Title: (JA) 型の製造方法および型を用いた反射防止膜の製造方法
Abstract: front page image
(JA)

本発明のモスアイ用型の製造方法は、Alの含有量が99.99質量%未満のAl基材を用意する工程(a)と、Al基材を部分的に陽極酸化することによって、複数の微細な凹部を有するポーラスアルミナ層を形成する工程(b)と、工程(b)の後に、ポーラスアルミナ層を、アノードインヒビターを含むエッチング液に接触させることによって、ポーラスアルミナ層の複数の微細な凹部を拡大させる工程(c)と、工程(c)の後に、さらに陽極酸化することによって、複数の微細な凹部を成長させる工程(d)とを包含する。
