Abstract
Disclosed are apparatus and methods for fabricating a static interferometric display device. A plurality of sputtering modules is used to form static interferometric elements on a substrate. These elements each have a plurality of interferometric sub-elements that each has an interferometric stack. A first sub-element of each element is formed so that an interferometric modulation of light due to the first element's stack transmits at a first color, and a second sub-element of each element is formed so that a second color is transmitted. The sub-elements of each element are arranged with respect to each other so that all of the elements appear as a third color to a user if all the sub-elements of each element are left unmasked. A printing system is then used to mask one or more sub-elements of one or more elements so as to form, with the elements, a static image having multiple colors.
