Description
1.ステップ・モードでは、マスク・テーブルMTは基本的に静止状態に維持し、マスクの像を1回で、つまり1つの「フラッシュ」で標的部分Cに投影する。次に、ビームPBで異なる標的部分Cを露光できるよう、基板テーブルWTをXおよび/またはY方向にシフトさせる。
2.走査モードでは、基本的に同じシナリオが当てはまるが、所与の標的部分Cが1つの「フラッシュ」では露光しない。代わりに、マスク・テーブルMTは速度vで所与の方向(いわゆる「走査方向」、例えばY方向)に移動可能であり、したがって投影ビームPBがマスクの像を走査する。同時に、基板テーブルWTが速度V=Mvで同じ方向または反対方向に同時に移動し、ここでMはレンズPLの倍率(通常はM=1/4または1/5)である。この方法で、解像度を妥協せずに比較的大きい標的部分Cを露光することができる。
