Abstract:
In a solid state imaging device in whicha plurality of unit pixels each having a sensor unit with a photoelectric conversion region in which a first semiconductor region of a second conductivity-type is formed in a semiconductor region of a first conductivity-type, and on a surface thereof, a high impurity concentration layer of a first conductivity type is formed and an insulating gate transistor for reading out a signal electric charge from said sensing unit, are disposeda solid state imaging device, being characterized in thatsaid photoelectric conversion region of said sensor unit forms a single potential dip for the signal electric charge, anda gate electrode of said insulating gate transistor is formed into a pattern so that its middle portion in a channel width direction is positioned above a central portion of said potential dip or above a vicinity of the central portion of said potential dip.
