Patent ID: 8637341

Claim:
A method of manufacturing a semiconductor device, comprising: placing at least two semiconductor chips on a carrier, each chip having a first main surface with at least one contact pad and a second main surface with a plurality of contact pads, the second main surface of each semiconductor chip mounted on the carrier; covering the at least two semiconductor chips and the carrier with molding material; providing a recess to the first main surface of each of the at least two semiconductor chips, including to at least a portion of the at least contact pad, by removing a first portion of the molding material covering the first main surface of each of the at least two semiconductor chips; selectively removing portions of the molding material to form channels through the molding material to the carrier to selectively expose portions of the carrier; applying a first layer of conductive material over the molding material, wherein the first layer of conductive material fills the recess to each of the at least two semiconductor chips and electrically connects to the at least one contact pad thereon and fills the channels to cover the exposed portions of the carrier; removing the carrier; and singulating the at least two semiconductor chips such that for each of the at least two semiconductor chips, the first layer of conductive material extends from the at least one contact pad on the first main surface through at least one of the channels through the molding material, wherein a surface of the conductive material filling the channel is coplanar with the second main surface of the chip, so that a surface of the molding material, the second main surface of the semiconductor chip, including the plurality of contact pads thereon, and the at least one contact on first main surface of the semiconductor chip, represented by the conductive material filling the channel, form a common plane for mounting.
