Abstract:
1. A solid state image pickup device, comprising: a pixel array unit having a plurality of pixels in a two-dimensional matrix that includes a plurality of pixel columns, wherein each pixel includes a photoelectric converting element, and wherein each pixel is included in one of the pixel columns; a plurality of signal processing circuits each operable to process a respective signal output from each of the plurality of pixels, wherein at least one signal processing circuit is provided for each of the pixel columns, wherein each signal processing circuit includes at least one of a correlated double sampling circuit and an analog/digital converter circuit, the at least one of the correlated double sampling circuit and the analog/digital converter circuit each including at least a first and a second capacitor structure, each of the first and the second capacitor structures being one of a trench and a stacked structure, the stacked structure including: the trench structure including: wherein only the low resistance layer, the storage electrode, and the insulating film completely fill the trench, and the storage electrode, the low resistance layer and the insulating film between them form a three-dimensional trench capacitor; wherein the first capacitor structure is electrically connected to the second capacitor structure; and wherein each of the capacitor structures includes a plurality of small capacitor structures that are arranged in a capacitor column, each of the plurality of small capacitor structures having the same capacitance.
