Description
(1)325℃より高い温度においてパルスDCにより堆積されたAZO膜は、膜の底面から上面まで柱状組織が延び、AZO膜の横方向径の小さい結晶粒(基板から膜の上面まで延びる、70nmより幅が狭い結晶粒)をもたらす、緻密な柱状結晶粒構造を示す、
(2)AZO膜の比抵抗は375nmより大きい膜厚に依存しない、
(3)膜は大きな電子易動度にかかわらず小さい光吸収を有する、
(4)膜は450℃まで電気的劣化がない改善された温度安定性を有する、及び
(5)膜は改善された化学的耐久性を有する、
を有する。
(1)325℃より高い温度においてパルスDCにより堆積されたAZO膜は、AZO膜の横方向結晶粒径を小さくする、柱状結晶粒構造(基板から膜の最上面まで延びる、70nmより直径が小さい柱状構造)を示す、
(2)AZO膜の比抵抗は375nmより大きい膜厚に依存しない、
(3)膜は大きな電子易動度にかかわらず小さい光吸収を有する、
(4)膜は熱的により安定であり、450℃まで電気的劣化がない、及び
(5)膜は改善された化学的耐久性を有する、
を有する。
ショートスロークライオポンプで真空引きされるPVDシステムに直径12.9インチ(32.8cm)の酸化物ターゲットを装着し、パルスDC電源でスパッタして、150mm径ガラス基板上にAZO膜を堆積した。基板をステンレス鋼ヒータに機械的にクランプし、裏面アルゴンで425℃まで加熱した。パルスDCスパッタリングは、パルス周波数に無関係に、スパッタ電圧をパルスデューティサイクルに線形依存して実効的に低下させることでターゲットアーキングが無くなることが分かった。
