    Abstract: A plasma process method and apparatus for use with a vacuum instrument having a vacuum chamber evacuated by an oil free high vacuum pump to a base pressure below about 1 Pa. A gas buffer chamber in fluid communication with the plasma chamber, the gas buffer chamber having a volume about 1/500 to 1/2000 of the volume of the vacuum chamber. A valve between the plasma chamber and the gas chamber permits flow between the gas chamber and the plasma chamber, wherein, upon opening the valve, gas is admitted into the plasma chamber and pressure in the plasma chamber rises temporarily to between about 10 and about 200 Pa and plasma ignition can be obtained when the plasma excitation device is energized simultaneously. A flow restriction between the gas source and the gas chamber has a maximum flow rate therethrough of about 25 sccm. (standard cubic centimeters per minute) or less so that pressure in the plasma chamber remains between about 1 and about 7 Pa after plasma ignition to maintain plasma conduction and to avoid overloading or heating of the high vacuum pump.

    Abstract: Provided are an apparatus and method for treating wafers using a supercritical fluid. The wafer treatment apparatus includes a plurality of chambers; a first supply supplying a first fluid in a supercritical state; a second supply supplying a mixture of the first fluid and a second fluid; a plurality of first and second valves; and a controller selecting a first chamber of the plurality of chambers for wafer treatment to control the open/closed state of each of the plurality of first valves so that the first fluid can be supplied only to the first chamber of the plurality of chambers and selecting a second chamber of the plurality of chambers to control the open/closed state of each of the plurality of second valves so that the mixture of the first fluid and a second fluid can be supplied only to the second chamber of the plurality of chambers. The wafer treatment method involves performing a predetermined treatment such as etching, cleaning or drying on wafers within only one of the plurality of chambers, followed by wafer treatment on the succeeding chamber, and thus allowing for sequential wafer treatment within each of the plurality of chambers.

    Abstract: A method and apparatus for cleaning a wafer. The wafer is heated and moved to a processing station within the apparatus that has a platen either permanently in a platen down position or is transferable from a platen up position to the platen down position. The wafer is positioned over the platen so as not to contact the platen and provide a gap between the platen and wafer. The gap may be generated by positioning the platen in a platen down position. A plasma flows into the gap to enable the simultaneous removal of material from the wafer front side, backside and edges. The apparatus may include a single processing station having the gap residing therein, or the apparatus may include a plurality of processing stations, each capable of forming the gap therein for simultaneously removing additional material from the wafer front side, backside and edges.
