Color filter array, imagers and systems having same, and methods of fabrication and use thereof

A processor system, comprising:

• a processor;
• and
• an imager coupled to the processor, the imager comprising;
• a pixel cell array formed in a substrate, the pixel cell array having an array of at least first, second, and third photosensors;
• a color filter array comprising at least first, second, and third color filters corresponding to the first, second, and third photosensors, each of the first, second, and third color filters comprising respective first, second, and third conforming layers formed over first, second, and third base structures, wherein
• the first, second, and third conforming layers are shaped according to colors associated with the corresponding first, second, and third photosensors, and
• peripheral edges of the first, second, and third conforming layers are separated by one of more distances along a lateral plane;
• and
• a microlens array formed over the color filer array.
