查询词典 etch

A photo-tool is prepared which is a negative of the required etch image and is often a silver photographic emulsion plate.

一个照片工具准备这是一种必要的蚀刻负面形象往往是银感光乳剂板。

By adjusting the etch time and the concentration of acid in the process, different shapes of the tunnels can be obtained.

在栅极制作过程中通过改变酸液刻蚀的时间和浓度，可以腐蚀出不同形状的小孔。

The solidification step may be performed by any means known in the art other than by exposure of the etch-resist ink to actinic light and/or particle beam radiation sources.

的凝固步骤可能会以任何方式出名的艺术品，而不是由其他蚀刻曝光，抵制油墨作用光和/或粒子束辐射源进行。

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。

Preferably the amount of colorant in the etch-resistant ink is from 0.01 to 4 parts, more preferably from 0.1 to 3 parts and especially from 0.1 to 2 parts by weight.

最好在etch中的着色剂数量耐油墨是从0.01至4部分，从0.1到3件以上，最好，尤其是从0.1到2重量部分。

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。

This paper designs the communication system of radio telescope FAST.

针对500m口径球面射电望远镜FAST分布式控制系统的特点完成了其通信系统的设计。
