Patent ID: 7907197

Claim:
A solid-state imaging device comprising: an imaging portion including a plurality of light receiving portions disposed in a matrix of rows and columns, and a vertical transfer register, disposed in each column of the matrix, for transferring electric charges transferred from the light receiving portions in a vertical direction; a horizontal transfer portion for transferring electric charges transferred from the vertical transfer registers in a horizontal direction; an output part for outputting an electrical signal converted from electric charges transferred from the horizontal transfer portion; wherein the imaging portion, the horizontal transfer portion and the output part are formed in a first conductivity type semiconductor substrate having a second conductivity type region, and a predetermined reference potential is applied to the second conductivity type semiconductor region; first reference potential applying means for applying a reference potential to the second conductivity type semiconductor region corresponding to an area where the output part is formed; and second reference potential applying means for applying a reference potential to the second conductivity type semiconductor region corresponding to an area where the imaging portion is formed.
