OBLIQUE VACUUM DEPOSITION FOR ROLL-ROLL COATING OF WIRE GRID POLARIZER LINES ORIENTED IN A DOWN-WEB DIRECTION

摘要

Material may be obliquely deposited on a plurality of down-web oriented features on a substrate oriented in a down-web (z) direction or other than a cross-web (y) direction. A linear source generates a vapor flux of a material oriented parallel to the substrate and either parallel to the y direction or at an angle intermediate the y and z directions. The vapor flux impinges on the substrate at an oblique angle relative to the y direction. The substrate moves in the z direction relative to the linear source as the material impinges on the substrate. The vapor flux has a sufficiently narrow angular distribution in a plane perpendicular to the substrate and parallel to the y direction that material deposits on predetermined portions of the down-web oriented features but not other portions, forming parallel down-web oriented lines of the material on the substrate.
