Abstract
A substrate support includes a conductive baseplate arranged to support a ceramic layer. The conductive baseplate includes a first cavity extending along an axis perpendicular to a horizontal plane defined by the conductive baseplate. A coupling assembly is arranged within the first cavity. The coupling assembly includes a gear configured to rotate about the axis. A pin arranged within the first cavity extends along the axis through the gear and into a second cavity below the conductive baseplate. Rotation of the gear causes the pin to move upward or downward relative to the conductive baseplate. The pin is retained within the second cavity when the gear is rotated to cause the pin to move downward into the second cavity.
