  • Patent number: 9786486
    Abstract: A system and method concurrently processes multiple wafers. A cassette structure includes multiple chucks and a drive spool for supporting and rotating the chucks. Each chuck holds a wafer in position while rotating. The cassette structure is loaded into a process chamber. Each chuck includes a self-locking mechanism that is activated by the centrifugal force generated from the rotation of the chuck. The self-locking mechanism centers and holds a wafer in position with respect to the chuck. A drive motor drives the drive spool, which causes the chucks to rotate. As the chucks are being rotated, a dispensing assembly delivers a processing chemical to the wafers.
