Abstract:
A method of making a wire grid visible light polarizer and infrared reflector comprising the steps of:directing a first electromagnetic interference pattern comprising a series of parallel fringes spaced no more than 100 nm apart onto a substrate surface to preferentially heat selected portions of the substrate surface according to the first interference pattern; selectively depositing a first conductive material on the substrate surface according to the first interference pattern by exposing the substrate to the first conductive material in the gas phase, the first material capable of preferentially accumulating as a function of surface temperature; directing a second electromagnetic interference pattern comprising a grid pattern having spacings of no less than 200 nm onto a substrate surface to preferentially heat selected portions of the substrate surface according to the second interference pattern; and selectively depositing a second conductive material on the substrate surface according to the second interference pattern by exposing the substrate to the second conductive material in the gas phase, the second material capable of preferentially accumulating as a function of surface temperature.
