図1に示すように基板保持部としてのボート217は、複数枚、例えば25~200枚のウエハ200を、水平姿勢で、かつ、互いに中心を揃えた状態で垂直方向に整列させて多段に保持(支持)するように、すなわち、間隔を空けて配列させるように構成されている。ボート217は、例えば石英やSiC等の耐熱性材料により構成される。ボート217の下部には、例えば石英やSiC等の耐熱性材料により構成される断熱板218が多段に支持されている。この構成により、ヒータ207からの熱がシールキャップ219側に伝わりにくくなっている。但し、本実施形態はこのような形態に限定されない。例えば、ボート217の下部に断熱板218を設けずに、石英やSiC等の耐熱性材料により構成される筒状の部材として構成された断熱筒を設けてもよい。
次にプラズマ発光部について、図1と図2を用いて説明する。
反応管203には、図1に示すように処理室201内の雰囲気を排気する排気管231が設けられている。排気管231には、処理室201内の圧力を検出する圧力検出器(圧力検出部)としての圧力センサ245及び排気用のバルブ(圧力調整部)としてのAPC(Auto Pressure Controller)バルブ244を介して、真空排気装置としての真空ポンプ246が接続されている。APCバルブ244は、真空ポンプ246を作動させた状態で弁を開閉することで、処理室201内の真空排気及び真空排気停止を行うことができ、更に、真空ポンプ246を作動させた状態で、圧力センサ245により検出された圧力情報に基づいて弁開度を調節することで、処理室201内の圧力を調整することができるように構成されている。主に、排気管231、APCバルブ244、圧力センサ245により、排気系が構成される。真空ポンプ246を排気系に含めて考えてもよい。排気管231は、反応管203に設ける場合に限らず、ノズル249a及びノズル249bと同様にマニホールド209に設けてもよい。
マニホールド209の下方には、マニホールド209の下端開口を気密に閉塞可能な炉口蓋体としてのシールキャップ219が設けられている。シールキャップ219は、マニホールド209の下端に垂直方向下側から当接されるように構成されている。シールキャップ219は、例えばSUS等の金属により構成され、円盤状に形成されている。シールキャップ219の上面には、マニホールド209の下端と当接するシール部材としてのOリング220bが設けられている。
図3に示すように、制御部(制御装置)であるコントローラ121は、CPU(Central Processing Unit)121a、RAM(Random Access Memory)121b、記憶装置121c、I/Oポート121dを備えたコンピュータとして構成されている。RAM121b、記憶装置121c、I/Oポート121dは、内部バス121eを介して、CPU121aとデータ交換可能なように構成されている。コントローラ121には、例えばタッチパネル等として構成された入出力装置122が接続されている。
上述の基板処理装置を用い、半導体装置(デバイス)の製造方法の工程の一つとして、基板上に膜を形成するプロセス例について、図4を用いて説明する。以下の説明において、基板処理装置を構成する各部の動作はコントローラ121により制御される。
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、シャッタ開閉機構115sによりシャッタ219sが移動させられて、マニホールド209の下端開口が開放される(シャッタオープン)。その後、図1に示すように、複数枚のウエハ200を支持したボート217は、ボートエレベータ115によって持ち上げられて処理室201内へ搬入(ボートロード)される。この状態で、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の下端をシールした状態となる。
処理室201の内部、すなわち、ウエハ200が存在する空間が所望の圧力(真空度)となるように、真空ポンプ246によって真空排気(減圧排気)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244がフィードバック制御される。真空ポンプ246は、少なくとも後述する成膜ステップが終了するまでの間は常時作動させた状態を維持する。
その後、ステップS3,S4,S5,S6を順次実行することで成膜ステップを行う。
ステップS3では、処理室201内のウエハ200に対して原料ガスを供給する。
原料ガス供給ステップが終了した後、処理室201内のウエハ200に対して第1ガスとしての光励起させた第1ガスを供給する(S5)。
上述したステップS3,S4,S5,S6をこの順番に沿って非同時に、すなわち、同期させることなく行うことを1サイクルとし、このサイクルを所定回数(n回)、すなわち、1回以上行うことにより、ウエハ200上に、所定組成及び所定膜厚のSiO膜を形成することができる。上述のサイクルは、複数回繰り返すことが好ましい。すなわち、1サイクルあたりに形成されるSiO層の厚さを所望の膜厚よりも小さくし、SiO層を積層することで形成されるSiO膜の膜厚が所望の膜厚になるまで、上述のサイクルを複数回繰り返すことが好ましい。
上述の成膜処理が完了したら、ガス供給管232c,232dのそれぞれから不活性ガスを処理室201内へ供給し、排気管231から排気する。これにより、処理室201内が不活性ガスでパージされ、処理室201内に残留する第1ガス等が処理室201内から除去される(不活性ガスパージ)。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:S8)。
その後、ボートエレベータ115によりシールキャップ219が下降されて、マニホールド209の下端が開口されるとともに、処理済のウエハ200が、ボート217に支持された状態でマニホールド209の下端から反応管203の外部に搬出(ボートアンロード)される。ボートアンロードの後は、シャッタ219sが移動させられ、マニホールド209の下端開口がOリング220cを介してシャッタ219sによりシールされる(シャッタクローズ)。処理済のウエハ200は、反応管203の外部に搬出された後、ボート217より取り出されることとなる(ウエハディスチャージ)。なお、ウエハディスチャージの後は、処理室201内へ空のボート217を搬入するようにしてもよい。
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。
(a)発光管249e内のプラズマ生成条件(ガス種、ガス圧力、高周波電力、周波数など)を変えることで、プラズマ発光の光量や波長を制御することができ、光照射されるガスの光励起状態や光励起される活性種の生成量を制御することが可能となる。
(b)発光源による処理室201の中心への光照射により、光励起される活性種をウエハ中央部で直接生成することができ、ウエハへの活性種の供給効率を高めることが可能となる。
(c)プラズマ発光の光量や波長を制御することで、光励起される活性種の生成分布をウエハ上部で調整することができ、ウエハ処理の面内均一性を図ることが可能となる。
