style="text-indent:25px">材料的濕法化學(xué)刻蝕，包括刻蝕劑到達材料表面和反應(yīng)產(chǎn)物離開表面的傳輸過程，也包括表面本身的反應(yīng)。如果刻蝕劑的傳輸是限制加工的因素，則這種反應(yīng)受擴散的限制。吸附和解吸也影響濕法刻蝕的速率，而且在整個加工過程中可能是一種限制因素。半導(dǎo)體技術(shù)中的許多刻蝕工藝是在相當緩慢并受速率控制的情況下進行的，這是因為覆蓋在表面上有一污染層。因此，刻蝕時受到反應(yīng)劑擴散速率的限制。污染層厚度常有幾微米，如果化學(xué)反應(yīng)有氣體逸出，則此層就可能破裂。濕法刻蝕工藝常常有反應(yīng)物產(chǎn)生，這種產(chǎn)物受溶液的溶解速率的限制。為了使刻蝕速率提高，常常使溶液攪動，因為攪動增強了外擴散效應(yīng)。多晶和非晶材料的刻蝕是各向異性的。然而，結(jié)晶材料的刻蝕可能是各向同性，也可能是各向異性的，它取決于反應(yīng)動力學(xué)的性質(zhì)。晶體材料的各向同性刻蝕常被稱作拋光刻蝕，因為它們產(chǎn)生平滑的表面。各向異性刻蝕通常能顯示晶面，或使晶體產(chǎn)生缺陷。因此，可用于化學(xué)加工，也可作為結(jié)晶刻蝕劑。二氧化硅濕法刻蝕：較普通的刻蝕層是熱氧化形成的二氧化硅。</p><div
