style="text-indent:25px">濕法刻蝕是將刻蝕材料浸泡在腐蝕液內(nèi)進行腐蝕的技術(shù)，是利用合適的化學(xué)試劑先將未被光刻膠覆蓋的晶片部分分解，然后轉(zhuǎn)成可溶的化合物達到去除的目的。濕法刻蝕是刻蝕的一種方法,其他的有干刻蝕，等離子刻蝕等。濕法刻蝕這種刻蝕技術(shù)主要是借助腐蝕液和晶片材料的化學(xué)反應(yīng)，遼寧氮化硅材料刻蝕廠家，遼寧氮化硅材料刻蝕廠家，遼寧氮化硅材料刻蝕廠家，因此我們可以借助化學(xué)試劑的選取、配比以及溫度的控制等來達到合適的刻蝕速率和良好的刻蝕選擇比。濕法刻蝕的過程：（1）反應(yīng)物擴散到欲被刻蝕材料的表面；（2）反應(yīng)物與被刻蝕材料反應(yīng)；（3）反應(yīng)后的產(chǎn)物離開刻蝕表面擴散到溶液中，隨溶液被排出。濕法腐蝕仍然用來腐蝕硅片上某些層或用來去除干法刻蝕后的殘留物。遼寧氮化硅材料刻蝕廠家</p><div

style="text-indent:25px">典型的硅刻蝕是用含氮的物質(zhì)與氫氟酸的混合水溶液。這一配比規(guī)則在控制刻蝕中成為一個重要的因素。在一些比率上，刻蝕硅會有放熱反應(yīng)。加熱反應(yīng)所產(chǎn)生的熱可加速刻蝕反應(yīng)，接下來又產(chǎn)生更多的熱，這樣進行下去會導(dǎo)致工藝無法控制。有時醋酸和其他成分被混合進來控制加熱反應(yīng)。一些器件要求在晶圓上刻蝕出槽或溝?？涛g配方要進行調(diào)整以使刻蝕速率依靠晶圓的取向。取向的晶圓以45°角刻蝕，取向的晶圓以“平”底刻蝕。其他取向的晶圓可以得到不同形狀的溝槽。多晶硅刻蝕也可用基本相同的規(guī)則。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。</p><div

style="text-indent:25px">反應(yīng)離子刻蝕：這種刻蝕過程同時兼有物理和化學(xué)兩種作用。輝光放電在零點幾到幾十帕的低真空下進行。硅片處于陰極電位，放電時的電位大部分降落在陰極附近。大量帶電粒子受垂直于硅片表面的電場加速，垂直入射到硅片表面上,以較大的動量進行物理刻蝕,同時它們還與薄膜表面發(fā)生強烈的化學(xué)反應(yīng)，產(chǎn)生化學(xué)刻蝕作用。選擇合適的氣體組分，不僅可以獲得理想的刻蝕選擇性和速度，還可以使活性基團的壽命短，這就有效地阻止了因這些基團在薄膜表面附近的擴散所能造成的側(cè)向反應(yīng)，較大提高了刻蝕的各向異性特性。反應(yīng)離子刻蝕是超大規(guī)模集成電路工藝中比較有發(fā)展前景的一種刻蝕方法。遼寧氮化硅材料刻蝕廠家</p><p
