style="text-indent:25px">刻蝕工藝去除晶圓表面的特定區(qū)域，以沉積其它材料。“干法”（等離子）刻蝕用于形成電路，而“濕法”刻蝕（使用化學(xué)浴）主要用于清潔晶圓。干法刻蝕是半導(dǎo)體制造中較常用的工藝之一。開始刻蝕前，晶圓上會涂上一層光刻膠或硬掩膜（通常是氧化物或氮化物），然后在光刻時將電路圖形曝光在晶圓上?？涛g只去除曝光圖形上的材料。在芯片工藝中，圖形化和刻蝕過程會重復(fù)進(jìn)行多次。等離子刻蝕是將電磁能量（通常為射頻（RF））施加到含有化學(xué)反應(yīng)成分（如氟或氯）的氣體中實現(xiàn)。等離子會釋放帶正電的離子來撞擊晶圓以去除（刻蝕）材料，并和活性自由基產(chǎn)生化學(xué)反應(yīng)，與刻蝕的材料反應(yīng)形成揮發(fā)性或非揮發(fā)性的殘留物。離子電荷會以垂直方向射入晶圓表面。這樣會形成近乎垂直的刻蝕形貌，這種形貌是現(xiàn)今密集封裝芯片設(shè)計中制作細(xì)微特征所必需的。一般而言，高蝕速率（在一定時間內(nèi)去除的材料量）都會受到歡迎。</p><p style="text-indent:25px">早期的刻蝕技術(shù)為濕法刻蝕，就是將刻蝕材料浸泡在腐蝕液中進(jìn)行腐蝕的技術(shù)。這個過程是純化學(xué)腐蝕的過程。濕法刻蝕具有良好的選擇性，例如實驗室經(jīng)常采用磷酸來腐蝕鋁金屬化，而不會腐蝕金屬化層間的介質(zhì)層材料；半導(dǎo)體制造過程中用調(diào)配后的氫氟酸（加入NH4F緩沖液）來腐蝕二氧化硅，而不會對光刻膠造成過量的傷害。隨著半導(dǎo)體特征尺寸的不斷減小，濕法刻蝕逐漸**法刻蝕所替代。其原因在于濕法刻蝕是各向同性的，橫向刻蝕的寬度接近于縱向刻蝕的深度，因此會產(chǎn)生鉆蝕的現(xiàn)象，因此在小尺寸的制程中，濕法刻蝕的精度控制非常困難，并且可重復(fù)性差。干法刻蝕種類比較多，包括光揮發(fā)、氣相腐蝕、等離子體腐蝕等。</p><div

style="text-indent:25px">工藝所用化學(xué)物質(zhì)取決于要刻蝕的薄膜類型。介電刻蝕應(yīng)用中通常使用含氟的化學(xué)物質(zhì)。硅和金屬刻蝕使用含氯成分的化學(xué)物質(zhì)。在工藝中可能會對一個薄膜層或多個薄膜層執(zhí)行特定的刻蝕步驟。當(dāng)需要處理多層薄膜時，以及刻蝕中必須精確停在某個特定薄膜層而不對其造成損傷時，刻蝕工藝的選擇比就變得非常重要。選擇比是兩個刻蝕速率的比率：被去除層的刻蝕速率與被保護(hù)層的刻蝕速率（例如刻蝕掩膜或終止層）。掩模或停止層）通常都希望有更高的選擇比。深硅刻蝕是MEMS器件制作當(dāng)中一個很重要的工藝。江西氮化硅材料刻蝕加工工廠</p><p
