Claim:
1. A device, comprising: an integrated circuit chip including a backside surface defining a backside plane; a plurality of wire bonds conductively coupled to the integrated circuit chip, the wire bonds individually having a first end connected to the integrated circuit chip and a second end at the backside plane, the second end defining a conductive exposed portion that is an integrally formed part of the wire bond, wherein the first end is opposite the second end; an encapsulant material encasing at least portions of (a) the integrated circuit chip and (b) the wire bonds, wherein the backside surface of the integrated circuit chip at the backside plane and the second ends of the wire bonds at the backside plane are exposed through the encapsulant material, and the encapsulant material has a mechanically altered bottom surface at the backside plane extending between the second ends of the wire bonds and the backside surface of the integrated circuit chip; a conductive structure including a plurality of bond pads spaced from the second ends of the wire bonds; and a plurality of conductive balls conductively coupling the wire bonds to the conductive structure, the conductive balls individually including a first side directly attached to a second end of a wire bond at the backside plane and a second side directly attached to a corresponding bond pad of the conductive structure.
