Multispectral image sensor and method for fabrication of an image sensor
The present invention relates to a multispectral image sensor having a pixel array for detecting images with light components in different wavelength ranges, comprising a plurality of imaging layers each embedded in a semiconductor substrate, wherein in each of the imaging layers an array of photodetecting regions is provided, wherein the photodetecting regions are configured with different absorption characteristics, wherein the imaging layers are stacked so that the photodetecting regions of the arrays are aligned, wherein the absorption characteristics allow a preferred absorption of light components of at least one predetermined wavelength range.
