查询词典 etch

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。

To carve,cut,or etch into a block or surface used for printing.

雕版在用于印刷的材料或其表面雕刻、镌划。

The dislocation distribution of Cd1-xZnxTe crystal with Vertical Bridgman Method had been analyzed by observing the etch pits density.

使用观察位错蚀坑密度方法研究了垂直布里奇曼法生长的Cd1-xZnxTe单晶体位错分布规律。

As most of us knows , chemic material must be used for wafer manufacturing , such as etch , pervasion and etc .

诚如我们所知，芯片的生产过程中一定会用到化工原料，比如刻蚀，扩散等等。

The pure screw dislocation is easily etched along the steps that the dislocation terminates. Consequently a small Ga-polar plane is formed to prevent further vertical etching,resulting in an etch pit shaped like an inverted truncated hexagonal pyramid at the terminal chiasma of two surface steps.

纯螺位错易于沿着由它结束的表面阶梯被腐蚀，形成一个小的Ga极性面以阻止进一步的纵向腐蚀，因而其腐蚀坑是位于两个表面阶梯交结处的截底倒六棱椎。

Proper etchants were chosen to etch different planes of KDP crystal.

利用化学腐蚀法对KDP晶体的不同晶面进行了腐蚀，得到了清晰的位错蚀坑。

The process is used in GaAs PHEMT volume-production and easy to get good uniformity of pinch-off and darin current by selective etch stop layer technology.

GaAs PHEMT外延材料具有电流密度大、器件效率高等优点，在高频大功率GaAs MMIC工艺制作中，PHEMT材料已广泛应用于GaAs单片集成电路中。

Meguiar's Quik Detailer removes fresh contaminants before they have a chance to bond or etch into the surface .

在它们有机会聚集或渗入到表层之前，它可以去除新落上去的灰尘。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
