style="text-indent:25px">對(duì)于被刻蝕材料和掩蔽層材料（例如光刻膠）的選擇比SR可通過(guò)下式計(jì)算：SR=Ef/Er；其中，Ef為被刻蝕材料的刻蝕速率，Er為掩蔽層材料的刻蝕速率（如光刻膠）；根據(jù)這個(gè)公式，選擇比通常表示為一個(gè)比值，一個(gè)選擇比差的工藝這一比值可能是1:1，意味著被刻蝕的材料與光刻膠掩蔽層被去除地一樣快，而一個(gè)選擇比高的工藝這一比值可能是100:1，說(shuō)明被刻蝕材料的刻蝕速率為不要被刻蝕材料的（如光刻膠）刻蝕速率的100倍。廣東省科學(xué)院半導(dǎo)體研究所。介質(zhì)刻蝕是用于介質(zhì)材料的刻蝕，如二氧化硅，氮化硅。黑龍江硅材料刻蝕技術(shù)</p><p
