Abstract:
1. A method for fabricating a semiconductor package comprising: providing a semiconductor die comprising a circuit side, a plurality of die contacts on the circuit side, and an electrically insulating layer on the circuit side; forming a plurality of bumps on the die contacts; forming a polymer layer on the insulating layer and on the bumps; planarizing the polymer layer and the bumps; providing a substrate comprising a plurality of conductors comprising a plurality of first bonding pads and a plurality of second bonding pads; attaching the die to the substrate; bonding wires to the bumps and to the first bonding pads; forming a die encapsulant on the die with the polymer layer preventing physical contact between the die encapsulant and the circuit side; and forming a plurality of terminal contacts on the second bonding pads.
