上記成膜条件で膜厚5、10、20nmのITO膜が得られる。
方式:エレクトロンビーム(EB)蒸着
材料:SiO2タブレット
圧力:2×10−3Pa
電圧:5kV
電流:100mA
成膜レート:0.5nm/sec
上記成膜条件で膜厚5、10、20、40nmのSiO2膜が得られる。
電源:RF電源(13.56MHz)
RFパワー:100W
SiH4:5SCCM
N2:100SCCM
成膜温度:100℃
成膜圧力:100Pa
成膜レート:0.2nm/sec
上記成膜条件で膜厚5、10、20、40nmのSiNx膜が得られる。
上記のようにして得られた各膜は、以下の実施例で述べるような硫化水素暴露試験で、反射率の劣化はなかった。
第1スパッタ室1のターゲット1bに、Agを主成分として0.55at%(1.0wt%)のAu、0.27at%(0.3wt%)のSnを添加したAg系合金ターゲット、第2スパッタ室2のターゲット2bにITO(10wt%SnO2)ターゲットを、それぞれセットした。
第1スパッタ室1のターゲット1bに、実施例1と同様に、Agを主成分として0.55at%(1.0wt%)のAu、0.27at%(0.3wt%)のSnを添加したAg系合金ターゲット、第3スパッタ室3のターゲット3bにSiターゲットをそれぞれセットした。
第1スパッタ室のターゲット1bに、Agを主成分として0.55at%(1.0wt%)のAu、0.27at%(0.3wt%)のSnを添加したターゲット、第3スパッタ室のターゲット3bにSiターゲットをそれぞれセットした。
実施例1記載のITOキャップ層(5nm)/Ag系合金膜(150nm)からなる2層膜を大気中、250℃で1時間アニール処理した。図10にアニール前後の反射率(波長:300〜800nm)を示す。アニール処理することにより、反射率が2〜4%程度向上した。その理由として、ITOキャップ層の透過率が改善されること、また、アニール処理によりAg系合金膜の結晶化が促進されて、表面の平坦性がよくなり、その結果、反射率が向上することが考えられる。
