Abstract:
A method for making a wire grid polarizer (WGP) can provide WGPs with high temperature resistance, robust wires, oxidation resistance, and corrosion protection. In one embodiment, the method can comprise: (a) providing an array of wires on a bottom protection layer; (b) applying a top protection layer on the wires, spanning channels between wires; then (c) applying an upper barrier-layer on the top protection layer and into the channels through permeable junctions in the top protection layer. In a variation of this embodiment, the method can further comprise applying a lower barrier-layer before applying the top protection layer. In another variation, the bottom protection layer and the top protection layer can include aluminum oxide. In another embodiment, the method can comprise applying on the WGP an amino phosphonate then a hydrophobic chemical.

Claim (Index 1):
A method of manufacturing a wire grid polarizer (WGP), comprising the following steps in the following order:\n providing an array of wires on a bottom protection layer with channels between adjacent wires, the channels being air filled, the bottom protection layer including aluminum oxide; applying a lower barrier-layer on the wires and on the bottom protection layer inside of the channels in a conformal layer, the lower barrier-layer including a metal oxide; applying by sputter deposition a top protection layer, including aluminum oxide, at a distal end of the wires, farthest from the bottom protection layer, such that the top protection layer: spans the channels, keeping the channels air filled; forms a continuous layer with the top protection layer on adjacent wires touching; and has permeable junctions, including a permeable junction between the top protection layer on adjacent wires; then applying an upper barrier-layer including a hydrophobic chemical: through the permeable junctions into the channels and onto surfaces of the channels; and on an outermost surface of the top protection layer.
