Abstract
The making and use of color microlenses in color image sensors and color display devices is described and claimed. The color microlenses combine the function of a colorless microlens and a color filter into a single structure simplifying the fabrication of, and increasing the reliability of display devices and image sensors using the described color microlenses.
Claims24
A method for manufacturing a color microlens array comprising:
- forming a first colored microlens resist layer on a surface, over a plurality of photodetecting regions that will define an image sensing area of an integrated circuit die;
- patterning the first colored microlens resist layer;
- and
- baking the patterned first colored microlens resist layer to cause flowing of the patterned layer resulting in a microlens, with a curved top surface, being formed above each of the plurality of photodetecting regions.
