Abstract
Imager devices are formed with light block material between microlenses to enhance the characteristics of image acquisition. The light block material may be deposited over the lenses, and then partially removed to expose central portions of the lenses. The invention is applicable to, among other things, imager devices having pixel arrays formed with the light block material and integrated with one or more processing components in a semiconductor device.
