Abstract:
The present disclosure is directed to a method for reducing the surface deformation of a color filter after a baking process in an image sensor device. Surface deformation can be reduced by increasing the surface area of the color filter prior to baking. For example, forming a grid structure over a semiconductor layer of an image sensor device, where the grid structure includes a first region with one or more cells having a common sidewall; disposing one or more color filters in a second region of the grid structure; recessing the common sidewall in the first region of the grid structure to form a group of cells with the recessed common sidewall; and disposing another color filter in the group of cells.

Claim (Index 13):
A method, comprising:\n forming a grid structure comprising cells over a semiconductor layer, wherein the ce comprise sidewalls with a sidewall height; masking a region of the grid structure to form a masked region and an unmasked region in the grid structure, wherein the masking prevents etching the sidewalls of the cells in the masked region; and etching the sidewalls of the cells in the unmasked region of the grid structure to reduce the sidewall height compared to the sidewall height of the cells in the masked region.
