style="text-indent:25px">同樣的刻蝕條件，針對(duì)不同的刻蝕暴露面積，刻蝕的速率會(huì)有所不一樣。通常來(lái)說(shuō)，刻蝕面積越大，刻蝕的速率越慢，暴露面積越小，刻蝕的速率越快。所以在速率調(diào)試的過(guò)程中，需要使用尺寸相當(dāng)?shù)臉悠愤M(jìn)來(lái)調(diào)試，這樣調(diào)試的刻蝕速率參考意義比較大。氮化硅濕法刻蝕：對(duì)于鈍化層，另外一種受青睞的化合物是氮化硅?？梢杂靡后w化學(xué)的方法來(lái)刻蝕，但是不想其他層那樣容易。使用的化學(xué)品是熱磷酸。因酸液在此溫度下會(huì)迅速蒸發(fā)，所以刻蝕要在一個(gè)裝有冷卻蓋的密封回流容器中進(jìn)行。主要問(wèn)題是光刻膠層經(jīng)不起刻蝕劑的溫度和高刻蝕速率。因此，需要一層二氧化硅或其他材料來(lái)阻擋刻蝕劑。這兩個(gè)因素已導(dǎo)致對(duì)于氮化硅使用干法刻蝕技術(shù)。湖北氮化鎵材料刻蝕公司刻蝕是用化學(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(guò)程。</p><div

BOSCH工藝的原理是在反應(yīng)腔室中輪流通入鈍化氣體C4F8與刻蝕氣體SF6與樣品進(jìn)行反應(yīng)，工藝的整個(gè)過(guò)程是淀積鈍化層步驟與刻蝕步驟的反復(fù)交替。其中保護(hù)氣體C4F8在高密度等離子體的作用下分解生成碳氟聚合物保護(hù)層，沉積在已經(jīng)做好圖形的樣品表面。</p><p

style="text-indent:25px">在半導(dǎo)體制造中有兩種基本的刻蝕工藝：干法刻蝕和濕法腐蝕。干法刻蝕是把硅片表面曝露于氣態(tài)中產(chǎn)生的等離子體，等離子體通過(guò)光刻膠中開(kāi)出的窗口，與硅片發(fā)生物理或化學(xué)反應(yīng)（或這兩種反應(yīng)），從而去掉曝露的表面材料。干法刻蝕是亞微米尺寸下刻蝕器件的較重要方法。而在濕法腐蝕中，液體化學(xué)試劑（如酸、堿和溶劑等）以化學(xué)方式去除硅片表面的材料。濕法腐蝕一般只是用在尺寸較大的情況下（大于3微米）。濕法腐蝕仍然用來(lái)腐蝕硅片上某些層或用來(lái)去除干法刻蝕后的殘留物。ICP刻蝕設(shè)備能夠進(jìn)行(氮化鎵）、(氮化硅）、（氧化硅）、(鋁鎵氮）等半導(dǎo)體材料進(jìn)行刻蝕。湖北氮化鎵材料刻蝕公司</p><p
