Abstract
An image sensor includes charge accumulation region of first conductivity type, floating diffusion of the first conductivity type, stacked semiconductor region having first region of second conductivity type arranged below the charge accumulation region, second region of the second conductivity type arranged above the first region, and third region of the second conductivity type arranged above the second region. The sensor further includes fourth region of the second conductivity type arranged in region between the charge accumulation region and the floating diffusion, below the floating diffusion, and above the stacked semiconductor region, transfer gate for transferring charges of the charge accumulation region to the floating diffusion, and fifth region of the second conductivity type arranged in region below the charge accumulation region and the fourth region, and above the stacked semiconductor region.
