Abstract
A device includes a first integrated circuit containing a photodiode and a first metal interconnect structure connected to the photodiode, and a second integrated circuit containing a transistor and a second metal interconnect structure connected to the transistor. The first integrated circuit and the second integrated circuit are connected together through the first metal interconnect structure and the second metal interconnect structure. Since no transistor is present around the photodiode, the photodiode has an increased photosensitive area and an improved fill factor, resulting in an increase of the quantum efficiency, higher integration and lower consumption of the image sensor.
