Method of fabricating stacked wire bonded semiconductor package with low profile bond line

摘要

A method of fabricating a low profile semiconductor package is disclosed including at least first and second stacked semiconductor die mounted to a substrate. The first and/or second semiconductor die may be fabricated with a plurality of redistribution pads formed over and electrically coupled to a plurality of bond pads. After the semiconductor die are formed and diced from the wafer, the die may be mounted to the substrate using a low profile reverse wire bond according to the present invention. In particular, a wedge bond may be formed between the wire and the redistribution pad without having to use a second wire bond ball on the die bond pad as in conventional reverse ball bonding processes.
