Description
シリコン基板形成後、この基板に高速熱アニーリングを行ってパッシベーション層を形成する。パッシベーション層はシリコン基板表面の凹凸を低減できる。さらに、ゲート酸化層または界面形成の間、基板から重水素が拡散し、界面のダングリングボンドと結合でき、安定構造を形成する。これにより、キャリアの侵入を防止でき、素子特性を高めることが可能である。
任意の実際の実施形態の開発において、例えばシステムの要件もしくは制約、またはコマーシャルに準じて開発者の具体的な目標を達成するため、大量の実施詳細が必要であり、一実施形態を別のものに変更することを考慮すべきである。また、このような開発努力は複雑で多大な時間を必要とするものであるかもしれないが、当業者にとっては単なる日常業務であることを考慮すべきである。
本発明の実施形態を都合よく明瞭に説明する補助の目的のため、図面は不正確な比率の簡略化したものであることに留意すべきである。
