Technical Examples

An image sensor with optical guard rings is provided. The optical guard rings are embedded in a stacked inter-metal dielectric layer between the sensor areas, that is, around each pixel. The refraction index (RI) of the optical guard rings is smaller than that of the stacked inter-metal dielectric layer. Therefore, the incident light with a large angle of incidence is blocked by the optical guard rings and cannot arrive at the adjacent pixels.
