Description
[0001] 本出願は、参照により全体が本明細書に組み込まれる、2011年2月18日に出願の米国特許仮出願第61/444,148号の利益を主張する。
上の式で、λは、使用される放射の波長であり、NAは、パターンを印刷するために使用される投影システムの開口数であり、k1は、レイリー定数とも呼ばれているプロセス依存調節係数であり、CDは、印刷されたフィーチャのフィーチャサイズ(またはクリティカルディメンジョン)である。式(1)から、フィーチャの最小印刷可能サイズは、露光波長λを短くすること、開口数NAを大きくすること、あるいはk1の値を小さくすること、の3つの方法によって縮小することができると言える。
板を保持するように構築された基板テーブルと、基板テーブル用のサポートブロックと、を備え、動作中、基板テーブルは、前記サポートブロックによって支持され、かつサポートブロックにクランプされ、サポートブロックの表面上には、クランプ中、基板テーブルに対して当接するための細長い要素のアレイが設けられ、基板テーブルの表面上には、クランプ中、サポートブロックに対して当接するための一組のバールが設けられ、細長い要素のアレイが延在する表面と一組のバールが延在する表面との間の距離は、それぞれが延在する表面から測定した細長い要素のアレイの高さと一組のバールの高さとの合計によって規定されることを特徴とする、基板サポートが提供される。
