- The second case is isotropic etching, and this is where we get the pure chemical etching, where you have undercut equal to the X-depth.
第二種情況是各向同性蝕刻，也就是我們所說的純化學蝕刻，在這種情況下，下切深度等於 X 深度。
- The second case is isotropic etching and this is where we get where it's a pure chemical etching where you have undercut equal to the etch depth.
好吧，我們來給 X 選擇性下個定義。

- They tend to be isotropic.
它們往往是各向同性的。
- It can be a lot faster in the etching than sputtering, but a lot of times we need something more than isotropic.
它的蝕刻速度比濺射快得多，但很多時候我們需要的不是各向同性。

- And the fluorine tend to be faster but more, uh, more, uh, isotropic than the chlorine and bromine.
CF4 化合物可以添加或不添加 CHF3，也可以添加氫。
- So that as, as one side I'm adding oxygen and fluorine and so in this case I'm going to have a lot more free fluorine going on and the, uh, this one X oxide but if at high pressures with the high fluorine case we're going to get we can actually get isotropic etching of oxide.
在低壓條件下，我們通常不會加入氧氣，而是加入氫氣或碳。

- And it eliminates damage, so no ions or electron bombardment, no charging, no UV, and we get no x directionality, it's going to be totally isotropic before the action goes.
它消除了破壞，是以沒有離子或電子轟擊，沒有充電，沒有紫外線，也沒有 X 方向性，在行動開始之前，它將是完全各向同性的。
