Abstract:
A method for forming an electronic device includes providing a wafer having a plurality of die formed as part of the wafer and separated from each other by spaces. A layer of material is disposed atop a major surface of the wafer and the layer of material is placed adjacent to first carrier substrate comprising a first adhesive layer. The wafer is singulated through the spaces to form singulation lines. A second carrier substrate comprising a second adhesive layer is placed onto an opposite major surface of the wafer. The method includes moving a mechanical device adjacent to and in a direction generally parallel to one of the first carrier substrate or the second carrier substrate to separate the layer of material in the singulation lines. In one example, the second adhesive layer has an adhesive strength that is less than that of the first adhesive layer.

Claim (Index 9):
A method of singulating a wafer comprising:\n providing a wafer having a plurality of die formed as part of the wafer and separated from each other by spaces, wherein the wafer has a first major surface and a second major surface opposite to the first major surface, and wherein a layer of material is disposed atop the second major surface; placing the wafer and a first carrier substrate into contact with each other, wherein:\n the first carrier substrate comprises a first adhesive material, and \n the layer of material is disposed adjacent to the first adhesive material; \n singulating the wafer through the spaces to form singulation lines, wherein singulating includes stopping in proximity to the layer of material; placing the wafer and a second carrier substrate into contact with each other, wherein:\n the second carrier substrate comprises a second adhesive material having an adhesive strength that is different than that of the first adhesive material; \n the second adhesive material faces the wafer and laterally overlaps at least a portion of the wafer; and \n the wafer is interposed between the first carrier substrate and the second carrier substrate; and \n moving a mechanical device in a direction generally parallel to and adjoining one of the first carrier substrate or the second carrier substrate to separate the layer of material in the singulation lines.
