  • Publication number: 20210296176
    Abstract: A method for singulating a semiconductor wafer includes providing the semiconductor wafer having a plurality of semiconductor devices adjacent to a first surface, the plurality of semiconductor devices separated by spaces corresponding to where singulation lines will be formed. The method includes providing an alignment structure adjacent to the first surface and providing a material on a second surface of the semiconductor wafer, wherein the material is absent on the second surface directly below the alignment structure. The method includes passing an IR signal through the semiconductor wafer from the second surface to the first surface where the material is absent to detect the alignment structure and align a singulation device to the spaces where the singulation lines on will be formed.
