Abstract
The present invention relates to a highly functional imaging device that can be manufactured through a small number of steps. The imaging device is formed in such a manner that a first stacked body in which a plurality of devices are stacked and a second stacked body in which a plurality of devices are stacked are bonded to each other. For example, a pixel circuit, a driver circuit of a pixel, and the like can be provided in the first stacked body, and a reading circuit of the pixel circuit, a memory circuit, a driver circuit of the memory circuit, and the like can be provided in the second stacked body. With these structures, the imaging device which is small can be formed. Furthermore, wiring delay or the like can be prevented by stacking circuits, so that high-speed operation can be performed.
