style="text-indent:25px">干刻蝕是一類較新型，但迅速為半導(dǎo)體工業(yè)所采用的技術(shù)。其利用電漿(plasma)來進(jìn)行半導(dǎo)體薄膜材料的刻蝕加工。其中電漿必須在真空度約10至0.001Torr的環(huán)境下，才有可能被激發(fā)出來；而干刻蝕采用的氣體，或轟擊質(zhì)量頗巨，或化學(xué)活性極高，均能達(dá)成刻蝕的目的。干刻蝕基本上包括離子轟擊與化學(xué)反應(yīng)兩部份刻蝕機(jī)制。偏「離子轟擊」效應(yīng)者使用氬氣(argon)，加工出來之邊緣側(cè)向侵蝕現(xiàn)象極微。而偏化學(xué)反應(yīng)效應(yīng)者則采氟系或氯系氣體(如四氟化碳CF4)，經(jīng)激發(fā)出來的電漿，即帶有氟或氯之離子團(tuán)，可快速與芯片表面材質(zhì)反應(yīng)。刪轎厚干刻蝕法可直接利用光阻作刻蝕之阻絕遮幕，不必另行成長阻絕遮幕之半導(dǎo)體材料。而其較重要的優(yōu)點(diǎn)，能兼顧邊緣側(cè)向侵蝕現(xiàn)象極微與高刻蝕率兩種優(yōu)點(diǎn)，換言之，本技術(shù)中所謂活性離子刻蝕已足敷頁堡局滲次微米線寬制程技術(shù)的要求，而正被大量使用。</p><p

style="text-indent:25px">氮化硅的干法刻蝕S13N4在半導(dǎo)體工藝中主要用在兩個(gè)地方。1、用做器件區(qū)的防止氧化保護(hù)層（厚約lOOnm）。2、作為器件的鈍化保護(hù)層。在這兩個(gè)地方刻蝕的圖形尺寸都比較大，非等向的刻蝕就不那么重要了?？涛gSi3N4時(shí)下方通常是厚約25nm的Si02，為了避免對(duì)Si02層的刻蝕，Si3N4與S102之間必須有一定的刻蝕選擇比。S13N4的刻蝕基本上與Si02和Si類似，常用CF4+0等離子體來刻蝕。但是Si-N鍵強(qiáng)度介于Si-Si與Si-0之間，因此使Si3N4對(duì)Si或Si02的刻蝕選擇比均不好。在CF4的等離子體中，Si對(duì)Si3N4的選擇比約為8，而Si3N4對(duì)Si02的選擇比只有2—3，在這么低的刻蝕選擇比下，刻蝕時(shí)間的控制就變得非常重要。除了CF4外，也有人改用蘭氟化氮(NF3)的等離子體來刻蝕Si3N4，雖然刻蝕速率較慢，但可獲得可以接受的Si3N4/Si02的刻蝕選擇比。濕法腐蝕仍然用來腐蝕硅片上某些層或用來去除干法刻蝕后的殘留物。山西Si材料刻蝕平臺(tái)</p><p
