Optoelectronic device arranged as a multi-spectral light sensor having a photodiode array with aligned light blocking layers and N-well regions

An optoelectronic device, comprising:

• a photodiode array including a plurality of first photodiodes, each first photodiode including a respective n+ region and a respective n-well region, each n-well region having an upper surface;
• a guide array disposed over the photodiode array, the guide array including a plurality of guide members separated from one another by a layer of light-blocking material, the plurality of guide members being disposed over the n+ regions of the plurality of first photodiodes, such that each guide member is disposed over a different respective n+ region, and the layer of light-blocking material being disposed over and substantially covering an entirety of the upper surfaces of the n-well regions of the plurality of first photodiodes;
• and
• a filter array disposed over the guide array, the filter array including a plurality of bandpass filters, each bandpass filter being aligned with a different one of the plurality of guide members, each bandpass filter having a different transmission band.
