Image pick-up device having well structure and image pick-up system using the image pick-up device
摘要:
Receiving a subject image at good sensitivity by improving the light collection efficiency of incident light, wherein an image pick-up element includes a light-receiving portion, poly-silicon wiring formed on the light-receiving portion, and a well structure. The poly-silicon wiring is arranged so as to be overlapped with at least a part of the light-receiving portion, and is electrically connected to the light-receiving portion to perform the control of electric charges generated at the light-receiving portion, the switching of the light-receiving portion, and the like. The well structure is formed in at least a part of the area of the light-receiving portion in which the poly-silicon wiring is arranged, and the opened area of the well structure is sufficiently secured.
