Abstract
An image sensor is provided. The image sensor includes a red (R) pixel, a green (G) pixel, a blue (B) pixel and an infrared (IR) pixel, and R, G and B filters respectively disposed at the R, G and B pixels. The image sensor also includes an IR pass filter disposed at the IR pixel and an IR filter stacked with the R, G and B filters, wherein the IR filter cuts off at least IR light with a specific wavelength. Furthermore, a method of forming an image sensor is also provided.
