A transparent conductive film layer (11) and a metal layer (12) are laminated on a transparent substrate (1), and the transparent conductive film layer (11) and the metal layer (12) are formed into predetermined electrode patterns, with use of one resist pattern. A protective film (13) covering the transparent conductive film layer (11) and the metal layer (12) is formed, and openings (14, 15, and 16) are provided at predetermined positioned in the protective film (13). By etching with use of the protective film (13) having the openings (14, 15, and 16), the metal layer (12) is removed so that the transparent conductive film layer (11) is exposed, whereby at least either touch electrodes (2) or connection terminals (5) are formed.Type: GrantFiled: November 18, 2010Date of Patent: April 29, 2014Assignee: Sharp Kabushiki KaishaInventor: Katsunori Misaki

Patent number: 8673163Abstract: Fabrication of thin sheets of glass or other substrate material for use in devices such as touch sensor panels is disclosed. A pair of thick glass sheets, typically with thicknesses of 0.5 mm or greater each, may each be patterned with thin film on a surface, sealed together to form a sandwich with the patterned surfaces facing each other and spaced apart by removable spacers, either or both thinned on their outside surfaces to thicknesses of less than 0.5 mm each, and separated into two thin glass sheets. A single thick glass sheet, typically with a thickness of 0.5 mm or greater, may be patterned, covered with a protective layer over the pattern, thinned on its outside surface to a thickness of less than 0.5 mm, and the protective layer removed. This thinness of less than 0.5 mm may be accomplished using standard LCD equipment, despite the equipment having a sheet minimum thickness requirement of 0.5 mm.Type: GrantFiled: June 27, 2008Date of Patent: March 18, 2014Assignee: Apple Inc.Inventors: John Z.

Patent number: 8562848Abstract: Disclosed is an end point detecting method of metal etching and a device thereof. The end point detecting method of metal etching comprises: performing scan to a metal film to acquire a proportion of a transparency area of the metal film in a scanned area; judging whether the proportion of the transparency area reaches a predetermined value or not; and confirming a current etching time of the metal film as an etching end point time when the predetermined value is reached. The device comprises an acquirement module, a judgment module and a confirmation module. The acquirement module performs scan to the metal film to acquire the proportion of the transparency area. The judgment module judges whether the proportion reaches the predetermined value or not. The confirmation module confirms the current etching time of the metal film as the etching end point time when the proportion reaches the predetermined value.Type: GrantFiled: August 28, 2011Date of Patent: October 22, 2013Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventors: Chin-wen Wang, Chengming He
