Abstract:
The wire grid polarizer (WGP) comprises an array of parallel, elongated nanostructures located over a surface of a transparent substrate and a plurality of spaces, including a space between adjacent nanostructures. Each of the nanostructures can include (1) a plurality of parallel, elongated wires located on the substrate, including an inner-pair located between an outer-pair; (2) lateral-gaps between each wire of the outer-pair and an adjacent wire of the inner-pair; (3) and a center-gap between the two wires of the inner-pair.

Claim (Index 3):
A method of making a wire grid polarizer (WGP), the method comprising the following steps:\n providing an array of parallel, elongated support ribs located over a transparent substrate and spaces between the support ribs, the spaces being solid-material-free; conformal coating the substrate and the support ribs with a first-layer while maintaining solid-material-free at least a portion of the spaces between the support ribs; etching the first-layer to remove horizontal segments and leaving an array of inner-pairs of parallel, elongated wires along sides of the support ribs, each wire of each inner-pair being separate from the other wire of the inner-pair; conformal coating the substrate and the support ribs with a second-layer while maintaining solid-material-free at least a portion of the spaces between the support ribs; etching the second-layer to remove horizontal segments and leaving middle-pairs, the middle-pairs being an array of parallel, elongated wires, each wire of each middle-pair being separated from the other wire of the middle-pair by wires of the inner-pair; conformal coating the substrate and the support ribs with a third-layer while maintaining solid-material-free at least a portion of the spaces between the support ribs; etching the third-layer to remove horizontal segments and leaving outer-pairs, the outer-pairs being an array of parallel, elongated wires along sides of the support ribs, each wire of each outer-pair being: spaced apart with respect to the other wire of the outer-pair; and spaced apart with respect to wires of the inner-pair by wires of a middle-pair, the wires of the middle-pair being formed of material of the second-layer; and etching the support ribs and the middle-pair to form: lateral-solid-material-free-regions between at least a portion of each wire of each outer-pair and at least a portion of an adjacent wire of the inner-pair; and center-solid-material-free-regions between at least a portion of the two wires of each inner-pair.
