Outline of Final Research Achievements

Diamond is promising wide-gap semiconductor for the power devices operated under the hash environment owing to its excellent material property. In this study, the fabrication technique of nitride-based single layer and nitride/oxide stack layer structures on hydrogen-terminated diamond with surface hole conductive layer was explored as the first step. Next, the insulating and ferroelectric properties of these structures were investigated. Finally, these structures were adopted on diamond FET. As the results, the diamond FETs with on current (~-180 mA/mm) and breakdown voltage (~250 V) were successfully obtained.

Academic Significance and Societal Importance of the Research Achievements

パワースイッチングデバイス用に開発されていたダイヤモンドFETでは、大電流動作・高耐圧(低リーク電流)特性を得るために重要な高いキャパシタンス値と高いエネルギーギャップ値を同時に満たすデバイス構造を適応するのが困難であった。本研究で検討を行ったAlN及びAlN/Al2O3積層構造は、高いキャパシタンス値と高いエネルギーギャップ値を同時に得ることができ、これらの構造を用いたFETは、大電流動作・高耐圧特性を有す可能性が高いことが明らかとなった。また本研究対象であるダイヤモンドFETは、自動車・無線通信・宇宙開発等の幅広い分野で応用が可能であり、本研究はその礎を築くものに位置付けられる。
