Abstract

A semiconductor device with plated pillars and leads is disclosed and may include a semiconductor die comprising a conductive pillar, a conductive lead electrically coupled to the conductive pillar, a metal plating layer covering the conductive lead and conductive pillar, and an encapsulant material encapsulating the semiconductor die and at least a portion of the plating layer. The pillar, lead, and plating layer may comprise copper, for example. The plating layer may fill a gap between the pillar and the lead. A portion of the metal plating layer may, for example, comprise an external lead. The metal plating layer may cover a side surface of the pillar and a top surface, side surface, and at least a portion of a bottom surface of the lead. The metal plating layer may cover side and bottom surfaces of the pillar and top, side, and at least a portion of bottom surfaces of the conductive lead.
