Abstract
An image sensor includes pixels arranged parallel to an upper surface of a substrate and a pixel isolation film disposed between the pixels. Each pixel includes a floating diffusion region doped with impurities of a first conductivity type, a transfer gate structure adjacent to the floating diffusion region, and a transistor. The transfer gate structure includes a transfer gate electrode layer, a transfer gate insulating layer, and a transfer gate spacer adjacent to the transfer gate insulating layer in a first direction parallel to the upper surface of the substrate, and a portion of the transfer gate spacer is disposed between the floating diffusion region and the transfer gate electrode layer. In each pixel, a floating diffusion contact connected to the floating diffusion region is disposed more adjacent in the first direction to the pixel isolation film than to the transfer gate structure.
