Abstract:
1. A solid-state imaging apparatus comprising: a plurality of unit pixels arranged in a vertical direction and a horizontal direction in a two-dimensional matrix form; and, within said unit pixels, photoelectric converting means for accumulating a signal charge according to an amount of light received; a floating diffusion portion for extracting the signal charge obtained by said photoelectric converting means; an amplifying transistor for extracting a potential variation by the signal charge of said floating diffusion portion; a reading transistor for transferring the signal charge accumulated by said photoelectric converting means to the floating diffusion portion on the basis of a line selection signal; and a reading selection transistor for controlling said reading transistor on the basis of a pixel selection signal; wherein gate potential of at least one of said reading transistor and said reading selection transistor which is on a side of said photoelectric converting means is set to a negative potential with respect to a well region.
