Abstract
A CMOS image sensor includes an active pixel structure suitable for sensing light incident from outside and converting a sensed light into an electrical signal, and an optical block structure suitable for blocking a visible light and passing a UV light to check and evaluate an electrical characteristic of the active pixel area. The UV pass filter includes first and second insulation layers comprising an insulator, and a metal layer formed between the first and second insulation layers.
