Abstract
Description
本発明のガラス基板として、好適なガラス組成およびその特性を表1に示す。表中の各試料を次のようにして作製した。まず表中のガラス組成となるように、ガラス原料を調合し、白金ポットを用いて1600℃-24時間溶融した。次に、得られた溶融ガラスをカーボン板の上に流し出し、平板形状に成形した。得られたガラスについて、表中の特性を評価した。
[平均表面粗さRaの測定]
AFM(Veeco社製D3000、カンチレバー:Si)を用いて、10μm角の範囲を測定し、面内の平均表面粗さRaを算出した。具体的には、ガラス基板内の中央部と周辺部(基板端部から50mm内側)の9ヶ所について、表面粗さRaを測定し、その平均値を算出した。
[剥離帯電評価]
剥離帯電評価には、図1に示すような装置を用いた。この装置は以下の構成を有している。
(1)ガラス基板の化学処理面を下側にして支持台1に載置する。
(2)イオナイザ付きエアーガン5により、ガラス基板を10V以下に除電する。
(3)プレートを上昇させてガラス基板に接触させるとともに真空吸着させて、プレートとガラス基板を30秒間密着させる。
(4)プレートを下降させることでガラス基板を剥離し、ガラス基板中央部に発生する帯電量を表面電位計で連続的に測定する。
(5)(3)と(4)を繰り返し、計5回の剥離帯電評価を連続して行う。
(6)各測定における最大帯電量を求め、これらを積算して剥離帯電量とする。
[はり付き性評価]
未化学処理のガラス基板(試料No.3-1と同等品)と化学処理後のガラス基板(試料No.3-2~3-6)について、未化学処理面と化学処理面が向かい合うようにして重ね合わせた後、平坦なプレートの上に載置して10kgの加重を均等にかけ、30分放置した。また、比較のために、試料No.3-1についても同様の方法で評価を行った。次に、両ガラス基板を引き剥がし、すぐに剥がれたものを「○」、剥がれ難かったものを「△」、ガラス基板の破損なしに剥がすことができなかったものを「×」とした。
[評価結果]
表2から明らかなように、試料No.3-2~3-6は、ガラス基板の一方の表面(第一の表面)の平均表面粗さRaが0.5~1.0nmであるため、剥離帯電量が低く、はり付き性評価でガラス基板が破損しなかった。一方、試料No.3-1は、剥離帯電量が高く、はり付き性評価でガラス基板が破損した。なお、今回は、表1のNo.3の試料を用いて、各種評価を行ったが、その他の試料(No.1、2、4~8)でも同様の評価結果が得られると考えられる。
