Description
本発明は、一般にマイクロエレクトロニクスデバイスに関し、特に、炭化珪素パワーデバイスおよびLEDに関する。
炭化珪素は比較的高い熱伝導性を有し、このためハイパワーデバイスやLEDの基板として使用される。しかしながら炭化珪素の低い移動度と、炭化珪素中での不純物の不完全なイオン化により、縦型デバイスでバックコンタクトとして使用された炭化珪素基板は、高い抵抗を有する。例えば、炭化珪素の300Vショットキダイオードの基板は、デバイスの全オン抵抗の約3分の2となる。基板抵抗に起因する寄生損失を低減する従来のアプローチは、基板材料の除去または薄膜化を含む。しかしながら、炭化珪素基板の場合、このアプローチは不利であると考えられる。なぜならば、効果的なヒートシンクである炭化珪素の除去を必要とするためである。このように、効果的なヒートシンクであって、デバイスの操作中に十分な損失を与えない低抵抗のバックコンタクトを有する基板を提供する技術が求められる。
