    • In the presentation, I'm going to cover first, what is dry etching, second, where dry etching is used in fabrication, third, etch profile control and selectivity definitions, and finally, why use plasma for etching.

      在演講中,我將首先介紹什麼是幹蝕刻,其次介紹幹蝕刻在製造中的應用,第三介紹蝕刻曲線控制和選擇性定義,最後介紹為什麼要使用等離子體進行蝕刻。

    • third, etch profile control and selectivity definitions; and finally, why use plasma for etching.

      本課程的其他單元還將介紹納米制造中使用的其他兩個主要工藝,即沉積(鋪膜工藝)和光刻(圖案化亞光(通常是摺疊抗蝕劑薄膜)工藝)。

    • Physical sputtering tends to be used for anisotropic, uh, etching but it has an issues of damage, low selectivity, redeposition.

      我們喜歡氬氣,因為它不產生化學反應,而且在相同的功率條件下,我們往往能得到氬氣,氬氣和其他物質能產生更高的離子通量。

    • Physical sputtering tends to be used for anisotropic etching, but it has issues of damage, low selectivity, redeposition.

      物理濺射通常用於各向異性蝕刻,但存在損壞、低選擇性和再沉積等問題。

    • The etch depth controls selectivity means, what is the matte material, stopping material, allow losses.

      蝕刻深度控制選擇性意味著什麼?

    • The X depth controls selectivity needs.

      這就是所謂的巴赫進程。
