Title: 脱ガス測定方法ならびにｅｕｖリソグラフィ装置および測定構成
IPC: H01L21/027
Filed: 2008-03-03
Abstract: 残留ガスの分析により、ＥＵＶ真空系、特にＥＵＶリソグラフィ装置における脱ガスを測定するための、残留ガスの分析前に脱ガスを誘起する方法が提案される。まさに低揮発性炭化水素も、ＥＵＶリソグラフィ装置（１０）の稼働開始時の光学コンポーネント（１５、１６、１８、１９）の汚染への無視できない影響を有することが判明しており、しかしこの低揮発性炭化水素は従来の方法では検出されない。表面活性化のための刺激ユニット（３２、３４）によって残留ガス分析のために脱ガスを誘起することにより、低揮発性炭化水素も、通常の残留ガス分析計（３１、３３）の検出限界を超える濃度内で残留ガス中に存在することが達成される。これにより、ＥＵＶリソグラフィ装置（１０）の内部空間が、高すぎる汚染を懸念する必要なく稼働を開始し得るために十分にきれいであるかどうかを、もっとより正確に予測し得ることが達成される。そのため実質的には、残留ガス分析の比較的高い感度が効果的に達成される。
