style="text-indent:25px">等離子刻蝕的原理可以概括為以下幾個(gè)步驟：1、在低壓下，反應(yīng)氣體在射頻功率的激發(fā)下，產(chǎn)生電離并形成等離子體，等離子體是由帶電的電子和離子組成，反應(yīng)腔體中的氣體在電子的撞擊下，除了轉(zhuǎn)變成離子外，還能吸收能量并形成大量的活性基團(tuán)（Radicals）2、活性反應(yīng)基團(tuán)和被刻蝕物質(zhì)表面形成化學(xué)反應(yīng)并形成揮發(fā)性的反應(yīng)生成物3、反應(yīng)生成物脫離被刻蝕物質(zhì)表面，并被真空系統(tǒng)抽出腔體。在平行電極等離子體反應(yīng)腔體中，被刻蝕物是被置于面積較小的電極上，在這種情況，一個(gè)直流偏壓會(huì)在等離子體和該電極間形成，并使帶正電的反應(yīng)氣體離子加速撞擊被刻蝕物質(zhì)表面，這種離子轟擊可較大加快表面的化學(xué)反應(yīng)，及反應(yīng)生成物的脫附，從而導(dǎo)致比較高的刻蝕速率，正是由于離子轟擊的存在才使得各向異性刻蝕得以實(shí)現(xiàn)。等離子會(huì)釋放帶正電的離子來(lái)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)。</p><div
