Abstract
A pixel circuit includes a floating diffusion layer of a first conductivity-type between a drain/source of a second conductivity-type and a source/drain of the second conductivity-type. The source/drain and the drain/source touch the floating diffusion layer. A cathode of a photoelectric converter is electrically connected to the floating diffusion layer. An anode of the photoelectric converter touches the cathode. The cathode is of the first conductivity-type and the anode is of the second conductivity-type.
Claims19
A pixel circuit comprising:
- a first floating diffusion layer of a first conductivity-type between a first drain/source of a second conductivity-type and a first source/drain of the second conductivity-type, said first source/drain and said first drain/source touching said first floating diffusion layer;
- a photoelectric converter including a cathode and an anode, the anode touching the cathode, the cathode being electrically connected to said first floating diffusion layer, said cathode being of said first conductivity-type, said anode being of said second conductivity-type;
- a second floating diffusion layer of the first conductivity type electrically connected to said cathode;
- and
- a first layer of the second conductivity-type between said first floating diffusion layer and said second floating diffusion layer.
