Description
本発明のモールドのエッチング装置においては、前記モールドが回転可能であることが好ましい。
本発明のモールドのエッチング方法においては、前記モールドを回転させることが好ましい。
通常レンズで絞り込まれたレーザー光の強度は、図1に示すようなガウス分布形状を示す。このときスポット径は1/e2で定義される。一般的にフォトレジストの反応は、E=hν(E:エネルギー、h:プランク定数、ν:波長)で表されるエネルギーを吸収することよって反応が開始される。したがって、その反応は、光の強度には強く依存せず、むしろ光の波長に依存するため、光の照射された部分(露光部分)は、ほぼ全て反応が生じることになる。このため、フォトレジストを使った場合は、スポット径に対して忠実に露光されることになる。これは、露光精度を重視する半導体等の分野では良い特性と言える。
