Abstract:
Techniques for a door system for sealing an opening between two chambers in a semiconductor processing system are described. A sealing member seals the opening when a door is in a closed position. To selectively open and close the opening, an actuator moves the door. A valve actuator switch provides a first or second pressure to the actuator depending on the pressure inside a first chamber. In one embodiment, a sensor monitors the pressure inside the first chamber.
