Description
[0001] 本出願は、2009年4月27日に出願された米国仮出願第61/172,904号の利益を主張し、その全体が参照により本明細書に組み込まれる。
CD = k1λ/NAPS (1)
1.ステップモードにおいては、マスクテーブルMTおよび基板テーブルWTを基本的に静止状態に保ちつつ、放射ビームに付けられたパターン全体を一度にターゲット部分C上に投影する(すなわち、単一静的露光)。その後、基板テーブルWTは、基板の平面内で移動され、それによって別のターゲット部分Cを露光することができる。ステップモードにおいては、露光フィールドの最大サイズによって、単一静的露光時に結像されるターゲット部分Cのサイズが限定される。
2.スキャンモードにおいては、マスクテーブルMTおよび基板テーブルWTを同期的にスキャンする一方で、放射ビームに付けられたパターンをターゲット部分C上に投影する(すなわち、単一動的露光)。マスクテーブル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(縮小)拡大率および像反転特性によって決めることができる。スキャンモードにおいては、露光フィールドの最大サイズによって、単一動的露光時のターゲット部分の幅(非スキャン方向)が限定される一方、スキャン動作の長さによって、ターゲット部分の高さ(スキャン方向)が決まる。
3.別のモードにおいては、プログラマブルパターニングデバイスを保持した状態で、マスクテーブルMTを基本的に静止状態に保ち、また基板テーブルWTを動かす、またはスキャンする一方で、放射ビームに付けられているパターンをターゲット部分C上に投影する。このモードにおいては、通常、パルス放射源が採用されており、さらにプログラマブルパターニングデバイスは、基板テーブルWTの移動後ごとに、またはスキャン中の連続する放射パルスと放射パルスとの間に、必要に応じて更新される。この動作モードは、前述の型のプログラマブルミラーアレイといったプログラマブルパターニングデバイスを利用す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。
[0083] 発明の概要及び要約の項目は、発明者が想定するような本発明の1つ以上の例示的実施形態について述べることができるが、全部の例示的実施形態を述べることはできず、従って本発明及び請求の範囲をいかなる意味でも制限しないものとする。
