Description
反応性スパッタにより、TaCNO(TaONの酸素又は窒素のサイトを炭素に置換した半導体)薄膜と、比較のためにTaONの半導体薄膜を、石英基板上に作製した。スパッタ成膜条件を表1に示す。
反応性スパッタにより、NbCNO(NbONの酸素または窒素のサイトが炭素で置換された半導体材料)薄膜と、比較のためのNbON薄膜とを、石英基板上に作製した。スパッタ成膜条件を表2に示す。
実施例2で示したNbONおよびNbCNOが、単斜晶系のNbONを母相としていることを確認するため、反応性スパッタにより、スパッタ出力を小さくし成膜速度を落として、NbON薄膜を石英基板上に作製した。スパッタ成膜条件を表3に示す。
