Micromirrors and micromirror arrays described herein are useful, for example in maskless photolithography systems and methods and projection display devices and methods. According to one aspect, the micromirrors comprise a polymer structural layer and a reflective dielectric multilayer for selective reflection and/or redirection of incoming electromagnetic radiation. According to another aspect, incorporation of a reflective dielectric multilayer allows for use of polymer structural materials in micromirrors and prevents damage to such polymer materials due to excessive heating from absorption of electromagnetic radiation, as the reflective dielectric multilayers are highly reflective and minimize heating of the micromirror components. According to yet a further aspect, top down fabrication methods are described herein for making a micromirror comprising a polymer structural layer and a reflective dielectric multilayer.
