Abstract: An image sensor that includes a first layer and a second layer bonded to the first layer. The first layer includes a first substrate including a first front surface and a first back surface, a floating diffusion region formed in the first substrate, a first pad, and a first conductive line provided between the floating diffusion region and the first pad. The second layer includes a second substrate including a second front surface and a second back surface, pixel transistors formed on the second substrate, a second pad, and a second conductive line provided between one of the pixel transistors and the second pad. The second conductive line passes through the second substrate and is electrically connected to a lower portion of the pixel transistor.
