Claims (1)
- 【特許請求の範囲】 1.テストパターンがその過程により同じ放射エネルギーであるが異なる照射時 間の系列により基板の表面上に設けられたフォトレジスト上に互いに接して多数 回映像され、そこですぐフォトレジストが現像されるフォトリソグラフィー過程 を監視する方法において、 テストパターンがフォトレジスト上に映像される放射エネルギーが、フォト レジスト上にパターンを映像するために監視されるべき過程において利用できる 放射エネルギーの小部分だけであることを特徴とするフォトリソグラフィー過程 を監視する方法。 2.請求項1記載のフォトリソグラフィー過程を監視する方法において、前記の テストパターンが前記のフォトレジスト上に投影されるフォトマスク上に形成さ れることを特徴とするフォトリソグラフィー過程を監視する方法。 3.請求項2記載のフォトリソグラフィー過程を監視する方法において、前記の テストパターンが放射線に対して不透過性であり且つフォトマスク上に設けられ た層内に設けられた、制限された放射線伝達を有する窓により形成されているこ とを特徴とするフォトリソグラフィー過程を監視する方法。 4.請求項3記載のフォトリソグラフィー過程を監視する方法において、前記の テストパターンがフォトマスク板上に設けられた放射線不透過性クロム層内の窓 のエッチングにより形成されていること、及び続いてクロム層が所望の制限され た放射線伝達が達成されるような厚さまで前記のフォトマスク板上に堆積される ことを特徴とするフォトリソグラフィー過程を監視する方法。
