style="text-indent:25px">濕法刻蝕是將刻蝕材料浸泡在腐蝕液內(nèi)進(jìn)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(dá)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)，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(dá)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(kuò)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(kuò)散到溶液中，隨溶液被排出。</p><p style="text-indent:25px">干法刻蝕是芯片制造領(lǐng)域較主要的表面材料去除方法，擁有更好的剖面控制。干刻蝕法按作用機(jī)理分為：物理刻蝕、化學(xué)刻蝕和物理化學(xué)綜合作用刻蝕。物理和化學(xué)綜合作用機(jī)理中，離子轟擊的物理過程可以通過濺射去除表面材料，具有比較強(qiáng)的方向性。離子轟擊可以改善化學(xué)刻蝕作用，使反應(yīng)元素與硅表面物質(zhì)反應(yīng)效率更高。綜合型干刻蝕法綜合離子濺射與表面反應(yīng)的優(yōu)點(diǎn)，使刻蝕具有較好的選擇比和線寬控制。在集成電路制造過程中需要多種類型的干法刻蝕工藝，應(yīng)用涉及硅片上各種材料。被刻蝕材料主要包括介質(zhì)、硅和金屬等，通過與光刻、沉積等工藝多次配合可以形成完整的底層電路、柵極、絕緣層以及金屬通路等。同樣的刻蝕條件，針對不同的刻蝕暴露面積，刻蝕的速率會(huì)有所不一樣。</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(gè)重要的因素。在一些比率上，刻蝕硅會(huì)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(jìn)行下去會(huì)導(dǎo)致工藝無法控制。有時(shí)醋酸和其他成分被混合進(jìn)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(jìn)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。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。廣州Si材料刻蝕多少錢</p><p
