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(lái)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(lái)；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(lái)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(lái)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(zhǎng)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(yè)堡局滲次微米線寬制程技術(shù)的要求，而正被大量使用。二氧化硅濕法刻蝕：較普通的刻蝕層是熱氧化形成的二氧化硅。浙江ICP材料刻蝕外協(xié)</p><p
