  • Patent number: 11742235
    Abstract: Embodiments described herein generally relate to process chambers with coaxial lift devices. In some embodiments, the device comprises both a bottom bowl lift and a pedestal lift. The bottom bowl lift supports a bottom bowl and is configured to move the bottom bowl into a position that reduces the process volume. The bottom bowl lift is co-axial with the pedestal lift and the bottom bowl lift and the pedestal lift are attached for vacuum operation. The pedestal lift includes multiple actuators to create a dynamic lift mechanism. Both systems complete a nested system such that the bottom bowl lift is adjustable and can close the bottom bowl creating a symmetric and small process volume. The pedestal lift can move independently to its process position and tilt in a desired direction without interference with the bottom bowl lift, increasing film uniformity on a processed substrate.
