Patent number: 8657959Abstract: An apparatus for atomic layer deposition of a material on a moving substrate comprises a conveying arrangement for moving a substrate along a predetermined planar or curved path of travel and a coating bar having at least one precursor delivery channel. The precursor delivery channel conducts a fluid containing a material to be deposited on a substrate toward the path of travel. When in use, a substrate movable along the path of travel defines a gap between the outlet end of the precursor delivery channel and the substrate. The gap defines an impedance Zg to a flow of fluid from the precursor delivery channel. A flow restrictor is disposed within the precursor delivery channel that presents a predetermined impedance Zfc to the flow therethrough. The restrictor is sized such that the impedance Zfc is at least five (5) times, and more preferably at least fifteen (15) times, the impedance Zg. The impedance Zfc has a friction factor f.Type: GrantFiled: December 16, 2010Date of Patent: February 25, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Geoffrey Nunes, Richard Dale Kinard

Patent number: 8529700Abstract: A vapor deposition apparatus includes an insert within which a material is deposited on the surface of a film. A cassette includes end plates each having a rib that edgewise receive a spiral wrapping of a film at least 300 mm wide. Spaces between turns of the wrapping define a gas flow channel and spaces between adjacent turns of one rib define inlet openings that communicate with the channel. Each rib has a predetermined width dimension, a predetermined average thickness dimension, and a width-to-thickness aspect ratio of at least 2:1. The spacing between end plates is at least 300 mm and is also greater than the film width at deposition temperature. The width dimension of each rib is between about 0.5% to about 2.0% of the end plate spacing. A diverging flow director contacts one end plate to directing gaseous fluid toward the inlet openings in that end plate.Type: GrantFiled: August 31, 2009Date of Patent: September 10, 2013Assignee: E I Du Pont de Nemours and CompanyInventors: Peter Francis Carcia, Richard Dale Kinard, Robert Scott McLean, Geoffrey Nunes, Kirstin H.

Patent number: 8388742Abstract: The present invention relates to an apparatus to measure permeation of a gas through a membrane. The membrane is mounted on a flange with two sealing areas. The region between the sealing areas defines an annular space. The annular space is swept with a gas in order to carry away any of the permeating gas which may leak through the sealing areas.Type: GrantFiled: January 11, 2011Date of Patent: March 5, 2013Assignee: E I du Pont de Nemours and CompanyInventor: Geoffrey Nunes

Patent number: 8308886Abstract: The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.Type: GrantFiled: July 17, 2006Date of Patent: November 13, 2012Assignee: E I du Pont de Nemours and CompanyInventors: Gerald Donald Andrews, Marc B Goldfinger, Mark Andrew Harmer, Gary Delmar Jaycox, Lynda Kaye Johnson, Irina Malajovich, William J Marshall, Elizabeth Forrester McCord, Charles Nehemiah McEwen, Jeffrey Scott Meth, Richard Kevin Bailey, Geoffrey Nunes, Rinaldo Soria Schiffino, Paul J Shannon, Kenneth George Sharp, Karyn B Visscher, Graciela Beatriz Blanchet, John W Catron, Jr., Reid John Chesterfield, Thomas C Felder, Feng Gao, Howard David Glicksman
