a semiconductor chip which has an electrode pad arranged in a central portion of an upper surface, a die pad to which the semiconductor chip is die-bonded, bonding wires which are connected to the electrode pad, and inner leads which are arranged in close vicinity of the die pad and have tip portions having upper flat surfaces which are positioned at a level equal to or higher than the upper surface of the semiconductor chip and to which the bonding wires are connected. Accordingly, the small thin plastic packaged semiconductor device in which the bonding wires do never come into contact with the edge of the semiconductor chip can be achieved.
