style="text-indent:25px">刻蝕，英文為Etch，它是半導(dǎo)體制造工藝，微電子IC制造工藝以及微納制造工藝中的一種相當(dāng)重要的步驟。是與光刻相聯(lián)系的圖形化（pattern）處理的一種主要工藝。所謂刻蝕，實(shí)際上狹義理解就是光刻腐蝕，先通過光刻將光刻膠進(jìn)行光刻曝光處理，然后通過其它方式實(shí)現(xiàn)腐蝕處理掉所需除去的部分?？涛g是用化學(xué)或物理方法有選擇地從硅片表面去除不需要的材料的過程，其基本目標(biāo)是在涂膠的硅片上正確地復(fù)制掩模圖形。隨著微制造工藝的發(fā)展，廣義上來講，刻蝕成了通過溶液、反應(yīng)離子或其它機(jī)械方式來剝離、去除材料的一種統(tǒng)稱，成為微加工制造的一種普適叫法。對(duì)于二氧化硅刻蝕，氣體一般使用CF4和氧的混合劑。半導(dǎo)體材料刻蝕加工平臺(tái)</p><p
