Patent number: 7407889Abstract: The present invention improves a method of forming a surface unevenness using a difference in etching rates, and relaxes limitations on substrates in this method. In a method of the present invention, an uneven surface is formed by a method including applying pressure to a predetermined region in a surface of a thin film formed on a substrate, and etching a region including at least a portion of the predetermined region and at least a portion of the reminder of the surface that excludes the predetermined region. An etching rate difference within the thin film increases freedom in selecting a substrate material.Type: GrantFiled: November 19, 2004Date of Patent: August 5, 2008Assignees: Nippon Sheet Glass Company, Limited, Olympus CorporationInventors: Keiji Tsunetomo, Shinya Okamoto, Yasuhiro Saito, Junji Kurachi, Akihiro Koyama, Hirotaka Koyo, Takeshi Hidaka, Hiroaki Kasai, Masamichi Hijino, Yasushi Nakamura

Publication number: 20070138130Abstract: The present invention provides a glass substrate having a minute texture being provided on the surface and having good acid durability with high protrusion forming efficiency. According to the present invention, unevenness is formed on the surface by pressing a predetermined area of the surface of the glass substrate containing at least one oxide selected from the group consisting of SiO2, B2O3, P2O5, GeO2, As2O5, ZrO2, TiO2, SnO2, A2O3, MgO, and BeO and having a composition wherein the content of this at least one oxide is above 90 mol %, and subsequently by etching an area including this predetermined area. In the composition of this glass substrate, the ratio of oxides of network formers or intermediates is high, so that the glass substrate becomes easy to be compressed. This enables to obtain high protrusion forming efficiency even when selective leaching of a component easily leached into etchant is not employed, thereby satisfying acid durability as well.Type: ApplicationFiled: February 4, 2005Publication date: June 21, 2007Applicants: NIPPON SHEET GLASS COMPANY, LIMITED, OLYMPUS CORPORATIONInventors: Junji Kurachi, Akihiro Koyama, Shinya Okamoto, Yasuhiro Saito, Keiji Tsunetomo, Hirotaka Koyo, Takeshi Hidaka, Hiroaki Kasai, Yasushi Nakamura
