Description
と、熱処理中にアルカリイオンが成膜された半導体物質中に拡散し、膜特性の劣化を招くと考えられており、実質的にアルカリ金属酸化物を含有しないことや、フォトエッチング工程において使用される種々の酸、アルカリ等の薬品によって劣化しないような耐薬品性を有することが要求される。
さらにガラスの歪点が640℃以上、好ましくは650℃以上であれば、耐熱衝撃性に一層優れ、また熱収縮が小さくできるためにより好ましい。
X :ガラス肉厚(mm)
T1:参照波長3846cm-1における透過率(%)
T2:水酸基吸収波長3600cm-1付近における最小透過率(%)
さらに上記特性に加え、液相温度が1150℃以下(特に1130℃以下、さらには1100℃以下)、液相温度における粘度が105.4dPa・s以上(特に106.0dPa・s以上)であることが望ましい。この条件を満たすことにより、ダウンドロー法で板状に成形しても失透が発生せず、研磨工程を省略して生産コストを低減することが可能である。さらに10%HCl水溶液に80℃−24時間の条件で処理した時、その浸食量が10μm以下で、且つ、10%HCl水溶液に80℃−1時間の条件で処理した時、目視による表面観察で白濁、荒れが認められず、しかも130BHF溶液に20℃−30分間の条件で処理した時、その浸食量が0.8μm以下で、且つ、63BHF溶液に20℃−30分間の条件で処理した時、目視による表面観察で白濁、荒れが認められないことが望ましい。また比ヤング率が、27.5GPa/g・cm-3以上(特に29.0GPa・s以上)であることが望ましい。この条件を満たすことにより、ガラス基板のたわみ量を小さくすることができる。さらに102.5dPa・sの粘度におけるガラス融液の温度が1650℃以下であれば、溶融性も良好になる。
を0.6%以下、SnO2含有量を0.3%以下、β−OH値を0.2/mm以上にする
ことができ、失透が起こりにくく、また溶融性に優れたものとなる。
X :ガラス肉厚(mm)
T1:参照波長3846cm-1における透過率(%)
T2:水酸基吸収波長3600cm-1付近における最小透過率(%)
失透性は、得られた基板ガラス10m2分について、失透物の有無を顕微鏡により観察した。
