Dual-chip integrated circuit package and method of manufacturing the same

Abstract

A dual-chip integrated circuit package and a method for manufacturing such a dual-chip integrated circuit package are proposed, which can help prevent the occurrence of cracking and delamination in the chips and the occurrence of voids in the encapsulant during the manufacture process. The dual-chip integrated circuit package is constructed on a leadframe having a plurality of first leads and a plurality of second leads and at least a pair of support members between the first and second leads. Further, the dual-chip integrated circuit package includes at least one support member attached to the front side of the first integrated circuit chip for providing a support to the bonding pads on the second integrated circuit chip; the support member being not smaller in dimension than the area where the bonding pads on the second integrated circuit chip are located. An encapsulant is used for encapsulating the first integrated circuit chip, the second integrated circuit chip, the support members, and inner parts of the first and second leads of the leadframe. Since the support members can provide good support to the bonding pads on the second integrated circuit chip, it can help prevent the chips from being cracked during the manufacture process. The manufactured dual-chip integrated circuit package can be thus reliable in quality.
