style="text-indent:25px">二氧化硅的干法刻蝕：刻蝕原理氧化物的等離子體刻蝕工藝大多采用含有氟碳化合物的氣體進行刻蝕。使用的氣體有四氟化碳(CF)、八氟丙烷(C，F(xiàn)8)、三氟甲烷(CHF3)等，常用的是CF和CHFCF的刻蝕速率比較高但對多晶硅的選擇比不好，CHF3的聚合物生產(chǎn)速率較高，非等離子體狀態(tài)下的氟碳化合物化學(xué)穩(wěn)定性較高，且其化學(xué)鍵比SiF的化學(xué)鍵強，不會與硅或硅的氧化物反應(yīng)。選擇比的改變在當(dāng)今半導(dǎo)體工藝中，Si02的干法刻蝕主要用于接觸孔與金屬間介電層連接洞的非等向性刻蝕方面。前者在S102下方的材料是Si，后者則是金屬層，通常是TiN（氮化鈦），因此在Si02的刻蝕中，Si07與Si或TiN的刻蝕選擇比是一個比較重要的因素。</p><p style="text-indent:25px">經(jīng)過前面的一系列工藝已將光刻掩膜版的圖形轉(zhuǎn)移到光刻膠上。為了制作元器件，需將光刻膠上的圖形進一步轉(zhuǎn)移到光刻膠下層的材料上。這個任務(wù)就由刻蝕來完成?？涛g就是將涂膠前所淀積的薄膜中沒有被光刻膠（經(jīng)過曝光和顯影后）覆蓋和保護的那部分去除掉，達到將光刻膠上的圖形轉(zhuǎn)移到其下層材料上的目的。光刻膠的下層薄膜可能是二氧化硅、氮化硅、多晶硅或者金屬材料。材料不同或圖形不同，刻蝕的要求不同。實際上，光刻和刻蝕是兩個不同的加工工藝，但因為這兩個工藝只有連續(xù)進行，才能完成真正意義上的圖形轉(zhuǎn)移，而且在工藝線上，這兩個工藝經(jīng)常是放在同一工序中，因此有時也將這兩個步驟統(tǒng)稱為光刻?？涛g，它是半導(dǎo)體制造工藝，微納制造工藝中的一種相當(dāng)重要的步驟。</p><div

style="text-indent:25px">等離子刻蝕是干法刻蝕中較常見的一種形式。一種或多種氣體原子或分子混合于反應(yīng)腔室中，在外部能量作用下（如射頻、微波等）形成等離子體。其原理是暴露在電子區(qū)域的氣體形成等離子體，由此產(chǎn)生的電離氣體和釋放高能電子組成的氣體，從而形成了等離子或離子，電離氣體原子通過電場加速時，會釋放足夠的力量與表面驅(qū)逐力緊緊粘合材料或蝕刻表面。一個等離子體干法刻蝕系統(tǒng)基本部件包括：發(fā)生刻蝕反應(yīng)的反應(yīng)腔、產(chǎn)生等離子體氣的射頻電源、氣體流量控制系統(tǒng)、去除生成物的真空系統(tǒng)?？涛g中會用到大量的化學(xué)氣體，通常用氟刻蝕二氧化硅，氯和氟刻蝕鋁，氯、氟和溴刻蝕硅，氧去除光刻膠。等離子會釋放帶正電的離子來撞擊晶圓以去除（刻蝕）材料，并和活性自由基產(chǎn)生化學(xué)反應(yīng)。珠海氮化鎵材料刻蝕平臺</p><p
