style="text-indent:25px">反應(yīng)離子刻蝕：這種刻蝕過程同時兼有物理和化學(xué)兩種作用。輝光放電在零點幾到幾十帕的低真空下進(jìn)行。硅片處于陰極電位，放電時的電位大部分降落在陰極附近。大量帶電粒子受垂直于硅片表面的電場加速，垂直入射到硅片表面上,以較大的動量進(jìn)行物理刻蝕,同時它們還與薄膜表面發(fā)生強(qiáng)烈的化學(xué)反應(yīng)，產(chǎn)生化學(xué)刻蝕作用。選擇合適的氣體組分，不僅可以獲得理想的刻蝕選擇性和速度，還可以使活性基團(tuán)的壽命短，這就有效地阻止了因這些基團(tuán)在薄膜表面附近的擴(kuò)散所能造成的側(cè)向反應(yīng)，較大提高了刻蝕的各向異性特性。反應(yīng)離子刻蝕是超大規(guī)模集成電路工藝中比較有發(fā)展前景的一種刻蝕方法。</p><p style="text-indent:25px">在Si片上形成具有垂直側(cè)壁的高深寬比溝槽結(jié)構(gòu)是制備先進(jìn)MEMS器件的關(guān)鍵工藝，其各向異性刻蝕要求非常嚴(yán)格。高深寬比的干法刻蝕技術(shù)以其刻蝕速率快、各向異性較強(qiáng)、污染少等優(yōu)點脫穎而出，成為MEMS器件加工的關(guān)鍵技術(shù)之一。BOSCH工藝,又名TMDE(Time Multiplexed Deep Etching)工藝，是一個刻蝕—鈍化—刻蝕的循環(huán)過程，以達(dá)到對硅材料進(jìn)行高深寬比、各向異性刻蝕的目的。 BOSCH工藝的原理是在反應(yīng)腔室中輪流通入鈍化氣體C4F8與刻蝕氣體SF6與樣品進(jìn)行反應(yīng)，工藝的整個過程是淀積鈍化層步驟與刻蝕步驟的反復(fù)交替。其中保護(hù)氣體C4F8在高密度等離子體的作用下分解生成碳氟聚合物保護(hù)層，沉積在已經(jīng)做好圖形的樣品表面。深硅刻蝕是MEMS器件制作當(dāng)中一個很重要的工藝。</p><div
