PIXEL, PIXEL FORMING METHOD, IMAGING DEVICE AND IMAGING FORMING METHOD

摘要

A pixel is provided with a photodiode region which includes a photoelectric conversion portion for receiving light and generating electrons, and a charge storage portion for storing electric charge. The pixel is configured in such a manner that an electron exclusion region is provided in the photodiode region with the diameter of a circle having the maximum diameter among circles that can exist in the surface of a region through which electrons can pass in the photodiode region as the width of an electron passage region in the photodiode region, and the width of the electron passage region is smaller than when the electron exclusion region is not provided.
