Description
前記多重浮彫要素スタンプは、ナノ構造物が刻印された紫外線透過性板材を各々の要素スタンプに切断する工程と、前記要素スタンプを紫外線透過性板材に所定の間隔を維持しながら接着する工程とにより形成され、前記要素スタンプを接着する工程は、前記紫外線透過性板材の一側面に所定の間隔で浅い溝又は貫通孔を形成する工程と、この溝又は貫通孔に前記各要素スタンプを嵌め込む工程とを含むことを特徴とする。
また、電子ビームリソグラフィ工程などを利用してナノ構造物が刻印されたスタンプを、材料除去工程(ダイシング、エッチングなど)を利用して複数の要素スタンプに切断し、石英、ガラス、サファイア、ダイアモンドなどの紫外光透過材料からなる板材に接着させ、多重浮彫要素スタンプを製作することができる。
そして、予め作製された要素スタンプの接合位置を決めるためにスタンプ用板素材に浅い溝を彫り、この溝に前記要素スタンプを嵌め込んで多重浮彫要素スタンプを形成することができる。
また、素材に貫通孔を形成し、この貫通孔に予め作製された要素スタンプを嵌め込んで多重浮彫要素スタンプを形成することもできる。要素スタンプを嵌め込む前に、貫通孔に接着剤を入れておくと、要素スタンプは、貫通孔内で固定される。
