fac快轴准直原理

fac快轴准直原理如下：

1、激光准直仪由半导体激光器及电源、小型单筒望远镜、孔径约1cm的圆光阑、四象限光电池、2个可正、负显示的小量程数字电压表、导轨和3个调节架组成。

2、半导体激光器用于产生红色激光，倒置望远镜用于对激光器发出的激光束进行扩束准直，圆光阑可起到控制光斑直径大小及获得近似的轴对称圆光束的双重作用，四象限光电池用于检测激光束中心相对其中心的位置。

3、由可见红光的半导体激光器配上单筒望远镜及合适孔径的圆光阑，经调节可形成一束与导轨轴平行且有一定截面积大小的基准光束。

Module的工程师主要分成两大类：制程（工艺）和设备。也就是所谓PE和EE。基本上无论哪个Module都会有这样的两类工程师。工作如下：

设备工程师主要负责的是机台的状况，他们要保持机台始终处于比较良好的Status，从而提高机台的利用率。TSMC在最忙的时候曾经把机台的利用率提到到了110%以上，这样就需要缩短机台设计的PM时间，缩短机台的Monitor时间，减小Down机的几率。

这样设备工程师的压力就很大。设备工程师的On Call通常就是来自于此。如果大家都是混得比较资深的EE，那由于晚上都有设备值班，小问题都能够被处理掉，而大问题也没法处理，可以第二天白天来做。但如果是一群没有足够经验的EE，那么每个人都只能专精几种机台。

结果就是遇到不熟悉的机台出问题，就只好Call人了。半导体,芯片,设计,版图,芯片,制造,工艺,制程,封装,测试，EE在Fab中待的时间要比PE长，有很多routine的工作，比如PM。EE的问题相对简单。

EE有很多机会接触有毒的气体、辐射和化学药品，也容易遭受侵害。Fab里很多耸人听闻传说中的主人公都是EE。记住一条Fab的铁律，任何不明身份的液体都可以默认为是HF溶液，千万不要去胡乱摸。此外特别的区域会有特别的注意事项，各自要注意。

EE主要和PE以及厂务（FAC）的弟兄打交道。不太会直接面对PIE这种Module比较讨厌的人物，也和TD的弟兄没有什么大的过节。由于是机台的使用者，Vendor会常常来和EE搞好关系，如果公司许可，可以有很多的饭局。酒量要锻炼。

EE的工作很累，但并不很复杂，如果加入了一个不错的集体，也可以过的很快活。硕士以及以上学历的弟兄一般不会有机会加入EE的行列，工科的本科/大专毕业生可以绰绰有余的胜任EE的工作。EE做久了如果没有什么兴趣可以想办法转去做PE，如果想赚钱，做Vendor也不错。
