  • Patent number: 11267099
    Abstract: In some embodiments, the present disclosure, in some embodiments, relates to a method of forming a CMP membrane. The method is performed by providing a malleable material within a cavity within a membrane mold. The cavity has a central region and a peripheral region surrounding the central region. The malleable material within the cavity is cured to form a membrane. Curing the malleable material is performed by heating the malleable material within the central region of the membrane mold to a first temperature and heating the malleable material within the peripheral region of the membrane mold to a second temperature that is greater than the first temperature.
