WebProcessing Conditions. As stated above, it is generally advisable to dice thin wafers with an extremely fine-grit blade. But because these blades have reduced cutting power, they can be affected by films, TEGs, and other elements of the wafer frontside. Clogging can result, in turn compromising processing quality on the wafer backside. Webin dicing processes and blade design allow for dicing of these wafers with minimum mechanical damage to the dice. Achieving end cut with no damage requires a fine balance between the design of the saw street dimension, the contents in the street and the wafer level processing that introduces internal stresses into the wafer.

Webdicing of wafers requires experience, judgment, and high-performance equipment [4]. Successful sawing requires selecting the correct saw blade from dozens of possibilities and finding the proper combination among dozens of control settings. The wrong blade or the wrong combination of parameters can damage the wafer.
