Abstract:
1. A method of making a semiconductor device, comprising: providing a carrier; mounting a plurality of semiconductor die to the carrier; forming a die extension region including a polymer material around a periphery of the semiconductor die; forming a plurality of rows of vias through the die extension region; depositing conductive material in the rows of vias; forming a first conductive layer between contact pads over an active surface of the semiconductor die and the rows of conductive vias; forming a second conductive layer over a back surface of the semiconductor die, opposite the active surface, electrically connected to the rows of conductive vias; forming an interconnect structure over the back surface of the semiconductor die electrically connected to the second conductive layer; and singulating between the rows of the conductive vias in the die extension region to separate the semiconductor die.
