Abstract:
1. A method of patterning on a substrate comprising the steps of: (a) providing an apparatus consisting essentially of: an ultraviolet light source; a micromirror positioned to redirect light from the light source toward the substrate; a prism set between the micromirror and the substrate; a lens that reflects the light onto the substrate; a reaction chamber disposed about the substrate; one or more chemical lines connected to the reaction chamber; one or more chemicals connected to the chemical lines; and a computer connected to, and controlling, the micromirror and the supply of the one or more reaction chemicals to the reaction chamber via the chemical lines; (b) generating a light beam from the ultraviolet light source; (c) illuminating the micromirror with the light beam; (d) redirecting the light beam with the micromirror onto the substrate; and (e) catalyzing a light sensitive reaction at a site where light strikes the substrate within the reaction chamber using the redirected light beam in a predetermined pattern, wherein the light beam passes through the prism set after illuminating the micromirror.
