Abstract:
A method for making a semiconductor package with stacked dies, the method comprising:providing a substrate having a first semiconductor die mounted thereon; stacking a second semiconductor die on top of the first die; electrically connecting conductive wires between wire bonding pads on respective top surfaces of the first die, the second die, and the substrate; attaching a bottom surface of the second die to the top surface of the first die with a first layer of an adhesive such that the bottom surface of the second die is supported above the conductive wires connected to the wire bonding pads on the first die without contacting the wires, and such that the adhesive covers the wire bonding pads on the first die; dispensing a bead of an adhesive around the periphery of the first and second dies and onto the substrate such that the bead of adhesive covers the bonding pads on the top surface of the second die, ends of the conductive wires connected thereto, and the entire length of the conductive wires extending between the periphery of the dies and the substrate; curing the first layer and bead of adhesive to harden them; and, molding a monolithic body of an encapsulant over the first and second dies and the bead of adhesive.
