A vacuum chuck for holding a semiconductor wafer during high pressure processing comprises a wafer platen, first through third lift pins, and an actuator mechanism. The wafer platen comprises a smooth surface, first through third lift pin holes, and a vacuum opening. In use, the vacuum opening applies vacuum to a surface of a semiconductor wafer, which chucks the semiconductor wafer to the wafer platen. The first through third lift pins mount within the first through third lift pin holes, respectively. The actuator mechanism couples the first through third lifting pins to the wafer platen. The actuator mechanism operates to extend the first through third lift pins in unison above the smooth surface of the wafer platen. The actuator mechanism operates to retract the first through third lift pins in unison to at least flush with the smooth surface of the wafer platen.

A high pressure chamber for processing of a semiconductor substrate comprises a high pressure processing cavity, a plurality of injection nozzles, and first and second outlet ports. The high pressure processing cavity holds the semiconductor substrate during high pressure processing. The plurality of injection nozzles are oriented into the high pressure processing cavity at a vortex angle and are operable to produce a vortex over a surface of the semiconductor substrate. The first and second outlet ports are located proximate to a center of the plurality of injection nozzles and are operable in a first time segment to provide an operating outlet out of the first outlet port and operable in a second time segment to provide the operating outlet out of the second outlet port. In an alternative embodiment, an upper surface of the high pressure processing cavity comprises a height variation. The height variation produces more uniform molecular speeds for a process fluid flowing over the semiconductor substrate.

An isolation valve is preferably applied to the semiconductor industry for sealing a process vessel and also operates effectively at plus-atmospheric pressures. A double containment gate valve assembly includes a housing and a movable head assembly within the housing. The housing includes a first access opening and a second access opening. The head assembly is configurable into a first position where an access path through the first and second access openings is clear, and a second position where the access path is blocked.
