Abstract

A lead bonding tool for bonding leads to respective semiconductor chip contacts. The bonding tool having a substantially flat bonding surface region with a depression therein. The depression allows the tool to grasp the lead during the bonding step and further facilitate the transmission of energy from the tool to the lead/contact interface to form the bond. Certain embodiments of the lead also have grooves and/or guides which are adapted to capture and better align the elongated lead sections with their respective chip contacts during the bonding step.
