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 20):
The method of  claim 19  further comprising:\n placing the wafer onto a second carrier substrate, wherein the layer of material is opposite to the second carrier substrate; and \n cooling at the least the first carrier substrate during at least a portion of the step of moving the mechanical device, wherein:\n providing the wafer comprises providing the layer of material comprising one of a metal layer, a wafer backside coating, or a die attach film; and \n placing the wafer adjacent to the compressive layer comprises placing the second carrier substrate so that the first carrier substrate contacts the compressive layer.
