style="text-indent:25px">刻蝕是使用化學(xué)或者物理方法有選擇地從硅片表面去除不需要材料的過程，常用的設(shè)備為刻蝕機(jī)等。通常的晶圓加工流程中，刻蝕工藝位于光刻工藝之后，有圖形的光刻膠層在刻蝕中不會(huì)受到腐蝕源的明顯侵蝕，從而完成圖形轉(zhuǎn)移的工藝步驟。為在硅片表面材料上復(fù)制掩膜圖案，刻蝕需要滿足一定的參數(shù)，主要有：刻蝕速率、刻蝕剖面、刻蝕偏差和選擇比等?？涛g速率指刻蝕過程中去除硅片表面材料的速度；刻蝕剖面指的是刻蝕圖形的側(cè)壁形狀，通常分為各向同性和各向異性剖面；刻蝕偏差指的是線寬或關(guān)鍵尺寸間距的變化，通常由橫向鉆蝕引起；選擇比指的是同一刻蝕條件下兩種材料刻蝕速率比，高選擇比意味著不需要的材料會(huì)被刻除?？涛g是用化學(xué)或物理方法有選擇的從硅片表面去除不需要的材料的過程。安徽深硅刻蝕材料刻蝕版廠家</p><p

style="text-indent:25px">干法刻蝕也可以根據(jù)被刻蝕的材料類型來分類。按材料來分，刻蝕主要分成三種：金屬刻蝕、介質(zhì)刻蝕、和硅刻蝕。介質(zhì)刻蝕是用于介質(zhì)材料的刻蝕，如二氧化硅。接觸孔和通孔結(jié)構(gòu)的制作需要刻蝕介質(zhì)，從而在ILD中刻蝕出窗口，而具有高深寬比（窗口的深與寬的比值）的窗口刻蝕具有一定的挑戰(zhàn)性。硅刻蝕（包括多晶硅）應(yīng)用于需要去除硅的場(chǎng)合，如刻蝕多晶硅晶體管柵和硅槽電容。金屬刻蝕主要是在金屬層上去掉鋁合金復(fù)合層，制作出互連線。廣東省科學(xué)院半導(dǎo)體研究所。安徽深硅刻蝕材料刻蝕版廠家</p><p
