Abstract:
The present disclosure generally relates to methods and systems for manufacturing wire grid polarizers (WGP) using Markle-Dyson exposure systems and dual tone development (DTD) frequency doubling. In one embodiment, the method includes depositing a photoresist layer over an aluminum-coated display substrate, patterning the photoresist layer by dual tone development using a Markle-Dyson system to form a photoresist pattern, and transferring the photoresist pattern into the aluminum-coated display substrate to manufacture a WGP having finer pitch, for example less than or equal to about 100 nm, and increased frequency.

Claim (Index 17):
A wire grid polarizer manufacturing method, comprising:\n depositing a photoresist layer over an aluminum-coated display substrate; patterning the photoresist layer by dual tone development using a Markle-Dyson system to form a photoresist pattern, wherein the photoresist pattern includes high light exposure intensity portions, middle light exposure intensity portions, and low light exposure intensity portions, and wherein the dual tone development further comprises:\n removing the high light exposure intensity portions using a first developing solution; and \n removing the low light exposure intensity portions using a second developing solution; \n etching the photoresist pattern into the aluminum-coated display substrate; and removing any remaining photoresist from the aluminum-coated display substrate.
