摘要

節約能源及防止地球暖化成為世界各國關注的議題，促使具有環保、體積小、壽命長、耗電量低等優點之二極體(LED)漸受到重視，並成為21 世紀的新光源。自九十年代中期開始，GaN藍光LED已成為光電子產業應用之焦點，最關鍵問題之ㄧ就是亮度效率的改善，在GaN藍光LED 晶片技術方面，以材料與製程方法為技術重點，本研究嘗試歸納 TRIZ 創新流程中矛盾矩陣與創新法則來解決亮度效率的改善問題，以提高 GaN藍光LED 性能為發展目標，最後歸納出二十二個創新法則並提出四項改善策略，經一系列實驗驗證其改善在GaN藍光LED的亮度提升達 46%平均值，達到亮度效率提升之目標。

Since the energy-saving and the global warming effect are becoming the topics concerned all around the world, the light emitting diode(LED) with the benefits of environmental friendliness, tiny volume, long service life and low energy consumption seems to be the new light source in the 21st century. Since the mid-1990s, GaN Blue LED has been of great interest because of its potential for optoelectronic application. One of the critical problems in a conventional GaN Blue LED chip was increasing light efficiency. With respect to the LED technology, the variety of materials and the manufacturing variations are the key points. In this study, the means Contradiction matrix and the innovative principles based TRIZ innovation process concerned would be put forth in the project. Contradictions caused by transition actions were formulated and resolved with the guidance of inventive principles that suggested conceptual guidelines for technical contradiction. More than four useful ideas were developed with the aid of the inventive principles. Many ideas have proven excellent performers for light extraction up to a 46 percent increase in average. And it can be found the brightness improvement and heat dissipation could be solved simultaneously. As for the innovation process to produce GaN Blue LED, the target will be raising the efficiency of light extraction.
