    摘要: A method for singulating semiconductor wafers is disclosed. A preferred embodiment comprises forming scrub lines on one side of the wafer and filling the scrub lines with a temporary fill material. The wafer is then thinned by removing material from the opposite side of the wafer from the scrub lines, thereby exposing the temporary fill material on the opposite side. The temporary fill material is then removed, and the individual die are removed from the wafer.
