  • Publication number: 20240079273
    Abstract: An embodiment disclosed herein includes a method of dicing a wafer comprising a plurality of integrated circuits. In an embodiment, the method comprises forming a mask above the semiconductor wafer, and patterning the mask and the semiconductor wafer with a first laser process. The method may further comprise patterning the mask and the semiconductor wafer with a second laser process, where the second laser process is different than the first laser process. In an embodiment, the method may further comprise etching the semiconductor wafer with a plasma etching process to singulate the integrated circuits.
    Type: Application

  • Publication number: 20210233816
    Abstract: Methods of dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. In an example, a method of dicing a semiconductor wafer having a plurality of integrated circuits involves forming a mask above the semiconductor wafer, the mask composed of a layer covering and protecting the integrated circuits. The mask is then patterned with a spatially multi-focused laser beam laser scribing process to provide a patterned mask with gaps, exposing regions of the semiconductor wafer between the integrated circuits. The semiconductor wafer is then plasma etched through the gaps in the patterned mask to singulate the integrated circuits.
