Abstract
Various embodiments of the present disclosure are directed towards a semiconductor structure including a first substrate comprising a first semiconductor material. A first light sensor is disposed within the first substrate. The first light sensor is configured to absorb electromagnetic radiation within a first wavelength range. A second light sensor is disposed within an absorption structure underlying the first substrate. The second light sensor is configured to absorb electromagnetic radiation within a second wavelength range different from the first wavelength range. The absorption structure underlies the first light sensor and comprises a second semiconductor material different from the first semiconductor material.
