  • Abstract
    This work examines a novel approach based on a well known process in CMOS technology. A combined deep-UV interference lithography, contact printing, and Damascene metalization were used to realize wiregrid micropolarizers for use with CMOS/CCD cameras as well as infrared focal plane arrays. The Damascene process was utilized to avoid some of the difficulties in patterning high-aspect ratio metal grids.
