Patent ID: 7452747

Claim:
A method for assembling a semiconductor package comprising: providing a wafer including a front surface and an opposing back surface, and a plurality of semiconductor dies disposed on the front surface of the wafer, wherein each semiconductor die includes an active surface with a plurality of die contact areas; forming mushroom-shaped precursor conducting members on the die contact areas via an electro-plating technique, the mushroom-shaped precursor conducting members having a substantially rod-shaped lower portion and a rounded upper portion that is laterally larger than the lower portion; coating the front surface of the wafer and at least a base portion of each of the precursor conducting members with an electrically insulating layer; heating the wafer to form conducting members from the precursor conducting members; attaching a tape to upper surfaces of the conducting members and to an upper surface of the electrically insulating layer; thinning the back surface of the wafer; removing the tape; and separating individual semiconductor dies from the wafer.
