According to the present invention, a thick metallic protective film layer with a thickness of at least 10 microns is formed on the lateral and/or bottom sides of the vertical GaN LED to protect the element against external impact and to easily separate the chip. Further, a metallic substrate is used instead of a sapphire substrate to efficiently release the generated heat to the outside when the element is operated, so that the LED can be suitable for a high-power application and an element having improved optical output characteristics can also be manufactured. A metallic support layer is formed to protect the element from being distorted or damaged due to impact.Type: ApplicationFiled: October 21, 2005Publication date: January 10, 2008Applicants: SEOUL OPTO-DEVICE CO., LTD., POSTECH FOUNDATIONInventor: Jong Lam Lee

Patent number: 7306960Abstract: The invention concerns a light-emitting diode chip comprising a radiation-emitting active region and a window layer. To increase the luminous efficiency, the cross-sectional area of the radiation-emitting active region is smaller than the cross-sectional area of the window layer available for the decoupling of light. The invention is further directed to a method for fabricating a lens structure on the surface of a light-emitting component.Type: GrantFiled: December 19, 2005Date of Patent: December 11, 2007Assignee: Osram GmbHInventors: Georg Bogner, Siegmar Kugler, Ernst Nirschl, Raimund Oberschmid, Karl-Heinz Schlereth, Olaf Schoenfeld, Norbert Stath, Gerald Neumann

Patent number: 7282736Abstract: (Object) In a light-emitting device, it is preferable that a surface of a film below a light-emitting element has flatness. Therefore, treatment such as planarization of a surface of a film is performed after forming the film. The present invention proposes a structure of a light-emitting device that can make the foregoing planarization easier. (Solving Means) The same layer as a wiring formed on a first film is used to manufacture a second film. Herewith, a portion of the first film below a light-emitting element can be prevented from being etched to form unevenness at a surface of the first film during the formation of the wiring. In addition, a surface of a third film is made higher by providing the second film to enable local planarization.Type: GrantFiled: December 10, 2003Date of Patent: October 16, 2007Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Satoshi Murakami, Noriko Miyagi
