摘要：
A low profile semiconductor package is disclosed including at least first and second stacked semiconductor die mounted to a substrate. The first semiconductor die may be electrically coupled to the substrate with a plurality of stitches in a forward ball bonding process. The second semiconductor die may in turn be electrically coupled to the first semiconductor die using a second set of stitches bonded between the die bond pads of the first and second semiconductor die. The second set of stitches may each include a lead end having a stitch ball that is bonded to the bond pads of the second semiconductor die. The tail end of each stitch in the second set of stitches may be wedge bonded directly to lead end of a stitch in the first set of stitches.
