  1. By increasing the h2 dilution ratio, it is found that atomic hydrogen can selectively etch amorphous phase and stabilize crystalline phase. from the study on the distance from substrate to catalyzer, choosing a proper distance can ensure the gas fully decomposed, while a relatively low substrate temperature can cause the nanocrystalline particles to lose mobility and keep their sizes. the pre - carbonization process can enhance the nucleation density and make the growth of high quality nanocrystalline p - sic films much easier

    實驗結果表明:隨著工作氣壓的減小,薄膜的晶粒尺寸有所減小;通過提高氫氣稀釋度,利用原子氫在成膜過程中起的作用,可以穩定結晶相併去除雜相;適當的熱絲距離能保證反應氣體充分分解,又使襯底具有較高的過冷度,是形成納米薄膜的重要條件;採用分步碳化法可以提高形核密度,有利於獲得高質量的納米- sic薄膜;襯底施加負偏壓可以明顯提高襯底表面的基團的活,因負偏壓產生的離子轟擊還能造成高的表面缺陷密度,形成更多的形核位置。
  2. The optimizing methods of main etching parameters, such as etching rate, uniformity and selectivity, were investigated by the orthogonal experiment, and these results can be used for setting main process parameters, adjusting them with a drifting from desired conditions, and optimizing etching selectivity

    應用正交實驗,進行了速率、均勻比等主要參數的優化,得出主要工藝參數的設置方法和理想條件漂移時的調整方法以及優化比的方案。
  3. Through the analysis, it is shown that : 1, while fabricating the grating, the principle of selecting the parameters is : the period should be as large as possible, the etching depth should be small and filling factor should approach to 0. 25. 2, if selecting the parameter combine the selecting principle and the requirement of concrete application, the space of selecting the parameter should be larger than before. 3, while the period to. 4a, the surface profile has no effect on the reflectivity

    通過分析發現: 1 、在製作有一定特的光柵時,光柵參數的原則為:周期的取值應盡量的大,深度的取值應盡量的小,占空比的取值應盡量靠近f = 0 . 25 ; 2 、以參數的原則結合製作的具體應用要求宋光柵的參數,則各個參數的優化空間更大; 3 、當光柵的周期t 0 . 4時,表面面形對反射率沒有影響; 4 、運用臨界周期點隨折射率的變化規律,可以避免由於光柵周期過大而出現一級衍射,從而導致製作失敗。
