Description
極等に透明導電膜が用いられ、透明導電膜としてITO膜が広く使用されている。ITO膜は、例えばスパッタリング法等の成膜プロセスを用いて、例えばガラス等の基板上に形成される。さらに、レジスト等をマスクにしてITO膜をエッチングすることで電極パタ−ンが形成される。このエッチング工程には湿式と乾式があるが、湿式ではエッチング液が使用される。
実施例1〜7、比較例1〜4
表1に実施例及び比較例のエッチング液を表1に従って調製した。
残渣除去性試験:図1に示した基板は、ガラス基板上にクロムをスパッタリングして成膜し、ポジ型感光性レジスト塗布し、露光、現像した後、湿式エッチングによってクロムをエッチングし、レジストを剥離したのち非晶質ITOを成膜した基板である。
図1に示した基板を40℃に保ったエッチング液にエッチング速度から算出されるエッチングに必要な最小時間(ジャストエッチ)の1.0倍または1.3倍の時間浸漬し、水洗した。電子顕微鏡でクロム及びガラス上の残渣を観察した。
結果を表2に示す。
