More Information
Summary:A device for an image sensor is provided. The device includes a semiconductor device comprising a photo-sensitive region and a metallization stack for electrically contacting the photo-sensitive region. The photo-sensitive region is configured to generate an electric signal based on incident light. Further, the device includes an optical stack formed on a surface of the semiconductor device for guiding the incident light towards the photo-sensitive region. The optical stack comprises a plurality of regions stacked on top of each other. The plurality of regions comprise a filter region configured to selectively transmit the incident light only in a target wavelength range.
