Abstract:
1. A method of forming a microlens comprising the steps of: providing a wafer having a first planarization layer formed on the wafer, color filters formed over the first planarization layer, and a second planarization layer formed on the color filters in a first region, the wafer having an indentation formed therein in a second region; forming a layer of a filler material over the second planarization layer in the first region and over the wafer in the second region, thereby substantially filling the indentation with the filler material; removing a portion of the filler material such that the filler material in the indentation remains; forming a microlens material over the second planarization layer; removing a portion of the microlens material; substantially removing the filler material; and forming the microlens from the remaining microlens material.
