20080198248Reduced edge effect from recesses in imagers - Methods for making a recessed color filter array for a semiconductor imager employing a sidewall spacer for reducing an edge effect from the array are disclosed. In one embodiment, a substrate is provided having an upper surface. Then, a recess is formed into the upper surface of the substrate. The recess has a bottom and a sidewall. Subsequently, a sidewall spacer is formed on the sidewall of the recess. A color resist is deposited into the recess after forming the sidewall spacer. In the embodiment, the sidewall spacer is formed of a material having a surface energy lower than that of a material defining the bottom of the recess. The color resist, when deposited into the recess, adheres less to the sidewall than to the bottom of the recess. Thus, the color resist does not conform to a shape of an edge portion of the recess where the sidewall and the bottom meet, thereby reducing the edge effect.08-21-2008
