Description
被覆される基板表面上に構造化被覆部を形成する方法が、文献DE 102 22 609 B4に記載されている。この公知のプロセスは、剥離方法に関し、まず、被覆される基板表面に反転構造(negative structuring)を有する第1の層を設ける。次に、第2の層の各部分を上に担持する第1の層を最終的に少なくとも部分的に除去できるように、第2の層を該表面上に積層する。構造化被覆部は、蒸着ガラス物質(evaporation glass material)を含む第2の層を蒸着によって積層させることによって、公知の方法で形成される。
本発明が取り組む課題は、基板上における構造化被覆部の形成に関連する技術を向上させることである。
被覆される表面を有する基板を準備するステップと、
少なくとも1種類の蒸着被覆物質、具体的には、酸化アルミニウム、二酸化ケイ素、窒化ケイ素、または、二酸化チタンを、熱蒸着法および加法的構造化法によって上記被覆される基板表面上に積層することによって、該表面上に構造化被覆部を形成するステップとを含む、方法が提供される。上記構造化被覆部は、その全体または一部のみがプラズマ促進熱電子ビーム蒸着(plasma−enhanced thermal electron beam evaporation)によって形成される。
基板と、
該基板の被覆される表面上に少なくとも1種類の層物質を含んでなる第1の層であって、該表面の一つ以上の部分には第1の層が設けられておらず、かつ、第1の層が設けられた該表面上に反転構造が形成されている第1の層と、
該第1の層が設けられた表面上に少なくとも1種類の蒸着被覆物質、具体的には、酸化アルミニウム、二酸化ケイ素、窒化ケイ素、または、二酸化チタンを含んでなる第2の層とを有する被覆済み基板を備えた、半完成品が提供される。
(2)上記構造化被覆部の形成が、
上記被覆される基板表面上に少なくとも1種類の層物質を積層し、該基板表面の一つ以上の部分を積層された層物質を除去することによって露出させる、該基板表面上に反転構造を有する第1の層を形成するステップと、
上記少なくとも1種類の蒸着被覆物質を熱蒸着させることによって、少なくとも1種類の蒸着被覆物質の、第2の層を、上記第1の層を有する基板の表面上に積層するステップと、
上記第1の層を少なくとも部分的に除去するステップとを含む、反転構造を利用する構造化プロセス。
次に、好ましい例としての実施形態を用いて、図面を参照しながら、本発明について詳細に記載する。
