Abstract:
A semiconductor device comprising:a semiconductor chip; a die pad having a surface on which the semiconductor chip is mounted; support leads formed in one piece with the die pad; bonding leads provided in a periphery of the die pad; and wires for connecting bonding pads of the semiconductor chip with the bonding leads, wherein the semiconductor chip, the die pad, the wires, and the support leads are sealed with a resin, protrusions are formed on the support leads on a same side as that of the die pad on which the semiconductor chip is mounted, and a distance between the surface of the die pad on which the semiconductor chip is mounted and tops of the protrusions is greater than a distance between the surface of the die pad on which the semiconductor chip is mounted and surfaces of the support leads on the same side as that of the die pad on which the semiconductor chip is mounted.
