Patent ID: 8796837

Claim:
A power device comprising: a substrate; a power semiconductor chip having an upper surface defining an upper surface plane, and a lower surface, the lower surface affixed to the substrate; encapsulating material surrounding the substrate and the power semiconductor chip; and a lead comprising a main portion, a raised portion, and an end portion, wherein the main portion is separated from the end portion by the raised portion, wherein the lead is a unitary piece of leadframe metal, the main portion extending from outside the encapsulating material to the power semiconductor chip and having a longitudinal axis, the longitudinal axis of the main portion being disposed parallel to the upper surface plane of the power semiconductor chip; the end portion is bonded to, and is in electrical contact with, a bonding pad on the upper surface of the power semiconductor chip; and at least part of the raised portion is positioned above the semiconductor chip at a greater height than each of the main portion and the end portion, wherein the end portion comprises a contact finger which includes a first contact region and a second contact region, wherein the first contact region makes electrical contact to the bonding pad at a first location on the bonding pad, wherein the second contact region makes electrical contact to the bonding pad at a second location on the bonding pad, and wherein the first contact region and the second contact region are separated by an intervening region which is not in physical contact with the bonding pad, and wherein the raised portion extends toward the end portion in a first direction, wherein the end portion includes a first finger that extends in a second direction, wherein the end portion further includes a second finger that extends parallel to the first finger, and wherein the first direction is substantially perpendicular to the second direction.
