Another approach in enhancing the light extraction efficiency of AlGaInP LED was accomplished using a surface roughening process. In this process, the Au(170 nm)/AuBe(260 nm)/Au(170 nm) ohmic contact layers were first deposited on the GaP window layer. After the alloy annealing process (480°C for 10 min), the Be atoms will diffuse into the GaP top layer and form non-uniform clusters. The LED samples were then immersed into a mixture 3H3PO4:1H2O2:1H2O solution for 6 min, resulting in a rough GaP surface. The luminous intensity of the AlGaInP LED can increase from 42 to 50 mcd, that is, an 18% enhancement can be achieved via the present non-photolithography surface roughening process.Keywords: LED, AlGaInP, Cu substrate, Reflector, Surface roughening
在实验的第二部份是开发磷化镓窗口层之粗化制程，我们是藉由正面金/铍欧姆接触电极之熔合制程，使铍扩散至磷化镓层，同时利用铍渗入磷化镓造成之特殊组成，可形成不均匀之蚀刻阻挡，而在磷化镓表面形成粗化，我们发现480℃、10分钟的熔合制程，加上浸泡磷化镓蚀刻溶液6分钟，可将四元发光二极体之发光亮度由42 mcd 提升到50 mcd，经由此无光罩粗化制程可将亮度提升18%，明显提升磷化铝铟镓发光二极体之外部量子效率。
