Description
(1)熱処理工程で成膜された半導体物質中にアルカリイオンが拡散する事態を防止するため、ほとんどアルカリ金属酸化物を含まないこと、つまり無アルカリガラスであること(ガラス組成中のアルカリ酸化物の含有量が0.5mol%以下であること)、
(2)ガラス板を低廉化するため、生産性に優れること、特に溶融性や耐失透性に優れること、
(3)LTPS(low temperature poly silicon)プロセスにおいて、ガラス板の熱収縮を低減するため、歪点が高いこと。
β-OH=(1/X)log(T1/T2)
X:板厚(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(%)
