  • Patent number: 11545394
    Abstract: A semiconductor wafer dicing process is disclosed for dicing a wafer into individual dies. Scribe lines are formed within a polymer coating to expose regions of wafer to form a pre-processed product. The pre-processed product within the chamber is plasma etched to remove the exposed regions of the wafer to separate the individual dies and form a processed product. A frame cover is then removed and the processed product, wafer frame and adhesive tape are exposed to an oxygen plasma within the chamber to partially remove an outermost region of the polymer coating, which is most heavily contaminated with fluorine, to leave a residual polymer coating on the individual dies and form a post-processed product. The residual polymer coating on the individual dies of the post-processed product is then removed.
