Patent number: 7883840Abstract: In a developing method, a developer is supplied onto a resist film provided on a substrate, made of a resist and having an upper surface on which design patterns having different mask opening ratios are exposed and a development reaction is caused to proceed on the resist film with the supplied developer. After the development, the substrate is rotated so that the developer and the resist dissolved in the developer are removed. Then, a rinsing solution is supplied onto the resist film subjected to development and the substrate is rotated, thereby washing out the developer and the resist dissolved in the developer. The rotation speed of the substrate in removing the developer is a half or less of the rotation speed of the substrate in the rinsing step of washing out the resist.Type: GrantFiled: December 28, 2006Date of Patent: February 8, 2011Assignee: Panasonic CorporationInventors: Hidekazu Kitahara, Kenji Noda, Kenichi Asahi, Naohiko Ujimaru, Hirofumi Fukumoto

Patent number: 7875420Abstract: To improve the surface roughness of a resist film formed on a wafer. In a coating and developing treatment system, a wafer W on which a resist film has been formed and subjected to exposure and developing treatment is adjusted to a predetermined temperature. A solvent gas is supplied to the surface of the temperature-adjusted wafer W to dissolve the surface of the resist film. The wafer W is then heated to volatilize the solvent in the resist film to thereby heat shrink the resist film. This levels the projections and depressions on the surface of the resist film so as to improve the surface roughness of the resist film.Type: GrantFiled: May 31, 2004Date of Patent: January 25, 2011Assignee: Tokyo Electron LimitedInventor: Yuichiro Inatomi

Patent number: 7875416Abstract: A liquid-type composition for forming a photosensitive polymer complex and a method of preparing a photosensitive polymer complex containing silver nanoparticles using the same are provided. The composition for forming a photosensitive polymer complex includes a multifunctional epoxy resin, a photoacid generator, an organic solvent and a silver compound, or additionally includes a multifunctional acrylate resin and a photoinitiator, or an additive, e.g., a surfactant or a flow improver. This composition is applied, selectively exposed, and developed, thus preparing a photosensitive polymer complex, which contains silver nanoparticles uniformly dispersed and formed in the polymer pattern portion thereof through photo reduction and is therefore improved in terms of physical or chemical properties, e.g., heat resistance and wear resistance.Type: GrantFiled: June 5, 2007Date of Patent: January 25, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Jong Jin Park, Byung Ha Park, Young Ung Ha

Patent number: 7867686Abstract: A method for electroless plating of metal on a laser-patterned substrate. A substrate is provided on which both a thermal imaging layer and catalytic layer are deposited. On exposure to a laser beam, sufficient levels of radiation are converted to heat in the thermal imaging layer to render the exposed regions of the adjacent catalytic layer inactive. The laser-patterned substrate is then exposed to a reaction solution which initiates the growth of a metal film on the unexposed regions of the catalytic layer.Type: GrantFiled: February 10, 2005Date of Patent: January 11, 2011Assignees: Plastic Logic Limited, Conductive Inkjet Technology LimitedInventors: Michael J. Banach, John Mills, James Watts, Alan Lionel Hudd, James Edward Fox, Philip Gareth Bentley
