Abstract: Embodiments disclosed herein generally relate to a slit valve door assembly for sealing an opening in a chamber. A slit valve door that is pressed against the chamber to seal the slit valve opening moves with the chamber as the slit valve opening shrinks so that an o-ring pressed between the slit valve door and the chamber may move with the slit valve door and the chamber. Thus, less rubbing of the o-ring against the chamber may occur. With less rubbing, fewer particles may be generated and the o-ring lifetime may be extended. With a longer lifetime for the o-ring, substrate throughput may be increased.

Abstract: An actuator for use with an on/off solenoid configured to maintain a position corresponding to the energized state of the solenoid when the solenoid is de-energized. The actuator is comprised of a guide that rotates a selector between one of two positions each time the solenoid is energized. One position of the actuator places the selector in an extended position and the other position of the actuator places the selector in a retracted position. To move the selector between the first and second positions, the solenoid is momentarily energized, and in each position of the selector, the solenoid is de-energized. The actuator can be coupled to a poppet valve to maintain the valve in one of two positions when the solenoid is de-energized.
