Abstract
Description
以下に、本発明の一実施形態について説明する。
本発明の一実施形態に係る処理装置としての基板処理装置100の処理炉202の構成について、図1を参照しながら説明する。
図2を参照して、除害装置248a,248bの構成について説明する。
図3を参照して、コントローラ240の制御構成について説明する。
次に、基板処理装置100の基板処理工程について詳述する。基板処理工程の実施をする場合には、主制御部25は、記憶部28のプログラム格納領域33に格納されているプロセスレシピを実行する。
複数枚のウエハ200がボート217に装填(ウエハチャージ)されると、ボート217は、ボートエレベータ115によって処理室201内に搬入(ボートロード)される。このとき、シールキャップ219は、Oリング220bを介してマニホールド209の下端を気密に閉塞(シール)した状態となる。
処理室201内、すなわち、ウエハ200が存在する空間が大気圧から所定の圧力(真空度)となるように、補助ポンプ244及びメインポンプ246によって真空排気(減圧排気)されて除害装置248a又は除害装置248bに排気される。この際、処理室201内の圧力は、圧力センサ245で測定され、この測定された圧力情報に基づきAPCバルブ242が、フィードバック制御される。補助ポンプ244、メインポンプ246及び除害装置248a又は除害装置248bは、少なくともウエハ200に対する処理が終了するまでの間は常時作動させた状態を維持する。
そして、バルブ245c,243c,245d,243dを開き、ガス供給管230a,230bからN2ガスを処理室201内へ供給し、排気ユニット310から排気する。N2ガスはパージガスとして作用する。これにより、処理室201内がパージされる。
処理室201内の温度が予め設定された処理温度に安定すると、次の2つのステップ、すなわち、ステップ1~2を順次実行する。
このステップでは、処理室201内のウエハ200に対し、HCDSガスを供給する。
ステップ1が終了した後、処理室201内のウエハ200、すなわち、ウエハ200上に形成された第1の層に対してNH3ガスを供給する。NH3ガスは熱で活性化されてウエハ200に対して供給されることとなる。
上述した2つのステップを非同時に、すなわち、同期させることなく行うサイクルを所定回数行うことにより、ウエハ200上に、所定膜厚のSiN膜を形成することができる。なお、上述のサイクルを1回行う際に形成される第2の層(SiN層)の厚さを所定の膜厚よりも小さくし、第2の層を積層することで形成されるSiN膜の膜厚が所定の膜厚になるまで、上述のサイクルを複数回繰り返すのが好ましい。
成膜処理が完了した後、バルブ245c,243c,245d,243dを開き、ノズル230a,230bからN2ガスを処理室201内へ供給し、排気管231から排気する。N2ガスはパージガスとして作用する。これにより、処理室201内がパージされ、処理室201内に残留するガスや反応副生成物が処理室201内から除去される(パージ)。その後、処理室201内の雰囲気が不活性ガスに置換され(不活性ガス置換)、処理室201内の圧力が常圧に復帰される(大気圧復帰)。
ボートエレベータ115によりシールキャップ219が下降され、プロセスチューブ203の下端が開口される。そして、処理済のウエハ200が、ボート217に支持された状態で、プロセスチューブ203の下端からプロセスチューブ203の外部に搬出される(ボートアンロード)。処理済のウエハ200は、ボート217より取出される(ウエハディスチャージ)。
排気コントローラ15の動作について図4に基づいて説明する。
次に、除害装置248a,248bのメンテナンス時間が基板処理装置100のプロセス処理時間よりも短い場合の主制御部25の処理シーケンスについて、図5を参照して説明する。
本実施形態によれば、以下に示す1つ又は複数の効果が得られる。
図7は、他の構成例を示す図である。本構成例では、排気管231、補助ポンプ244、メインポンプ246及び除害装置248により、排気ユニット310が構成される。除害装置248は、上述した三方バルブ249a,249b、除害装置248a,248bにより構成されている。
