Abstract: A semiconductor device has a plurality of conductive vias formed into a semiconductor wafer. A portion of the semiconductor wafer is removed so the conductive vias extend above a surface of the semiconductor wafer. A notch is formed in the semiconductor wafer around each of the conductive vias. The notch around the conductive vias can be formed by wet etching, dry etching, or LDA. A first insulating layer is formed over a surface of the semiconductor wafer and conductive vias and into the notch to provide stress relief between the conductive vias and semiconductor wafer. A portion of the first insulating layer is removed to expose the conductive vias. A first conductive layer and second insulating layer can be formed around the conductive vias. A second conductive layer can be formed over the conductive vias. The notch can extend into the second insulating layer.

Abstract: A semiconductor device has a substrate including a plurality of conductive vias formed vertically and partially through the substrate. An encapsulant is deposited over a first surface of the substrate and around a peripheral region of the substrate. A portion of the encapsulant around the peripheral region is removed by a cutting or laser operation to form a notch extending laterally through the encapsulant to a second surface of the substrate opposite the first surface of the substrate. A first portion of the substrate outside the notch is removed by chemical mechanical polishing to expose the conductive vias. A second portion of the substrate is removed by backgrinding prior to or after forming the notch. The encapsulant is coplanar with the substrate after revealing the conductive vias. The absence of an encapsulant/base material interface and coplanarity of the molded substrate results in less over-etching or under-etching and fewer defects.
