The invention relates to a CIS device and a manufacturing method thereof. The CIS device comprises a stacked substrate structure, the stacked substrate structure comprises a first pixel substrate and a second pixel substrate which are bonded with each other in the vertical direction, and at least one visible light pixel unit and at least one infrared light pixel unit are distributed on the stacked substrate structure in a non-overlapping mode in the transverse direction.
