MEMS devices are fabricated by a method that involves forming an optical
element (e.g., etalon) over a substrate and then forming a light
modulating element (e.g., interferometric modulator) over the optical
element. In an embodiment, a support structure for the light modulating
element is aligned with the underlying optical element to thereby alter
the appearance of the support structure to a viewer. Such an optical
element is separated from the support structure by one or more buffer
layers.
