style="text-indent:25px">刻蝕工藝主要分為兩種：干法刻蝕和濕法刻蝕。干法刻蝕是通過等離子氣與硅片發(fā)生物理或化學(xué)反應(yīng)（或結(jié)合物理、化學(xué)兩種反應(yīng)）的方式將表面材料去除，主要用于亞微米尺寸下刻蝕，由于具有良好的各向異性和工藝可控性已被普遍應(yīng)用于芯片制造領(lǐng)域；濕法刻蝕通過化學(xué)試劑去除硅片表面材料，一般用于尺寸較大情況，目前仍用于干法刻蝕后殘留物的去除。金屬刻蝕主要應(yīng)用于金屬互連線、通孔、接觸金屬等環(huán)節(jié)。金屬互連線通常采用鋁合金，對鋁的刻蝕采用氯基氣體和部分聚合物。鎢在多層金屬結(jié)構(gòu)中常用作通孔的填充物，通常采用氟基或氯基氣體。江蘇材料刻蝕廠商刻蝕工藝：把未被抗蝕劑掩蔽的薄膜層除去，從而在薄膜上得到與抗蝕劑膜上完全相同圖形的工藝。</p><div

style="text-indent:25px">不過，芯片用單晶硅材料對材料內(nèi)部微缺陷率水平的要求較高，對加工環(huán)節(jié)的硅片表面顆粒和雜質(zhì)含量、表面平整度、應(yīng)力和機(jī)械強(qiáng)度等參數(shù)指標(biāo)有更為嚴(yán)格的要求。這些特性導(dǎo)致芯片用單晶硅材料的研發(fā)和生產(chǎn)，需要合理設(shè)計(jì)加工環(huán)節(jié)的工藝流程，同時(shí)也需要更先進(jìn)的加工設(shè)備。通過刻蝕用單晶硅材料在全球半導(dǎo)體產(chǎn)業(yè)鏈中“見縫插針”的，已經(jīng)擁有了穩(wěn)定的基本盤。向芯片用單晶硅材料賽道進(jìn)發(fā)，既是對創(chuàng)業(yè)初心的回歸，更是應(yīng)對下游需求變化的戰(zhàn)略調(diào)整，有望再一次驅(qū)動的強(qiáng)勁增長。材料是工業(yè)之母，隨著更多關(guān)鍵材料和設(shè)備的突破，中國終將在全球半導(dǎo)體產(chǎn)業(yè)鏈中揚(yáng)眉吐氣。</p><p style="text-indent:25px">刻蝕較簡單較常用分類是：干法刻蝕和濕法刻蝕。顯而易見，它們的區(qū)別就在于濕法使用溶劑或溶液來進(jìn)行刻蝕。濕法刻蝕是一個純粹的化學(xué)反應(yīng)過程，是指利用溶液與預(yù)刻蝕材料之間的化學(xué)反應(yīng)來去除未被掩蔽膜材料掩蔽的部分而達(dá)到刻蝕目的。其特點(diǎn)是：濕法刻蝕在半導(dǎo)體工藝中有著普遍應(yīng)用：磨片、拋光、清洗、腐蝕。優(yōu)點(diǎn)是選擇性好、重復(fù)性好、生產(chǎn)效率高、設(shè)備簡單、成本低。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。按照被刻蝕的材料類型來劃分，干法刻蝕主要分成三種：金屬刻蝕、介質(zhì)刻蝕和硅刻蝕。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

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。天津深硅刻蝕材料刻蝕公司</p><p
