style="text-indent:25px">反應(yīng)離子刻蝕（RIE）是當(dāng)前常用技術(shù)路徑，屬于物理和化學(xué)混合刻蝕。在傳統(tǒng)的反應(yīng)離子刻蝕機(jī)中，進(jìn)入反應(yīng)室的氣體會被分解電離為等離子體，等離子體由反應(yīng)正離子、自由基、反應(yīng)原子等組成。反應(yīng)正離子會轟擊硅片表面形成物理刻蝕，同時被轟擊的硅片表面化學(xué)活性被提高，之后硅片會與自由基和反應(yīng)原子形成化學(xué)刻蝕。這個過程中由于離子轟擊帶有方向性，RIE技術(shù)具有較好的各向異性。目前先進(jìn)集成電路制造技術(shù)中用于刻蝕關(guān)鍵層的刻蝕方法是高密度等離子體刻蝕技術(shù)。傳統(tǒng)的RIE系統(tǒng)難以使刻蝕物質(zhì)進(jìn)入高深寬比圖形中并將殘余生成物從中排出，因此不能滿足0.25μm以下尺寸的加工要求，解決辦法是增加等離子體的密度。高密度等離子體刻蝕技術(shù)主要分為電子回旋加速振蕩（ECR）、電容或電感耦合等離子體（CCP/ICP）、雙等離子體源等。在硅材料刻蝕當(dāng)中，硅針的刻蝕需要用到各向同性刻蝕，硅柱的刻蝕需要用到各項異性刻蝕。安徽MEMS材料刻蝕服務(wù)</p><p
