查询词典 substrate

A novel V-shaped slot antenna with a small right-angle triangle of supplementary slot is presented. The slot clement is fed by an arrow-shaped terminal of a microstrip line printed on the other side of substrate, and its good impedance matching is achieved by adjusting the area of this triangular supplementary slot.

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。
