摘要： A method for manufacturing light emitting device is provided. Firstly, provide a substrate. Then arrange a light emitting unit on the substrate. Next form at least one electrode and arrange at least one protective layer on the electrode. The protective layer is to prevent a phosphor layer following formed on the light emitting unit from covering the electrode. After forming the phosphor layer, flatten the phosphor layer and the protective layer. A part of the phosphor layer over the protective layer is removed. Thus the electrode is not affected by the phosphor layer and conductivity of the electrode is improved to resolve phosphor thickness and uniformity problems of the light emitting device. Therefore, the thickness of the light emitting device with LED is effectively reduced and stability of white color temperature control is significantly improved.

摘要： A method of manufacturing an oxynitride phosphor is revealed. A precursor is sintered under 0.1-1000 MPa nitrogen pressure for synthesis of an oxynitride phosphor. The general formula of the oxynitride phosphors is Ba3-XSi6O12N2:EuxBa3-XSi6O6N6:Eux or Ba3-XSi6O9N4:Eux (0.00001≦x≦5; 0.00001). Thus pure phosphor can be mass-produced.

摘要： The present invention relates to a light-emitting diode (LED) and a method for manufacturing the same. The LED comprises an LED die, one or more metal pads, and a fluorescent layer. The characteristics of the present invention include that the metals pads are left exposed for the convenience of subsequent wiring and packaging processes. In addition, the LED provided by the present invention is a single light-mixing chip, which can be packaged directly without the need of coating fluorescent powders on the packaging glue. Because the fluorescent layer and the packaging glue are not processed simultaneously and are of different materials, the stress problem in the packaged LED can be reduced effectively.
