摘要： A port in a window member provides first access to a process chamber interior for gas injection and second optical access for process analysis and measurement. Plasma-induced etching and deposition in a bore of a gas injector integral with the window member is reduced by a grounded shield surrounding an access region, and coatings reduce particle flaking from walls of a first clear optical aperture of the injector and from a second clear optical aperture of a gas and optical access fitting,. The shield surrounds the region, and is configured with couplers to hold the gas and optical access fitting to the window member for access to the injector. The couplers compress seals so that a gas bore in the fitting is sealed to a plenum of the injector, while allowing optical access into the chamber through the first clear optical aperture and the second clear optical aperture.

摘要： This invention is an apparatus for purging unwanted gasses from the Front Opening Unified Pod (FOUP). It consists of a purging wand which is inserted into the chamber for an optimal purge. The purging wand moves back and forth along a simple axis activated by a linkage robot. The wand is carried along a track with the FOUP and when its reaches its optimal position inside the FOUP, the source of cleaning gas is allowed to flow into and spray out of the wand thereby purging the FOUP. After the purging is completed, the linkage robot withdraws the wand from within the FOUP to its original position.

摘要： A vacuum chamber with a cover with a first section, a second section, and a pocket between the first section and second section is provided. The vacuum chamber has a main cavity to which the first section is adjacent. The vacuum chamber may be used for plasma processing, which may require a critical element to be supported by the first section. The pocket is in fluid communication with the main cavity. When a vacuum is created in the main cavity, the pressure is also reduced in the pocket. As a result, the second section of the cover is deformed by the vacuum in the pocket. However, the vacuum in the pocket helps to prevent the first section from deforming, providing better support for the critical element.

摘要： A symmetrical semiconductor reactor for semiconductor processing, comprising a liner, a process chamber, a valve chamber, a slot valve plate, a liner aperture plate, a rod, and an actuator. The liner has a liner aperture adapted to provide passage for a wafer and to receive the liner aperture plate. The process chamber is coupled to the liner and the valve chamber. The actuator is coupled to the slot valve plate and moves the slot valve plate from the “closed” to the “open” position and vice versa. Since the slot valve plate is coupled to the liner aperture plate by the rod, the actuator is capable of moving the slot valve plate and the liner aperture plate at the same time. However, the precise movements of the liner aperture plate are dependent on the particular rod embodiment.

摘要： A plasma processing chamber is provided which provides improved wafer area pressure control. The plasma processing chamber is a vacuum chamber with a device connected for generating and sustaining a plasma. Part of this device would be an etchant gas source and an exhaust port. A confinement ring defines an area above a wafer. The wafer area pressure is dependent on the pressure drop across the confinement ring. The confinement ring is part of a confinement device that provides wafer area pressure control greater than 40%. Such a confinement device may be a fixed vertical restriction ring in addition to the confinement ring, where the confinement ring is adjustable. In the alternative, three adjustable confinement rings may be used to provide the desired wafer area pressure control.
