Abstract:
1. A process for making an integrated circuit package comprising: providing a substrate having a chip-attaching surface; applying an A-stage liquid paste on the chip-attaching surface of the substrate, the A-stage liquid paste including a thermosetting material and a solvent; heating the substrate to remove the solvent of the A-stage liquid paste in a manner that the A-stage liquid paste is transformed into a dry B-stage film layer; attaching a chip to the chip-attaching surface of the substrate using the B-stage film layer as an adhesive, the B-stage film layer being maintained in a partially cured condition; electrically connecting the chip with the substrate having the B-stage film layer; and forming a molding compound on the chip-attaching surface of the substrate, a packing pressure for the molding compound being larger than a chip-attaching pressure in a manner that the B-stage film layer re-bonds to the chip to improve effective chip-bonding area.
