Abstract

Aspects of the present disclosure generally relate to apparatus and methods for an adjustable de-chucking voltage associated with an electrostatically charged substrate in a processing chamber. An example method of de-chucking a substrate disposed in a process chamber includes processing a substrate in a chamber body, the substrate being coupled to a substrate support comprising a chucking electrode. The method further includes monitoring a property associated with a lift pin assembly movable relative to the chucking electrode via an actuator. The method further includes adjusting a first voltage level applied to the chucking electrode in response to the property associated with the lift pin assembly satisfying one or more criteria.
