Description
・P型半導体基板1A:CP(1A)=1×1017〜1×1019/cm3
・P型エピタキシャル層1B:CP(1B)=1×1011〜1×1016/cm3
・N型半導体領域1C:CN(1C)=1×1012〜1×1017/cm3
・CP(1A)>CN(1C)>CP(1B)
・t(1A)>t(1B)>t(1C)
この形態の固体撮像素子は、図12に示した第3形態に係る固体撮像素子において、入力電極11A,11B,11Cと垂直シフトレジスタの始点側の端部の転送電極との間に、領域R1〜R4を含んで延びたゲート電極12A´を配置したものである。他の構成の構造と作用は、第3形態のものと同一である。各電極の近傍の電子転送方向に沿った縦断面図は、図11に示したものと同一であり、同図のゲート電極12Aを12A´に読み替え、同図の入力電極11Aを入力電極11A,11B,11Cとして読み替えたものである。各電流源13A,13B,13Cから入力電極11A,11B,11Cに供給される電子は、ゲート電極12´への印加電圧を制御することによって、対応する垂直シフトレジスタへの注入量を制御することができる。
上述のゲート電極12Aを備えたタイプの実施形態(例:第4形態)において、上記凹部DPを備えないこととして、表面入射型の固体撮像素子とした場合、モニタ用チャネルD1とダミーチャネルD2〜D4の形成された領域R1、R2における、ゲート電極12A、転送電極3A,3B上には、アルミニウム膜などからなる遮光膜SFが配置されている。なお、遮光膜SFは、転送電極3A,3Bとは絶縁されている。この構造の場合、表面側から入射した光は遮光膜SFによって遮断され、モニタ用チャネルD1とダミーチャネルD2〜D4に入射することはない。したがって、高精度の増倍率モニタが可能となる。
