A wire bond interconnection between a die pad and a bond finger includes a support pedestal at a bond site of the lead finger, a ball bond on the die pad, and a stitch bond on the support pedestal, in which a width of the lead finger at the bond site is less than a diameter of the support pedestal. Also, a semiconductor package including a die mounted onto and electrically connected by a plurality of wire bonds to a substrate, in which each of the wire bonds includes a wire ball bonded to a pad on the die and stitch bonded to a support pedestal on a bond site on a lead finger, and in which the width of the lead finger at the bond site is less than the diameter of the support pedestal.
A wire bond interconnection between a die pad and a lead finger, comprising a support pedestal at a bond site of the lead finger between the wire and the lead finger, the support pedestal being formed around a top and sides of the lead finger and being in direct contact with the lead finger, a ball bond on the die pad, and a stitch bond having the wire being metallurgically bonded directly to the support pedestal.
