style="text-indent:25px">同樣的刻蝕條件，針對不同的刻蝕暴露面積，刻蝕的速率會有所不一樣。通常來說，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)試的過程中，需要使用尺寸相當(dāng)?shù)臉悠愤M(jìn)來調(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阻擋刻蝕劑。這兩個(gè)因素已導(dǎo)致對于氮化硅使用干法刻蝕技術(shù)。</p><p style="text-indent:25px">硅材料在MEMS器件當(dāng)中是很重要的一種材料。在硅材料刻蝕當(dāng)中，應(yīng)用于醫(yī)美方向的硅針刻蝕需要用到各向同性刻蝕，縱向和橫向同時(shí)刻蝕，硅柱的刻蝕需要用到各項(xiàng)異性刻蝕，主要是在垂直方向刻蝕，而橫向盡量少刻蝕。氮化鎵基超表面結(jié)構(gòu)當(dāng)中，氮化鎵材料的刻蝕需要使用氧化硅作為掩膜來刻蝕，而氧化硅的刻蝕需要使用Cr充當(dāng)硬掩模。所以工藝當(dāng)中，需要先在氮化鎵表面使用PECVD沉積一層氧化硅，采用剝離的方法在氧化硅表面生長一層Cr，使用ICP設(shè)備依次刻蝕氧化硅和氮化鎵。ICP刻蝕可以調(diào)節(jié)的刻蝕參數(shù)有：ICP 功率，功率值越大，等離子體密度越大，射頻功率，功率值越大，等離子體能量越大，物理濺射加強(qiáng)。GaN的刻蝕一般是采用氯氣和三氯化硼，氣體比例的變化可以調(diào)節(jié)物理轟擊和化學(xué)反應(yīng)的平衡。深硅刻蝕是MEMS器件制作當(dāng)中一個(gè)很重要的工藝。</p><div style="width:100%;text-align:
