Energy is applied to the second set of precursors in the second energy application zone effective to react and form solid material about the solid particles from the second set of precursors with the solid particles with solid material thereabout having maximum diameter of no greater than 100 nanometers. Other aspects are contemplated.Type: GrantFiled: March 11, 2003Date of Patent: October 12, 2004Assignee: Micron Technology, Inc.Inventor: Trung Tri Doan

Patent number: 6797333Abstract: A treatment for silicone liner coatings after undergoing UV curing. The silicone coats a liner to facilitate its removal from the adhesive attached to a label. The silicone, while a liquid, forms a layer on the liner. UV radiation cures the liquid silicone and causes it to become a coherent, virtually solid layer. Heating the cured silicone layer and allowing it to rest for a short period of time then permits the immediate contact with it of the label's adhesive side without incurring inseparability of the silicone-coated liner from the adhesive-coated label.Type: GrantFiled: May 31, 2002Date of Patent: September 28, 2004Assignee: Print-O-Tape, Inc.Inventors: Roger L. Haase, Carl J. Walliser

Patent number: 6770352Abstract: Disclosed is a film provided with a hardcoat which has high surface hardness and improved apparent scratch resistance. This film provided with a hardcoat comprises: a transparent substrate film; and, stacked on the transparent substrate film in the following order, a hardcoat and a slip layer. The hardcoat is formed of a cured product of a material comprising an ultraviolet-curable resin and a photopolymerization initiator which initiates the photopolymerization of the ultraviolet-curable resin upon exposure to ultraviolet light in its wavelength region other than the wavelength region absorbable by the transparent substrate film. The slip layer contains a slip agent.Type: GrantFiled: November 19, 2001Date of Patent: August 3, 2004Assignee: Dai Nippon Printing Co., Ltd.Inventors: Hiroko Suzuki, Fumihiro Arakawa

Patent number: 6756085Abstract: Low dielectric constant materials with improved elastic modulus and material hardness. The process of making such materials involves providing a dielectric material and ultraviolet (UV) curing the material to produce a UV cured dielectric material. UV curing yields a material with improved modulus and material hardness. The improvement is each typically greater than or about 50%. The UV cured dielectric material can optionally be post-UV treated. The post-UV treatment reduces the dielectric constant of the material while maintaining an improved elastic modulus and material hardness as compared to the UV cured dielectric material. UV cured dielectrics can additionally exhibit a lower total thermal budget for curing than for furnace curing processes.Type: GrantFiled: July 21, 2003Date of Patent: June 29, 2004Assignee: Axcelis Technologies, Inc.Inventors: Carlo Waldfried, Qingyuan Han, Orlando Escorcia, Ivan L.

Patent number: 6749898Abstract: There are disclosed a casting film which is used for producing a ceramic green sheet and which comprises a substrate film and a cured layer formed thereon of an addition reaction type silicone composition containing a photosensitizer, in which the cured layer is formed by heat-treating a layer of a photosensitizer-containing addition reaction type silicone composition in a coating amount expressed in terms of solid content in the range of 0.01 to 0.2 g/m2 at a temperature in the range of 40 to 120° C., followed by a treatment with ultraviolet ray irradiation. The casting film is excellent in coatability of ceramic slurry and releasability of ceramic green sheet, and is imparted with high flatness which has heretofore never been realizable by any of conventional casting films.Type: GrantFiled: September 7, 2001Date of Patent: June 15, 2004Assignee: Lintec CorporationInventors: Toru Nakamura, Tomishi Shibano
