ABSTRACT:
A solid state imaging device of the present invention includes a photoelectric convert part, a vertical charge transfer part, a horizontal charge transfer part, an unnecessary charge expelling region. A channel region of the horizontal charge transfer part and the unnecessary charge expelling region have an identical impurity profile. The channel region of the horizontal charge transfer part is applied to a first voltage to be depleted and the unnecessary charge expelling region is applied to a second voltage to be in non-depleted state.
