Description
それはまず第1に多結晶シリコン抵抗の安定性を得る為である。多結晶シリコンは半導体なので、その上に配線や電極が形成されると、その配線や電極の電位と多結晶シリコン抵抗の電位の相対関係により、多結晶シリコンの内部が空乏化したり蓄積したりする事により抵抗値が変化する。
半導体基板と、
前記半導体基板上に形成した第1の絶縁膜と、
前記第1の絶縁膜上に形成し、低濃度不純物領域と高濃度不純物領域とを有する多結晶シリコンからなる同一形状の複数の抵抗体と、
前記複数の抵抗体上に形成した第2の絶縁膜と、
前記第2の絶縁膜の前記高濃度不純物領域上に形成したコンタクトホールと、
前記コンタクトホールに接続され、かつ前記多結晶シリコンからなる複数の抵抗体を接続する金属配線と、
前記第2の絶縁膜上であって前記抵抗体を1つまたは複数接続してなる複数の抵抗群における前記低濃度不純物領域の上を覆う複数の金属部分とを有し、
前記複数の抵抗群を接続した半導体集積回路において、
前記複数の金属部分の面積が概ね同一であることを特徴とする半導体集積回路とした。
