Description
Toshio Nishida et al., "GaN-free transparent ultraviolet light-emitting diodes", 2003, Appl. Phys. Lett., vol.82, 1299 西田敏夫等,「バルクAlN基板上に形成したUV−LEDの高電流注入特性」,第51回応用物理学関係連合講演会講演予稿集,2004年3月,p.409
まず、HVPE法により成長させたAlN結晶を鏡面研磨し、その後に鏡面研磨によるダメージ層を除去することによって得られた口径2インチのAlN基板を50枚用意した。ここで、50枚のAlN基板はそれぞれ厚さが400μmであり、AlN基板の表面は方位(0001)から2°オフした面である。
Claims (2)
- 検出角度10°でのX線光電子分光法によるAlN基板の表面の光電子スペクトルにおいて、Al2s電子とN1s電子のピーク面積の比(Al2s電子のピーク面積/N1s電子のピーク面積)が0.65以下であることを特徴とする、AlN基板。
- AlN基板を、硝酸、リン酸および酢酸からなる群から選択された少なくとも1種からなり、その濃度が0.5質量%以上の酸溶液に40秒以上浸漬させることによって、検出角度10°でのX線光電子分光法によるAlN基板の表面の光電子スペクトルにおいて、Al2s電子とN1s電子のピーク面積の比(Al2s電子のピーク面積/N1s電子のピーク面積)を0.65以下にすることを特徴とする、AlN基板の洗浄方法。
