Patent ID: 8247268

Claim:
A method of making a semiconductor device, comprising: providing a plurality of semiconductor die with a plurality of contact pads disposed over a first surface of the semiconductor die; forming a trench between the semiconductor die; depositing an insulating material in the trench; forming a plurality of conductive vias through the insulating material; forming a plurality of conductive traces over the first surface electrically connecting a first portion of the conductive vias to the contact pads; forming a redistribution layer (RDL) over a second surface of the semiconductor die opposite the first surface, the RDL extending across the second surface of the semiconductor die to route electrical signals to areas on the second surface including a central region of the semiconductor die, wherein a second portion of the conductive vias is electrically isolated from the conductive traces; and forming a repassivation layer over the second surface of the semiconductor die for electrical isolation between portions of the RDL.
