Description
また、本発明の他の態様は、半導体基板と、前記半導体基板上に所定の間隔を置いて互いに略平行に配置された複数のフィンと、複数の前記フィンの各々の両側面をゲート絶縁膜を介して挟むように形成されたゲート電極と、複数の前記フィンの厚さ方向に平行な側面、及び、複数の前記フィンのうちの両端に位置する2つの前記フィンの外側側面に形成されたエピタキシャル結晶成長を抑制する成長抑制層と、複数の前記フィンの少なくとも一部の側面上に形成されるエピタキシャル結晶からなる半導体層と、を有し、前記半導体層は、前記成長抑制層上には形成されておらず、前記外側側面の反対側の側面上に位置する領域には形成されていることを特徴とする半導体装置を提供する。
(半導体装置の構成)
図1は、本発明の第1の実施の形態に係る半導体装置の斜視図である。また、図2Aは、図1における断面II−IIを矢印の方向に見た断面図である。また、図2Bは、図2Aにおけるソース・ドレイン領域5およびそのエクステンション領域5aの図示を省略した断面図である。また、図3Aは、図1における断面III−IIIを矢印の方向に見た断面図である。また、図3Bは、図3Aにおけるソース・ドレイン領域5の図示を省略した断面図である。
図4〜12は、本発明の第1の実施の形態に係る半導体装置の製造方法を示す図である。
本発明の第1の実施の形態によれば、フィン3a、3b、3cの表面にエピタキシャル層9が形成されているために、フィン3a、3b、3cの全体のシリサイド化を防ぐことができる。さらに、フィン3a、3b、3cの厚さ方向に平行な側面、およびフィン3a、3cのそれぞれフィン3bと反対側の側面に成長抑制領域8を形成し、エピタキシャル層9の形成を抑えることにより、半導体装置1が隣接する他の素子と接触してショート等を起こすことを防止できる。
本発明の第2の実施の形態は、エピタキシャル層9を形成する工程で成長抑制領域8の代わりに成長抑制膜11を用いる点において第1の実施の形態と異なる。他の部材の構成等、第1の実施の形態と同様の点については説明を省略する。
図13〜16は、本発明の第2の実施の形態に係る半導体装置の製造方法を示す図である。
本発明の第2の実施の形態によれば、第1の実施の形態と同様に、フィン3a、3b、3cの表面にエピタキシャル層9が形成されているために、フィン3a、3b、3cの全体のシリサイド化を防ぐことができる。さらに、フィン3a、3b、3cの厚さ方向に平行な側面、およびフィン3a、3cのそれぞれフィン3bと反対側の側面に成長抑制膜11を形成し、エピタキシャル層9の形成を抑えることにより、半導体装置1が隣接する他の素子と接触してショート等を起こすことを防止できる。
本発明の第3の実施の形態は、エピタキシャル層9がフィン3a、3b、3cの間を完全に埋めない点において第1の実施の形態と異なる。他の部材の構成等、第1の実施の形態と同様の点については説明を省略する。
本発明の第3の実施の形態によれば、第1の実施の形態と同様に、フィン3a、3b、3cの表面にエピタキシャル層9が形成されているために、フィン3a、3b、3cの全体のシリサイド化を防ぐことができる。また、エピタキシャル層9の成長を第1の実施の形態よりも早い段階で止めるため、エピタキシャル層9が成長抑制領域8上に形成されることをより強く抑制することができる。そのため、半導体装置1が隣接する他の素子と接触してショート等を起こすことをより確実に防止できる。
本発明の第4の実施の形態は、エピタキシャル層9が成長抑制領域8の表面に形成される点において第1の実施の形態と異なる。他の部材の構成等、第1の実施の形態と同様の点については説明を省略する。
本発明の第4の実施の形態によれば、隣接する他の素子と接触しない範囲で成長抑制領域8上にエピタキシャル層9を形成することにより、フィン3a、3b、3cの全体のシリサイド化をより確実に防ぐことができる。
なお、本発明は上記各実施の形態に限定されず、発明の主旨を逸脱しない範囲内において種々変形実施が可能である。
