Abstract
【解決手段】熱酸化膜61及びBPSG膜63を有するウエハWに向けてHFガスを供給して、BPSG膜63を選択的にエッチングし、次いで、ウエハWに向けてNH3ガスを供給して、SiO2とフッ酸との反応に基づいて発生する残留物64のH2SiF6とNH3ガスとを反応させてNH4F及びSiF4を発生させ、さらに、NH4Fを昇華させる。
【選択図】図3
Description
SiO2+4HF → SiF4+2H2O↑
SiF4+2HF → H2SiF6
残留物(H2SiF6)が発生する。
H2SiF6+2NH3 → 2NH4F+SiF4↑
NH4F(フッ化アンモニウム)とSiF4(四フッ化珪素)とを発生させる。NH4Fは昇華しやすい物質であり、雰囲気温度を常温より多少高く設定すれば、昇華するため、容易に除去することができる。
H2SiF6+Q(熱エネルギ) → 2HF↑+SiF4↑
HFとSiF4を発生させる。
