Abstract
Description
複数のモジュールをそれぞれ制御する複数のサブコントローラと、
前記複数のモジュールに現在設定されているシステムファイルを格納する第1格納部と、前記複数のモジュールに対するシステムファイルのアップロード又はダウンロードの履歴を履歴情報として格納する第2格納部とを備えた記憶部を有するメインコントローラと、を有するシステムであって、
前記メインコントローラは、前記複数のサブコントローラとの間でシステムファイルを送受信した際に、送受信したシステムファイルと、前記第1格納部に格納されているシステムファイルとの比較結果に応じて、送受信したシステムファイルを前記第1格納部に格納すると共に、前記システムファイルの履歴情報を前記第2格納部に格納する技術が提供される。
メインコントローラ242からは、搬送系コントローラ244に対して、搬送モジュールの駆動指示が発せられる。そして、搬送系コントローラ244からの指示に従いつつ、ポッド110がロードポート114に供給されると、ポッド搬入搬出口112がフロントシャッタ113によって開放される。ロードポート114上のポッド110はポッド搬送装置118によって筐体111の内部へポッド搬入搬出口112を通して搬入され、回転式ポッド棚105の指定された棚板117へ載置される。ポッド110は回転式ポッド棚105で一時的に保管された後、ポッド搬送装置118により棚板117からいずれか一方のポッドオープナ121に搬送されて載置台122に移載されるか、若しくはロードポート114から直接載置台122に移載される。
指定枚数のウエハ200がボート217に装填されると、ボート217は、搬送系コントローラ244からの指示に従って動作するボートエレベータ115によって上昇されて、処理炉202内に形成される処理室201に装入(ボートロード)される。ボート217が完全に装入されると、ボートエレベータ115のシールキャップ129は、処理炉202のマニホールドの下端を気密に閉塞する。
その後は、処理室201内は、圧力コントローラ246bからの指示に従いつつ、所定の成膜圧力(真空度)となるように真空排気装置によって真空排気される。この際、処理室201内の圧力は圧力センサで測定され、この測定された圧力情報に基づき圧力調整装置がフィードバック制御される。また、処理室201内は、温度コントローラ246aからの指示に従いつつ、所定の温度となるようにヒータによって加熱される。この際、処理室201内の温度が所定の温度(成膜温度)となるように、温度検出器としての温度センサが検出した温度情報に基づきヒータへの通電具合がフィードバック制御される。続いて、搬送系コントローラ244からの指示に従いつつ、回転機構によるボート217及びウエハ200の回転を開始する。そして、所定の圧力、所定の温度に維持された状態で、ボート217に保持された複数枚のウエハ200に所定のガス(処理ガス)を供給して、ウエハ200に所定の処理(例えば成膜処理)がなされる。
ボート217に載置されたウエハ200に対する成膜工程が完了すると、搬送系コントローラ244からの指示に従いつつ、その後、回転機構によるボート217及びウエハ200の回転を停止させ、ボートエレベータ115によりシールキャップ129を下降させてマニホールドの下端を開口させるとともに、処理済のウエハ200を保持したボート217を処理炉202の外部に搬出(ボートアンロード)する。
そして、処理済のウエハ200を保持したボート217は、クリーンユニット134から吹出されるクリーンエア133によって極めて効果的に冷却される。そして、例えば150℃以下に冷却されると、ボート217から処理済のウエハ200を脱装(ウエハディスチャージ)してポッド110に移載した後に、新たな未処理ウエハ200のボート217への移載が行われる。
