Abstract
A pin lifter assembly for a substrate support in a substrate processing system includes a lift pin having a shaft, an upper end, and a lower end, and an insert arranged around the lift pin. The insert defines a gap between the insert and the lift pin. A clamp assembly is arranged around the lower end of the lift pin. The lower end of the lift pin is secured within the clamp assembly such that the clamp assembly prevents vertical movement of the lift pin relative to the clamp assembly. The clamp assembly is configured to allow horizontal movement of the lower end of the lift pin within the clamp assembly.
