前記透明導電膜と前記金属膜とが重なった部分に、前記透明導電膜及び前記金属膜のそれぞれに対し密着性を有して前記透明導電膜と前記金属膜との間の導通を妨げないバッファ膜を有する導電体であって、
前記バッファ膜が、透明金属酸化物で形成されること、あるいは、前記透明導電膜及び前記金属膜の夫々に結合する官能基を備えた有機物であることを特徴とするものである。
基材上に形成された銀ナノワイヤを含む透明導電膜上に、前記透明導電膜と次工程に形成される金属膜のそれぞれと密着性を有して前記透明導電膜と前記金属膜との間の導通を妨げないバッファ膜を形成する工程と、
前記バッファ膜上に前記金属膜の少なくとも一部を形成する工程と、
を有する導電体の製造方法であって、
前記バッファ膜を、透明金属酸化物で形成すること、あるいは、前記透明導電膜及び前記金属膜の夫々に結合する官能基を備えた有機物で形成することを特徴とするものである。
また本発明では、前記バッファ膜に対して熱処理工程を施すことが好ましい。これにより、より効果的に透明導電膜と金属膜間の密着性を向上させることができる。
図1(a)に示す導電体1は、透明基材2と、透明基材2の上面2aに形成された透明導電膜3と、透明導電膜3上に形成されたバッファ膜4と、バッファ膜4上に形成された金属膜5とを有して構成される。
なおこの明細書において、「透明」「透光性」とは可視光線透過率が50%以上(好ましくは80%以上)の状態を指す。
また、有機物に対して熱処理が施されていることが密着性をより効果的に向上させるうえで好ましい。熱処理は、100℃前後で数分〜数十分行うことが好適である。この熱処理は、上記の化学式7や化学式8に示すトリアジン化合物を用いたバッファ膜4の形成工程中に施されるものであってもよいし、あるいは、バッファ膜4の形成工程後(金属膜5の成膜前、成膜中、成膜後のいずれであってもよい)に施されるものであってもよい。
金属膜5をCu膜で形成することが好ましい。
さらにレジスト層9を除去することで図6に示す導電体1が完成する。
いずれの導電体も、透明基材上に銀ナノワイヤを含む透明導電膜が形成された共通の導電基材を使用し、さらに金属膜として膜厚が150nmのCu膜を成膜した。
なお、実施例1、2については、透明導電膜の上面を逆スパッタしていない。
