Abstract:
Methods of dicing semiconductor wafers are described. In an example, a method of dicing a wafer having a plurality of integrated circuits thereon involves dicing the wafer into a plurality of singulated dies disposed above a dicing tape. The method also involves forming a material layer over and between the plurality of singulated dies above the dicing tape. The method also includes expanding the dicing tape, wherein a plurality of particles is collected on the material layer during the expanding.
