Patent number: 8764998Abstract: A method for manufacturing a composite substrate that prevents undesirable effects of etching a thin film includes a pattern forming step, an ion implanting step, a bonding step, and a separation step. In the pattern forming step, a pattern region and a reverse pattern region are formed on a principal surface of a functional material substrate. In the ion implanting step, by implanting ions into the functional material substrate, a separation layer is formed inside at a certain distance from the surface of each of the pattern region and the reverse pattern region. In the bonding step, the functional material substrate at the pattern region is bonded to a supporting substrate. In the separation step, the pattern region is separated from the functional material substrate, and the reverse pattern region is made to fall off.Type: GrantFiled: July 28, 2011Date of Patent: July 1, 2014Assignee: Murata Manufacturing Co., Ltd.Inventors: Kiyoto Araki, Takashi Iwamoto, Hajime Kando

Publication number: 20140175049Abstract: Roll-to-roll processes for manufacturing touch sensors using a sheet of patterned photoresist film are disclosed. The photoresist film can include a sheet of photoresist material, such as DFR, that has been patterned by removing portions of the photoresist film using a die or laser cutting technique. In some examples, the photoresist film can be patterned such that the patterned photoresist film can be laminated to a base film and used as an etching mask or a photoresist layer in a roll-to-roll manufacturing process. In this way, the patterned photoresist film can be used in place of conventional photoresist films in roll-to-roll processes, thereby obviating the need for subsequent exposure and development operations that would otherwise be performed when using conventional photoresist films. As a result, the chance that a defect is introduced into the touch sensors is reduced by reducing the number of operations performed in the roll-to-roll process.Type: ApplicationFiled: December 21, 2012Publication date: June 26, 2014Applicant: Apple Inc.Inventors: Siddharth MOHAPATRA, Sunggu KANG, John Z.
