Abstract
The present invention relates to semiconductor devices with a reduced filter thinning of outer photosites and a method for reducing the thinning of filter layers of the outer photosites. A semiconductor device includes a main surface including a plurality of photosites and bonding pads defined in the main surface, wherein the photosites include inner photosites and outer photosites. The semiconductor device further includes a clear layer deposited over the main surface exclusive of the bonding pads and outer photosites, and a first primary color filter layer deposited over at least first inner photosite and first outer photosite, the first primary color filter transmitting a primary color.
