Abstract
Official abstract text for this publication.
A solid-state imaging device is capable of simplifying the pixel structure to reduce the pixel size and capable of suppressing the variation in the characteristics between the pixels when a plurality of output systems is provided. A unit cell ( 30 ) includes two pixels ( 31 ) and ( 32 ). Upper and lower photoelectric converters ( 33 ) and ( 34 ), transfer transistors ( 35 ) and ( 36 ) connected to the upper and lower photoelectric converters, respectively, a reset transistor ( 37 ), and an amplifying transistor ( 38 ) form the two pixels ( 31 ) and ( 32 ). A full-face signal line 39 is connected to the respective drains of the reset transistor ( 37 ) and the amplifying transistor ( 38 ). Controlling the full-face signal line ( 39 ), along with transfer signal lines ( 42 ) and ( 43 ) and a reset signal line ( 41 ), to read out signals realizes the simplification of the wiring in the pixel, the reduction of the pixel size, and so on.
First claim
Opening claim text (preview).
What is claimed is: 1. A solid-state imaging device comprising: an imaging area having a plurality of unit cells arranged in a two-dimensional array, each unit cell including: a plurality of pixels; a plurality of photoelectric converters, each photoelectric converter of the plurality of photoelectric converters corresponding to one of the plurality of pixels; an amplifying transistor, shared by at least two pixels of the plurality of pixels, that amplifies a signal read out…
