氧化锡

Finally, a two-mask process was attempted to extend the same concept of the chip process. Here the mask of the contact aperture was replaced by the mask of the LED pad. After etching the SiO2 and ITO in the aperture region, a lateral etch of SiO2 was made to increase the ITO contact area. Although the forward voltage of the GaN LED shows a normal value, the process yield is still low and requires further study.

二道光罩制程延伸了三道光制程的理念，只是因为透明导电层的圆孔图形，是用电极的光罩去开的，所以蚀刻完二氧化矽膜及氧化铟锡膜后，必须再做二氧化矽膜的回蚀刻，让二氧化矽再内缩进去，以增加氧化铟锡和电极的接触面积，不会造成发光二极体的顺向电压提高，但因制程良率太低，所以还须要继续研究改善。

The third approach is about the concept of an ITO direct Ohmic contact structure on GaP window layer. The direct Ohmic contact structure is performed by the deposition of an AuBe diffused thin layer and the following activation process on the surface of a Mg-doped GaP window layer. The presence of this thin AuBe diffused layer yields the Be dominant metallic surface layer and significantly reduces the barrier height between the ITO and p-GaP layer. Via the modification of contact structure, not only the brightness was significantly increased but the reliability was comparable to the conventional LED without this structure.

第三个研究为一种具有直接欧姆接触在p型磷化镓窗层与氧化铟锡界面的制程方法，於本研究中并无习知砷化镓欧姆接触层的存在，我们利用金/金铍金属藉由热退火程序，使其金铍原子在磷化镓窗层表面形成具金属特性之薄膜层，降低磷化镓与氧化铟锡接触产生之接面能障；另外，该元件在氧化铟锡直接欧姆接触於磷化镓窗层下，除亮度具明显提升外，在稍大电流(20毫安培)元件可靠度测试下，亦未有明显衰减情形发生。

Guanine can quench the phthalhydrazidylazoacetylacetone's ECL in acid medium, and the linear concentration range of guanine relative to the ECL intensity is from 2.0×10~(-6) to 1.0×10~(-5) mol/L.The mechanism of phthalhydrazidylazoacetylacetone's ECL on the surface of ITO glass has been discussed according the experimental phenomenon.The phenomenon of ITO self-luminescence has also been studied.It has been found that the machanism of phthalhydrazidylazoacetylacetone on the surface of ITO in different medium is dissimilarity. The phenomenon of ITO self-luminescence may be caused by the interaction of the active oxygen element and ITO's surface.
