Description
実施の形態1にかかる半導体集積回路装置の構造について、自己分離型の高耐圧集積回路装置(HVIC)を例に図1,2,7〜9を参照しながら説明する。図1は、実施の形態1にかかる高耐圧集積回路装置の平面構造を示す図である。図2は、図1の切断線A−A'および切断線C−C'における断面構造を示す断面図である。実施の形態1にかかるHVIC50は、図10に示す電力変換装置を構成するHVICに対応する駆動素子であり、ハーフブリッジ回路のIGBT(トランジスタ)114,115のオン・オフを制御する機能を有する。HVIC50の接続構成(電力変換装置の回路構成)、HVIC50のレベルシフト機能(レベルシフト回路)の回路構成、および、HVIC50によるIGBT114,115の駆動方法は例えば従来と同様でよいため、説明を省略する(図10〜12の説明を参照)。
次に、実施の形態2にかかる半導体集積回路装置(HVIC)の構造について説明する。図4は、実施の形態2にかかる高耐圧集積回路装置の要部の構造を示す断面図である。図5は、実施の形態2にかかる高耐圧集積回路装置の別の一例の要部の構造を示す断面図である。実施の形態2にかかるHVICが実施の形態1にかかるHVICと異なる点は、n-型ウエル領域4に接するようにp-型分離領域53が配置されている点である。具体的には、図4(a)のように、n型ウエル領域3とn-型ウエル領域4との間に、n型ウエル領域3およびn-型ウエル領域4に接するようにp-型分離領域53を配置してもよい。また、p-型分離領域53の代わりに図4(b)のように、n型ウエル領域3とn-型ウエル領域4とが接しないように形成してp型半導体基板1が表面に露出する構成とすることでp型分離領域153を形成してもよい。また、図5のように、基板おもて面からn-型ウエル領域4を貫通してp型半導体基板1の残部に達するようにp-型分離領域53を形成し、内周側および外周側に配置されたn-型ウエル領域4同士に挟まれるようにp-型分離領域53を配置してもよい。
次に、実施の形態3にかかる半導体集積回路装置(HVIC)の構造について説明する。図6は、実施の形態3にかかる高耐圧集積回路装置の要部の構造を示す断面図である。実施の形態3にかかるHVIC60が実施の形態1にかかるHVICと異なる点は、耐圧領域であるn-型ウエル領域4内を接合分離するようにp-型分離領域(分離領域)63が配置されている点である。具体的には、p-型分離領域63は、セット側およびリセット側のnチャネルMOSFET211と、Vs電位領域81およびH−VDD電位領域82とを接合分離する。以下に、p-型分離領域63の平面レイアウトについて、p型ウエル領域5に接して環状をなす略U字状の3つのp-型分離領域63(以下、第1〜3p-型分離領域63a〜63cとする)を配置した場合を例に説明する。
次に、実施の形態4にかかる半導体集積回路装置(HVIC)の構造について説明する。図7は、実施の形態4にかかる高耐圧集積回路装置の要部の構造を示す断面図である。図8は、図7の切断線B−B'における断面構造を示す断面図である。実施の形態4にかかるHVIC70が実施の形態1にかかるHVICと異なる点は、n型ウエル領域3内を接合分離するp-型分離領域に代えて、誘電体領域(分離領域)73によってn型ウエル領域3内を誘電体分離している点である。誘電体領域73は、例えばn型ウエル領域3の深さよりも深いトレンチ71の内部に例えば酸化膜(SiO2)などの一般的な誘電材料膜72を埋め込んでなる。
次に、実施の形態5にかかる半導体集積回路装置(HVIC)の構造について説明する。実施の形態5にかかるHVICが実施の形態1にかかるHVICと異なる点は、高電位領域、低電位領域およびHVJTを構成するn型領域(図1のn型ウエル領域3およびn-型ウエル領域2,4)に代えて、p型半導体基板1上にn型エピタキシャル成長層を積層してなるエピタキシャル基板(半導体チップ)や、p-型エピタキシャル層と埋め込みn+型半導体層からなる埋め込みエピタキシャル基板を用いてHVICを構成している点である。この場合、p型ウエル領域5は、n型エピタキシャル成長層を貫通して下層のp型半導体層(p型半導体基板1やp-型エピタキシャル層)に達する深さで設ければよい。
