Abstract:
A method of forming a semiconductor assembly, comprising:providing a semiconductor device having a plurality of bond pads disposed thereon; placing a forming chuck having a raised forming portion adjacent a first surface of a sheet of conductive material having a plurality of lead members formed therein; aligning the raised forming portion with the plurality of lead members; placing a receiving chuck having a receiving portion adjacent a second surface of the conductive sheet substantially opposite from the forming chuck; aligning the receiving portion with the plurality of lead members, the receiving portion being shaped to receive at least part of the forming portion; compressing the forming chuck and the receiving chuck against the conductive sheet to bend the plurality of lead members into a plurality of pre-formed conductive leads; after compressing the plurality of lead members to form the plurality of pre-formed conductive leads, engaging the plurality of pre-formed conductive leads with the semiconductor device; and bonding the plurality of pre-formed conductive leads to corresponding bond pads on the semiconductor device.
