1. A lead frame for a multi-chip package mounted with two semiconductor chips, the lead frame comprising:

  • a frame;

    two die pads differing in size and mounting thereon the semiconductor chips respectively;

    suspension leads supporting the die pads to the frame;

    a die pad connecting portion connecting the die pads; and

    leads supported to the frame and connected to terminals formed on the semiconductor chips by means of metal wires, whereinone of the two die pads and the die pad connecting portion are arranged to satisfy a positional relationship that a main plane center line of the one die pad deviates by a given distance from a main plane center line of a resin molding area, the main plane center line of the resin molding area passing the two die pads, and that a main plane center line of the die pad connecting portion is aligned with the main plane center line of the resin molding area or located on an opposite side to the main plane center line of the one die pad with respect to the main plane center line of the resin molding area.
