Description
θ=sin-1{λ/(n*P)} (2)
Pmin=λ/NA (3)
によって表すことができる。λは放射Bの波長であり、NAはビームコンバイナ115の開口数である。
[0071] 1.ステップモード:サポート構造MTおよび基板テーブルWTが基本的に静止状態に維持され、放射ビームに付与されたパターン全体がターゲット部分Cに1回で投影される(すなわち単一静止露光)。次に、基板テーブルWTがX方向および/またはY方向にシフトされ、異なるターゲット部分Cが露光される。ステップモードでは、露光フィールドの最大サイズによって、単一静止露光でイメージングされるターゲット部分Cのサイズが制限される。
[0072] 2.スキャンモード:放射ビームに付与されたパターンがターゲット部分Cに投影されている間、サポート構造MTおよび基板テーブルWTが同期スキャンされる(すなわち単一動的露光)。サポート構造MTに対する基板テーブルWTの速度および方向は、投影システムPSの倍率(縮小率)および画像反転特性によって決まる。スキャンモードでは、露光フィールドの最大サイズによって、単一動的露光におけるターゲット部分の幅(非スキャン方向の幅)が制限され、また、スキャン運動の長さによってターゲット部分の高さ(スキャン方向の高さ)が決まる。
[0073] 3.その他のモード:プログラマブルパターニングデバイスを保持するべくサポート構造MTが基本的に静止状態に維持され、放射ビームに付与されたパターンがターゲット部分Cに投影されている間、基板テーブルWTが移動またはスキャンされる。このモードでは、通常、パルス放射源が使用され、スキャン中、基板テーブルWTが移動する毎に、あるいは連続する放射パルスと放射パルスの間に、必要に応じてプログラマブルパターニングデバイスが更新される。この動作モードは、上で参照したタイプのプログラマブルミラーアレイなどのプログラマブルパターニングデバイスを利用しているマスクレスリソグラフィに容易に適用することができる。
