  • Publication number: 20230118617
    Abstract: Provided herein are polishing pads in which microcapsules that include a polymer material and are dispersed, as well as methods of making and using the same. Such microcapsules are configured to break open (e.g., when the polishing pad is damaged during the dressing process), which releases the polymer material. When contacted with ultraviolet light the polymer material at least partially cures, healing the damage to the polishing pad. Such polishing pads have a longer lifetime and a more stable remove rate when compared to standard polishing pads.
