Abstract:
A dual-chip integrated circuit package, which comprises:a leadframe having a first set of leads arranged at one side of the leadframe, and a second set of leads arranged at an opposite side with respect to the first set of leads, allowing the first set of leads to be spaced apart from the second set of leads by a spacing, wherein each of the first and second sets of leads is defined into an inner part and an outer part, with the spacing being formed between the inner part of the first set of leads and the inner part of the second set of leads, and wherein the inner part of the first set of leads is greater in length that the inner part of the second set of loads, and the inner part of the first set of leads has a first side formed with a chip attach area and a second side opposite the first side; a first integrated circuit chip having a first side where at least one row of bonding pads are formed and a second side insulatively attached to the chip attach area on the first side of the inner part of the first set of leads, wherein the first integrated circuit chip does not extend over the spacing between the inner parts of the first and second sets of leads; a second integrated circuit chip having a first side where one row of bonding pads are formed, with the first side being insulatively partially attached to the second side of the inner part of the first set of leads in such a manner that the bonding pads on the second integrated circuit chip are positioned in the spacing; a first set of bonding wires for electrically connecting the bonding pads on the first integrated circuit chip to a selected part of the leads of the leadframe; a second set of bonding wires for electrically connecting the bonding pads on the second integrated circuit chip to a selected part of the leads of the leadframe; and an encapsulant for encapsulating the first integrated circuit chip, the second integrated circuit chip, the first set of bonding wires, the second set of bonding wires, the inner part of the first set of leads, and the inner part of the second set of leads.
