Publication number: 20150255348Abstract: The present invention has an object to perform a peeling treatment in a short time. Peeling is performed while a peeling layer is exposed to an atmosphere of an etching gas. Alternatively, peeling is performed while an etching gas for a peeling layer is blown to the peeling layer in an atmosphere of an etching gas. Specifically, an etching gas is blown to a part to be peeled while a layer to be peeled is torn off from a substrate. Alternatively, peeling is performed in an etchant for a peeling layer while supplying an etchant to the peeling layer.Type: ApplicationFiled: May 20, 2015Publication date: September 10, 2015Inventors: Eiji Sugiyama, Yoshitaka Dozen, Yumiko Fukumoto, Hideaki Kuwabara, Shunpei Yamazaki

Publication number: 20150185552Abstract: To provide a method of manufacturing an optical film formed on a plastic substrate. There is provided a method of manufacturing an optical film including the steps of laminating a separation layer and an optical filter on a first substrate, separating the optical filter from the first substrate, attaching the optical filter to a second substrate. Since the optical film manufactured according to the invention has flexibility, it can be provided on a portion or a display device having a curved surface. Further, the optical film is not processed at high temperatures, and hence, an optical film having high yield with high reliability can be formed. Furthermore, an optical film having an excellent impact resistance property can be formed.Type: ApplicationFiled: March 12, 2015Publication date: July 2, 2015Inventors: Akio Yamashita, Yumiko Fukumoto, Yuugo Goto

Patent number: 8673739Abstract: It is an object of the invention to provide a lightweight semiconductor device having a highly reliable sealing structure which can prevent ingress of impurities such as moisture that deteriorate element characteristics, and a method of manufacturing thereof. A protective film having superior gas barrier properties (which is a protective film that is likely to damage an element if the protective film is formed on the element directly) is previously formed on a heat-resistant substrate other than a substrate with the element formed thereon. The protective film is peeled off from the heat-resistant substrate, and transferred over the substrate with the element formed thereon so as to seal the element.Type: GrantFiled: November 23, 2011Date of Patent: March 18, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Toru Takayama, Yuugo Goto, Yumiko Fukumoto, Junya Maruyama, Takuya Tsurume

Patent number: 8461013Abstract: An IC card is more expensive than a magnetic card, and an electronic tag is also more expensive as a substitute for bar codes. Therefore, the present invention provides an extremely thin integrated circuit that can be mass-produced at low cost unlike a chip of a conventional silicon wafer, and a manufacturing method thereof. One feature of the present invention is that a thin integrated circuit is formed by a formation method that can form a pattern selectively, on a glass substrate, a quartz substrate, a stainless substrate, a substrate made of synthetic resin having flexibility, such as acryl, or the like except for a bulk substrate. Further, another feature of the present invention is that an ID chip in which a thin film integrated circuit and an antenna according to the present invention are mounted is formed.Type: GrantFiled: May 10, 2010Date of Patent: June 11, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shinji Maekawa, Gen Fujii, Junya Maruyama, Toru Takayama, Yumiko Fukumoto, Yasuyuki Arai

Patent number: 7883989Abstract: It is an object of the invention to provide a peeling method which does not damage a peeling layer, and to perform peeling not only a peeling layer having a small-size area but also an entire peeling layer having a large-size area with a preferable yield. In the invention, after pasting a fixing substrate, a part of a glass substrate is removed by scribing or performing laser irradiation on the glass substrate which leads to providing a trigger. Then, peeling is performed with a preferable yield by performing peeling from the removed part. In addition, a crack is prevented by covering the entire face except for a connection portion of a terminal electrode (including a periphery region of the terminal electrode) with a resin.Type: GrantFiled: October 14, 2009Date of Patent: February 8, 2011Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Yuugo Goto, Yumiko Fukumoto, Toru Takayama, Junya Maruyama, Takuya Tsurume
