Patent number: 8075704Abstract: The present invention discloses a method for the removal of a number of molecular contaminants from surfaces within a device. A purge gas containing oxygen and/or water is introduced into the interior of the device, contacting at least a portion of the interior surfaces. A contaminated purge gas is produced by transferring a portion of the contamination from the interior surfaces into the purge gas. The contaminated purge gas is removed from the device and the process is continued until the contaminant concentration in the contaminated purge gas is below a predetermined level.Type: GrantFiled: June 1, 2004Date of Patent: December 13, 2011Assignee: Entegris, Inc.Inventors: Jeffrey J.

Patent number: 7824628Abstract: A method and apparatus for the decontamination of fluid ammonia are described. Liquid or gaseous ammonia is purified of contaminants by passage through an adsorbent bed, the contaminants accumulating in the bed. A portion of the purified ammonia discharged from the bed is decomposed to hydrogen and nitrogen. The hydrogen is used to regenerate an adsorbent bed which has accumulated sufficient contaminants to reduce its ability to further decontaminate incoming ammonia satisfactorily. Preferably there are a plurality of interconnected adsorbent beds, with some being operated for ammonia decontamination while others are being regenerated, with their operations being reversed as needed to maintain a continual production of decontaminated ammonia from the plurality of beds. Computers or other controllers can be used to control such bed operations and interchanges. Internal production of hydrogen makes the system self-contained and no addition of hydrogen is needed.Type: GrantFiled: May 7, 2002Date of Patent: November 2, 2010Assignee: Entegris, Inc.Inventors: Daniel Alvarez, Jr., Jeffrey J.

Publication number: 20090229346Abstract: A method of detecting a molecular species in an electronics processing environment is disclosed. The method exposes a capture substrate to the processing environment. The capture substrate has a surface area different from the surface area of an electronic substrate undergoing electronics processing. The molecular species is transferred from the environment to the capture substrate. A characteristic of the molecular species is identified, thereby detecting the species. Other methods utilize a capture substrate to remove the molecular species from an electronic processing environment, or use the capture substrate to determine the presence of a molecular species in a transfer container operating between two process environments or two intermediate process steps. Systems for carrying out the methods are also disclosed.Type: ApplicationFiled: July 31, 2006Publication date: September 17, 2009Inventors: Daniel Alvarez, JR., Troy B. Scoggins, Jeffrey J.

Patent number: 7381243Abstract: The invention is a method for the decontamination of CO2 to a sufficient level of purity to allow it to be used in the semiconductor industry. The invention comprises the exposure of fluid CO2 to a combination metallic states of at least one metal under the appropriate conditions for removal of contaminants. The adsorbents are then decontaminated/activated to return the adsorbent to a mixed oxidation state and allow further rounds of decontamination. The adsorbents are selected to be complimentary to each other, preferentially adsorbing different contaminants. Additionally, the adsorbents are selected to undergo reduction differently such that upon regeneration only a portion of the metals are reduced and the adsorbent is returned essentially to its original state.Type: GrantFiled: October 16, 2003Date of Patent: June 3, 2008Assignee: Entegris, Inc.Inventors: Daniel Alvarez, Jr., Jeffrey J.

Patent number: 7376489Abstract: An interactive method and apparatus are disclosed through which a fluid purification system operator inputs the system's parameters and the method then identifies one or more fluid purification equipment packages which will be optimized at the component level to the operator's specific requirements. The invention includes a relational database containing data on fluid purification equipment, the components thereof and ancillary equipment, and associated operational software to which the operator gains access through a computer and which then presents to the operator a series of questions relevant to gas purification equipment and system requirements. The questions are such that the responses elicited from the operator for each question determine what the successive questions will be and what optimal components will be identified. The software and databases may be in memory on the computer, embodied on CDs or DVDs run by the computer, or accessed through the Internet.Type: GrantFiled: September 14, 2000Date of Patent: May 20, 2008Assignee: Entegris, Inc.Inventor: Jeffrey J.

Patent number: 7101416Abstract: A method and composition for the removal of contaminants in a gas stream used in the contamination sensitive processes of photolithography and metrology are described. The synergistic effect of a combination of an electropositive metal component, a high silica zeolite, and a late transition metal compound effects removal or reduction of the contaminates in the gas which interfere with light transmittance to the ppb or ppt levels necessary for the gas to be suitable for these uses. The removal of neutral polar molecules, neutral polar aprotic molecules, protic and aprotic alkaline molecules, acidic polar species, and neutral non-polar aprotic molecules is accomplished with the claimed composition. Depending on the type of contaminant, the composition components are each varied from 10 to 80 parts by volume, with the total composition limited to 100 parts by volume.Type: GrantFiled: October 23, 2003Date of Patent: September 5, 2006Assignee: Mykrolis CorporationInventors: Daniel Alvarez, Jr., Jeffrey J.
