Abstract
A semiconductor interconnection device having a semiconductor die, a plurality of epoxy bonds, and an array of insulating islands is disclosed. The semiconductor die has a plurality of conductive contacts. The plurality of epoxy bonds has a metallic substance such as silver. The epoxy bonds are configured to provide interconnection between the semiconductor die and an external structure. The plurality of epoxy bonds is selectively applied to the plurality of conductive contacts on the semiconductor die and corresponding conductive contacts on the external structure. The array of insulating islands is coupled to the plurality of conductive contacts. The islands are configured to prevent migration of the metallic substance from the plurality of epoxy bonds to the semiconductor die through the plurality of conductive contacts.
