Patent ID: 7101737

Claim:
A method of manufacturing a microelectronic device having a microelectronic die including an integrated circuit and a plurality of bond-pads coupled to the integrated circuit, comprising: coupling the die to an interconnecting unit, the interconnecting unit having a substrate and a plurality of conductive features, the substrate having a first side and a second side, at least a set of the conductive features including a contact element, a conductive line connected to the contact element, and a ball-pad connected to the conductive line, the ball-pads being on the first side of the substrate, wherein the die is coupled to the interconnecting unit to electrically couple the bond-pads on the die with corresponding contact elements on the substrate, and wherein the contact elements define a cap-zone for encapsulation by a protective casing; encapsulating the die and the contact elements by engaging a first bearing surface of a first mold unit against the first side of the substrate, engaging a second bearing surface of a second mold unit against the second side of the substrate, positioning the die in the second mold unit, and injecting a molding compound into at least the second mold unit; and inhibiting the molding compound from leaking out of the cap-zone between the substrate and at least one of the first and second mold units by engaging a seal on the substrate with the one of the first and second mold units.
