Patent ID: 8450151

Claim:
A method of packaging integrated circuits: mounting a multiplicity of dice on a plastic carrier, wherein each of the dice includes a plurality of I/O pads having wire bonded contact studs secured thereto; covering the dice with an encapsulant material to form an encapsulant carrier structure wherein the encapsulant material is applied by one of screen printing and stencil printing; grinding a first surface of the encapsulant and the contact studs such that exposed portions of the contact studs are smooth and substantially co-planar with the first surface of the encapsulant; forming a conductive redistribution structure over the encapsulant carrier structure, wherein at least some of the contact studs are in electrical communication with the conductive redistribution structure, the conductive redistribution structure including a plurality of solder pads, each of the solder pads being electrically connected to an associated contact stud, wherein at least some of the solder pads have centers that are offset relative to the centers of their associated contact studs; creating solder bumps on the solder pads; and applying a second encapsulant layer over the encapsulant carrier structure that embeds at least portions of the contact bumps and covers the redistribution structure.
