Abstract

　ダイヤモンドへの密着性は良く、外部からの機械的圧力の不均一さにより接触面が剥離してしまわない、ダイオード作成のプロセスにおいて、歩留まりを悪くしない、電流電圧特性の劣化を起こしにくいダイヤモンド半導体におけるショットキー電極及びその製造方法を提供する。 　基板上のダイヤモンド表面に形成された島状に点在するパターン Pt族合金薄膜があり、Pt族合金がPt５０～９９．９とRu及び又はIr０．１～５０質量％含んだPt族合金であること、又は基板上のダイヤモンド表面に形成された島状に点在するパターンPt又はPdから選ばれる金属薄膜があり、各Pt又はPdから選ばれる金属薄膜のすべてに、Pt又はPdから選ばれる金属薄膜上にRu, Ir, Rhから選ばれる金属薄膜が設けられた島状に点在するパターン電極からなるショットキー電極及びその製造方法。
