Abstract
Description
まず、本発明の一実施形態に係る成膜装置1の全体構成について、図1を参照しながら説明する。図1は、本発明の一実施形態に係る成膜装置1の縦断面を示す。本実施形態では、成膜装置1としてALD成膜装置を一例に挙げる。なお、成膜装置1は、ガスの作用により半導体ウェハ(以下、「ウェハW」という。)に成膜等の所定の処理を行う処理装置の一例である。
1.ステージ2上に成膜のための高い置換効率を得るための極小化した反応室(処理空間U)がある。
2.ウェハWの受け渡しのための大容量であるボトム空間Bが、処理空間U(ステージ2)の下方に位置している。
3.処理空間Uの外周に排気ポート13の排気空間がリング状に存在する。
次に、本実施形態に係るカバー部材3について、図3〜図5を参照しながら詳細に説明する。カバー部材3は、ステージ2の外縁部に設けられ、チャンバC内をステージ2の上部の処理空間Uとステージ2の下部のボトム空間Bとに区画する。
処理空間Uの圧力をP2とし、ボトム空間Bの圧力をP1とし、バッファ空間Vの圧力をP3とする。このとき、制御部7は、P1〜P3の圧力の関係が、P2>P3及びP1>P3になるように、排気装置65及びガス供給部6を制御する。これにより、カバー部材3とステージ2との間のバッファ空間V内のガスを排気ポート13側へとスムーズに排気することができる。
