style="text-indent:25px">介質(zhì)刻蝕是用于介質(zhì)材料的刻蝕，如二氧化硅。干法刻蝕優(yōu)點是：各向異性好，選擇比高，可控性、靈活性、重復性好，細線條操作安全，易實現(xiàn)自動化，無化學廢液，處理過程未引入污染，潔凈度高。缺點是：成本高，設備復雜。干法刻蝕主要形式有純化學過程（如屏蔽式，下游式，桶式），純物理過程（如離子銑），物理化學過程，常用的有反應離子刻蝕RIE，離子束輔助自由基刻蝕ICP等。干法刻蝕方式比較多，一般有：濺射與離子束銑蝕，等離子刻蝕（PlasmaEtching），高壓等離子刻蝕，高密度等離子體（HDP）刻蝕，反應離子刻蝕（RIE）。另外，化學機械拋光CMP，剝離技術等等也可看成是廣義刻蝕的一些技術。干法刻蝕種類比較多，包括光揮發(fā)、氣相腐蝕、等離子體腐蝕等。</p><div
