Patent number: 7981705Abstract: In a method of manufacturing a vertical type light-emitting diode, a multilayered structure of group III nitride semiconductor compounds is epitaxy deposited on an irregular surface of a substrate. The substrate is then removed to expose an irregular surface of the multilayered structure corresponding to the irregular surface of the substrate. A portion of the exposed irregular surface of the multilayered structure is then etched for forming an electrode contact surface on which an electrode layer is subsequently formed. With this method, no specific planarized region is required on the irregular surface of the substrate. As a result, planarization treatment of the substrate is not necessary. The same substrate with the irregular surface can be reused for fabricating vertical and horizontal light-emitting diodes.Type: GrantFiled: July 30, 2010Date of Patent: July 19, 2011Assignee: Tekcore Co., Ltd.Inventors: Wei-Jung Chung, Shih-Hung Lee, Cheng-Hsien Li, Wen-Hsien Lin, Nien-Tze Yeh
