Description
・マスクが上面及び/又は下面をカバーすべき位置におけるマスキング材料のインクジェット印刷のような選択的堆積によって行われるか、又は
・マスクを形成しようとする上面及び/又は下面の全体にマスキング材料の層を堆積して、その後に、上面及び/又は下面に装飾パターン又は技術的パターンを形成しようとする位置においてマスキング層を除去することによって行われる。
・ 第1の層は、典型的には7〜15nmのオーダーである非常に薄い表面層28である。これは、驚くべきことに、イオン照射の影響をわずかしか受けないかまったく受けずにその結晶構造を保持する。この現象は、窒素イオンがサファイア試料26の表面に当たったときに、その窒素イオンは、最も低いエネルギー経路を経てサファイア試料26に浸透して、ケイ素の結晶構造のセルを通り抜けるというように説明することを試みることができる。
・ 次に、厚みが典型的には50〜60nmである第1のアモルファス層30がある。この第1のアモルファス層30は、窒素イオンがサファイア試料26の厚みの中に深く浸透するにしたがって寸法構成が小さくなる空洞32によって特徴づけられる。この現象は、窒素イオンがサファイア試料26の厚みの中に深く浸透するほど、その速度が低くなりサファイア試料26の結晶構造が被る損傷が小さくなるとして説明することができる。
・ 次に、空洞がなく厚みが約20〜30nmである第2のアモルファス層34がある。したがって、サファイアの結晶構造は、サファイア試料26の表面の下の約80〜100nmの深さまでイオン照射によって大きく破壊される。
・ 最後に、厚みが50〜60nmのオーダーである最終層36がある。その結晶性は、その体積全体にわたってサファイアがアモルファスにされることなく乱される。この最終層36を超えると、サファイアが体積38にある。
