Abstract
A method of forming a base for a color filter layer of an image sensor is disclosed. The image sensor includes an array of pixels formed in a substrate. The method comprises depositing a polymer layer over the substrate. The polymer layer is patterned to form gaps in the polymer layer, the gaps located between the pixels. Finally, a second polymer layer is deposited into the gaps.
