  • Patent number: 10315286
    Abstract: A system includes a CMP carrier that includes a resilient flexible membrane upon which a wafer is mounted, at least three ports for supplying air to the resilient flexible membrane to pneumatically pushing on the wafer through pressure applied throughout the surface area of the resilient flexible membrane to have more uniform pressure. Each port provides pressure to different components of the carrier to adjust pressure or vary pressure during processing of the wafer. Further, the system includes a processor and software program for implementing the CMP carrier with existing CMP machines. The software application converts the air pressure applied to the carrier into units that allow the CMP machine to receive expected data and operate in accordance with the existing commands.
