Abstract
A wire grid polarizer and method of making a wire grid polarizer can protect delicate wires of the wire grid polarizer from damage. The wire grid polarizer can include a protective-layer located on an array of wires. The array of wires can further be protected by a chemical coating on an inside surface of the air-filled channels, closed ends of the air-filled channels, damaged wires of the array of wires in a line parallel to an edge of the wire grid polarizer, or combinations thereof. The method can include (i) providing the wire grid polarizer, (ii) applying the protective-layer, by physical vapor deposition or chemical vapor deposition but excluding atomic layer deposition, onto the array of wires, (iii) cutting the wire grid polarizer wafer into multiple wire grid polarizer parts, then (iv) protecting the array of wires.
