    摘要: Methods and apparatuses for processing microfeature workpieces are disclosed herein. In one embodiment, a workpiece support carries a workpiece in a processing volume of a processing chamber. A first fluid delivery device directs an unsupported stream of a first fluid into the processing volume. A second fluid delivery device directs an unsupported stream of a second fluid into the processing volume. A first fluid collector receives at least a portion of the first fluid, and a second fluid collector receives at least a portion of the second fluid. Accordingly, embodiments of the apparatus support the use of multiple fluids in a single processing volume to control, restrict, and/or eliminate mixing between the two fluids while reducing and/or eliminating the need for purging and/or rinsing portions of the apparatus. The rotation rate and/or position of the workpiece can also be controlled to control the manner in which the fluids are collected.

    摘要: A pilot valve is operated by a solenoid formed by a coil wound around a non-magnetic spool that has a bore. A rare earth permanent magnet is inside the bore adjacent one end and abuts a flux concentrator farther inside the bore. A plunger is slidably located within the bore biased away from the flux concentrator by a spring and projects out another end of the bore. An enclosure of magnetic material completes a magnetic flux path around the solenoid and has an aperture though which the plunger projects. The pilot valve includes a cage of rigid non-magnetic material which abuts the enclosure and has a recess which supports the plunger out of contact with the housing. The plunger selectively opens and closes a pilot tube through the cage to operate a diaphragm the responds by engaging a primary valve seat to control the flow of fluid through a valve body.
