Method of making a center bond flip chip semiconductor carrier

摘要

A center bond flip chip device carrier and a method for making and using it are described. The carrier includes a flexible substrate supporting a plurality of conductive traces. A cut out portion is formed in each trace at a position within a gap of a layer of elastomeric material provided over the traces. Each cut out portion is sized and configured to receive a solder ball for electrically connecting the carrier with a semiconductor die.
