Abstract:
Die are singulated from a wafer having a back layer by placing the wafer onto a first carrier substrate with the back layer adjacent the carrier substrate, forming singulation lines through the wafer to expose the back layer within the singulation lines, and using a plate structure to apply a pressure to the wafer to separate the back layer in the singulation lines. The pressure can be applied through the first carrier substrate proximate to the back layer, or can be applied through a second carrier substrate attached to a front side of the wafer opposite to the back layer.

Claim (Index 19):
A method of forming an electronic device 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 first and second opposing major surfaces, and wherein a layer of material is formed adjacent to the second major surface, and wherein the layer of material is placed adjacent to a first carrier substrate; forming singulation lines in the wafer through the spaces, wherein singulation lines terminate at least proximate to the layer of material; placing the wafer adjacent to a compressive layer; and moving a mechanical device in a direction generally parallel to adjacent one of the first major surface and the second major surface of the wafer to separate the layer of material in the singulation lines.
