ABSTRACT:
An inexpensive low contact resistance electrical bonding interconnect having a metal bond pad portion and conductive epoxy portion. The conductive epoxy portion comprises a metal oxide reducing agent for reducing oxides formed before and/or during the fabrication of the bonding interconnect. The bonding interconnect is used to bond a die pad to a supporting substrate thereby forming a surface mount device.
