Description
(比較例1)
図3は、本発明の比較例1に係る半導体装置の模式的平面パターン構成図を示す。
また、図4は、本発明の比較例2に係る半導体装置の模式的平面パターン構成図を示す。
図1は、本発明の第1の実施の形態に係る半導体装置の模式的平面パターン構成図を示す。
図9は、本発明の第1の実施の形態に係る半導体装置において、活性領域AAi,AAi+1,…上に直接ソース電極20を形成し、半絶縁性基板10上にはエアブリッジ30の構造によるエアギャップ14を形成した半導体装置の模式的断面構造図を示す。図9も、図10の平面パターン構成図において、I−I線に沿って切断した断面構造に対応している。図1に示されたエアブリッジ30は、例えば、図9に示すように、非活性領域BA上の部分に形成される。また、図17は、図9に対応する模式的鳥瞰図を示す。エアギャップ14によって、エアブリッジ30の構造部分のソース電極20の寄生容量Cpを低減することができ、全体として、ソース電極20と基板10間の容量が低減される。
図10は、本発明の第1の実施の形態に係る半導体装置において、活性領域AA1, AA2,…および非活性領域BA上にソース電極20、ゲート電極24、ドレイン電極22を形成した半導体装置の模式的平面パターン構成図を示す。図1において、非活性領域BAは、図10に示すように、ストライプ状の活性領域AA1,AA2,…の間にストライプ状に配置される。
図7は、本発明の第1の実施の形態に係る半導体装置において、半絶縁性基板10にイオン注入によって、活性領域AAi,AAi+1を形成する工程を説明する模式的断面構造図を示す。図7において、基板10は半絶縁性基板であり、活性領域AAi,AAi+1を、例えば、シリコンイオン(Si+)のイオン注入によって形成する。非活性領域BAは、もともとの半絶縁性基板10を利用することができる。
図12は、本発明の第1の実施の形態に係る半導体装置において、活性領域AAi-1,AAi,AAi+1,…を半導体基板10で形成し、非活性領域BAをイオン注入で形成する例を説明する模式的鳥瞰図を示す。非活性領域BAの形成時に使用するイオン種としては、例えば窒素イオンなどを適用することができる。或いはまた、重イオンなどのイオン種を用いるイオン注入によって、結晶を破壊することで、非活性領域BAを形成することも可能である。或いはまた、非活性領域BAの予定部分を予めメサエッチングなどで形成し、その後絶縁物を充填することで、非活性領域BAを形成することもできる。
図13は、本発明の第1の実施の形態に係る半導体装置において、半導体装置の周辺部をメサ領域MAで形成し、デバイス領域DA内の非活性領域BAもメサ領域MAで形成したエアギャップ14を有する例を説明する模式的断面構造図を示す。図13の形成方法によれば、メサ領域MAで周辺の分離領域とデバイス領域DA内の非活性領域BAを同時に形成することができる。
図14は、本発明の第1の実施の形態に係る半導体装置において、半導体装置の周辺部をメサ領域MAで形成し、デバイス領域DA内の非活性領域BAをイオン注入で形成した例を説明する模式的断面構造図を示す。デバイス領域DA内の非活性領域BAをイオン注入で形成する場合、使用するイオン種としては、例えば窒素イオンなどを適用することができる。或いはまた、重イオンなどのイオン種を用いるイオン注入によって、結晶を破壊することで、非活性領域BAを形成することも可能である。
図15は、本発明の第1の実施の形態に係る半導体装置において、活性領域AAを半導体基板10で形成し、非活性領域BAをエアブリッジ30の構造を有するエアギャップ14で形成した例を説明する模式的断面構造図を示す。図9および図17に示される構造と活性領域AAと非活性領域BAの関係が逆になった構造に対応している。
図16は、本発明の第1の実施の形態に係る半導体装置において、デバイス領域DA内の活性領域AAi,AAi+1,…および非活性領域BAを共にイオン注入で形成した例を説明する模式的鳥瞰図を示す。
図2は、本発明の第1の実施の形態の変形例に係る半導体装置の模式的平面パターン構成図を示す。
図5は、本発明の第2の実施の形態に係る半導体装置の模式的平面パターン構成図を示す。本発明の第2の実施の形態に係る半導体装置は、ゲート電極24とドレイン電極22がフィッシュボーン配置の構成を有することを特徴とする。
図6は、本発明の第2の実施の形態の変形例に係る半導体装置の模式的平面パターン構成図を示す。
上記のように、本発明は第1乃至第2の実施の形態によって記載したが、この開示の一部をなす論述及び図面はこの発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなろう。
