Abstract
Description
微細凹凸表面構造の平均ピッチ及び平均深さを小さくするように第2のエッチングの加工時間は表1に示す可視光の場合の加工時間よりも短い。深紫外光の場合の微細凹凸表面構造の平均ピッチは65ナノメータであり、平均深さは200ナノメータである。
Claims (4)
- エッチングに先立ってマスクを形成することなく、石英ガラス基板に平均ピッチが50ナノメータから5マイクロメータの微細凹凸表面構造を製造する方法であって
イオンエッチング装置において、第1の電極に高周波電源を接続し第2の電極を接地し該石英ガラス基板を該第1の電極に接して配置した状態でアルゴンガスによって該石英ガラス基板にイオンエッチングを実施し、
その後に、同じ状態でトリフルオロメタン(CHF3)ガスまたはトリフルオロメタン(CHF3)及び酸素の混合ガスによって該石英ガラス基板に反応性イオンエッチングを実施する製造方法。 - 該混合ガスに対する酸素ガスの流量比率は0から50パーセントの範囲である請求項1に記載の製造方法。
- 該第1の電極を接地し該第2の電極に該高周波電源を接続し、該石英ガラス基板を該第1の電極に接して配置した状態でトリフルオロメタン(CHF3)ガスまたは酸素ガスによるラジカルエッチングを実施するステップをさらに含む請求項1または2に記載の製造方法。
- 反応性イオンエッチングを実施した後に該石英ガラス基板にウェットコーティングを実施するステップをさらに含む請求項1または2に記載の製造方法。
