Claim:
1. A method of singulating die from a wafer comprising: 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 disposed along the second major surface; placing the wafer onto a first carrier substrate, wherein the layer of material is adjacent the first carrier substrate; singulating the wafer through the spaces to form singulation lines while the wafer is coupled to the first carrier substrate, wherein the singulation lines terminate before penetrating completely through the layer of material; placing a substrate adjacent the first major surface, wherein the wafer is interposed between the substrate and the first carrier substrate; and moving a mechanical device along the substrate to separate the layer of material in the singulation lines.
