Patent number: 8030745Abstract: The present invention provides an ID chip or an IC card in which the mechanical strength of an integrated circuit can be enhanced without suppressing a circuit scale. An ID chip or an IC card of the present invention has an integrated circuit in which a TFT (a thin film transistor) is formed from an insulated thin semiconductor film. Further, an ID chip or an IC card of the present invention has a light-emitting element and a light-receiving element each using a non-single-crystal thin film for a layer conducting photoelectric conversion. Such a light-emitting element or a light-receiving element may be formed consecutively to (integrally with) an integrated circuit or may be formed separately and attached to an integrated circuit.Type: GrantFiled: February 28, 2005Date of Patent: October 4, 2011Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Shunpei Yamazaki

Patent number: 8026524Abstract: Semiconductor devices in which one or more LEDs are formed include a dielectric region formed on a n/p region of the semiconductor, and that a metallic electrode can be formed on (at least partially on) the region of dielectric material. A transparent layer of a material such as Indium Tin Oxide can be used to make ohmic contact between the semiconductor and the metallic electrode, as the metallic electrode is separated from physical contact with the semiconductor by one or more of the dielectric material and the transparent ohmic contact layer (e.g., ITO layer). The dielectric material can enhance total internal reflection of light and reduce an amount of light that is absorbed by the metallic electrode.Type: GrantFiled: September 22, 2010Date of Patent: September 27, 2011Assignee: Bridgelux, Inc.Inventors: Frank T. Shum, William W. So, Steven D. Lester

Patent number: 8022406Abstract: While suppressing the frequency of a signal line driver circuit, a blur of a moving image of a light-emitting device using a light-emitting transistor can be prevented, without reducing a frame frequency. A switching element is provided in a path of a current which flows between a source and a drain of a light-emitting transistor, and the light-emitting transistor is made not to emit light by turning off the switching element, whereby pseudo-impulse driving is performed. Switching of the switching element can be controlled by a scan line driver circuit. In a specific structural example, the light-emitting device includes, in a pixel, a light-emitting transistor, a first switching element which controls supply of a potential of a video signal to a gate of the light-emitting transistor, and a second switching element which controls a current which flows between a source and a drain of the light-emitting transistor.Type: GrantFiled: January 23, 2009Date of Patent: September 20, 2011Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventor: Tatsuya Honda

Patent number: 8022404Abstract: In the case where a material containing an alkaline-earth metal in a cathode, is used, there is a fear of the diffusion of an impurity ion (such as alkaline-earth metal ion) from the EL element to the TFT being generated and causing the variation of characteristics of the TFT. Therefore, as the insulating film provided between TFT and EL element, a film containing a material for not only blocking the diffusion of an impurity ion such as an alkaline-earth metal ion but also aggressively absorbing an impurity ion such as an alkaline-earth metal ion is used.Type: GrantFiled: June 16, 2008Date of Patent: September 20, 2011Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Satoshi Murakami, Mitsuhiro Ichijo, Taketomi Asami
