摘要： MEMS varactors capable of handling large signals and/or achieving a high capacitance tuning range are described. In an exemplary design, a MEMS varactor includes (i) a first bottom plate electrically coupled to a first terminal receiving an input signal, (ii) a second bottom plate electrically coupled to a second terminal receiving a DC voltage, and (iii) a top plate formed over the first and second bottom plates and electrically coupled to a third terminal. The DC voltage causes the top plate to mechanically move and vary the capacitance observed by the input signal. In another exemplary design, a MEMS varactor includes first, second and third plates formed on over one another and electrically coupled to first, second and third terminals, respectively. First and second DC voltages may be applied to the first and third terminals, respectively. An input signal may be passed between the first and second terminals.

摘要： 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.
