Abstract:
A power device having a multi-chip package structure in which a transistor, which is a switching device, and a control IC chip, which is a driving device, are mounted together in a package, the power device comprising:a lead frame having a chip pad, an inner lead and an outer lead; a transistor chip, which is a switching device, attached on the chip pad of the lead frame by a conductive adhesive; a control integrated circuit (IC) chip, which is a driving device, attached on the chip pad of the lead frame at the side of the transistor chip by an insulating adhesive tape; a first gold wire for connecting a bond pad of the transistor chip and a bond pad of the control integrated circuit chip; a plurality of second gold wires for connecting a bond pad of the transistor chip to the inner lead of the lead frame and a bond pad of the control integrated circuit chip to the inner lead of the lead frame; and a molding means for molding the chip pad of the lead frame, inner lead, control integrated circuit chip, and first and second gold wires.
