Abstract

See full text

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.
