孔罩

We also compared with experimental results by changing the aperture size of 54.7 degree mask.

模拟结果指出具54.7度斜角开孔的蒸镀遮罩与基板的距离必须缩短以提高蒸镀图形的解析度。

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 reason for the cutout in the bottom of the cowl, then, was to direct the spray of oil as well as to aid in cooling the engine.

为在罩的底部，然后开孔的原因，是直接的喷油以及帮助冷却发动机。

The main purposes of this study are to develop a method to control pollutant dispersion and to measure the control efficiency during the chamber preventative maintenance of a metal etcher.

实验以固定流量的1000 ppm追踪气体SF6在腔底连续释放，以了解反应腔的气罩效率或反应腔上方全开，在侧边视窗孔抽气时对污染物逸散的控制效率。

On the demand of the manufacture practice, we have designed the Testing System for Shadow Mask and developed the Image Testing Software, thus we also measured the geometry parameters of the Shadow Mask with the digital image processing technology.

本文根据生产实践的需求，对荫罩板测试系统进行了设计研究；开发了相应的图像测试软件，并利用数字图像处理技术对荫罩板网孔的几何参数进行了测量研究。

This paper focuses on the evenness problem which occurs after solving the blockage problem through using bubble plate to replace sieve plate.

重点研究了采用泡罩板取代筛板解决堵塞问题后出现的均匀性问题，多方案优化的结果是采用较大直径的泡罩，并且加装一块大孔均布板，可以满足稳定运行的要求。
