摘要： The invention teaches a purification system which uses a series of operations, in a single unit, to purify air, while extending the life of the purification units. Air is passed through a coarse water trap to remove liquid. The semi-dry air, which is usually less than 3000 ppm of water vapor, is then passed through adsorbers, which remove the remaining moisture and all the carbon dioxide in a purification process. The drying of the air before passing it through the adsorbers allows for greatly improved efficiency of air purification and extends the life of both the oxygen catalyst and the adsorption columns. The present invention also flows the air to be purified through adsorption columns twice, before and after passing the air through an oxygen catalyst unit. The oxidizing catalyst, which is heated to a temperature of approximately 300 degrees centigrade, converts carbon monoxide and hydrocarbons to H2O and CO2. The newly converted H2O and CO2 are then removed by the second pass through a second adsorption column in the second flow direction or downstream. The flows of air are then rotated with a third column, which is thermally regenerating with the facilitation of a regeneration air supply from the purified air.

摘要： An improved getter pump module includes a number of getter elements and a heating element that heats the getter elements. The getter elements are preferably porous, sintered getter disks. The heating element is disposed proximate to the getter elements and provides heat to activate the getter material and cause it to pump desired gasses. The getter elements and heater element are partially surrounded by a focus shield that is positioned between the getter elements and a wall of a processing chamber that encloses the getter elements, the heater element, and the focus shield. The focus shield is provided to reflect thermal energy to the getter material from the heater element, to provide high pumping speeds or short activation/baking times, and to reduce the heat seen by the chamber from the heating element. In certain embodiments of the present invention the focus shield is angled as to be wedge shaped, and may include planar extension portions. Multiple focus shields are provided in some embodiments.

摘要： A cryogenic valve that uses conventional materials in unusual ways to achieve very low heat leak, excellent strength, pressure or vacuum integrity and modest manufacturing cost. Heat leak rates on the order of 0.5 watt have been obtained in a 1.5 inch valve. Such performance is made possible by the unique structure of the valve stem, of the bonnet extension, and of certain insulative spacers. The valve stem consists of a thin wall tube of wound glass filaments in an epoxy matrix. The bonnet extension consists of a thin wall stainless steel bellows wound with glass fibers in an epoxy matrix. The insulative spacers have a shape that results in a long tortuous conduction path when they are stacked inside the valve stem and in the space between the valve stem and the bonnet extension.

摘要： The present invention provides a gas purification system with improved efficiency, simpler construction, cost reductions, form factor improvements, and increased durability. The present invention provides cost and form factor improvements through fewer components overall and through utilizing multiple integrated components. Prior art gas purification systems are more bulky and complicated. The present invention achieves increased thermal efficiency through utilization of a regenerative heat exchanger to recapture a portion of the heat energy transferred to the gas during the purification process. Prior art purifiers lacked a regenerative heat exchanger. The present invention integrates the two components into one integrated heater and purification vessel assembly. The present invention integrates the two discrete components into one integrated hydrogen sorption and particle filter assembly. The integrated hydrogen sorption and particle filter assembly is also capable of operating at higher temperatures. This eases maintenance and manufacture. The resulting gas purification system is simpler through utilizing fewer components, smaller by utilizing fewer and integrated components, and reduced cost through fewer components, smaller components and through reduced manufacture labor requirements.

摘要： A semiconductor manufacturing system includes a getter-based gas purifier coupled in flow communication with a gas distribution network for a semiconductor fabrication facility. The gas distribution network supplies purified gas to at least one wafer processing chamber in the semiconductor fabrication facility. The gas purifier includes a getter column having a metallic vessel with an inlet, an outlet, and a containment wall extending between the inlet and the outlet. Getter material which purifies gas flowing therethrough by sorbing impurities therefrom is disposed in the vessel. A first temperature sensor is disposed in a top portion of the getter material. The first temperature sensor is located in a melt zone to detect rapidly the onset of an exothermic reaction which indicates the presence of excess impurities in the incoming gas to be purified. A second temperature sensor is disposed in a bottom portion of the getter material. The second temperature sensor is located in a melt zone to detect rapidly the onset of an exothermic reaction which indicates that excess impurities are being backfed into the getter column. First and second high melting point, nonmetallic liners are disposed in the vessel such that at least some of the top and bottom portions, respectively, of the getter material is separated from the containment wall of the vessel. A getter-based gas purifier, a method of making an integrated circuit device, and a method of protecting a getter column are also described.
