An interferometric modulator is formed by a stationary layer and a mirror
facing the stationary layer. The mirror is movable between the undriven
and driven positions. Landing pads, bumps or spring clips are formed on
at least one of the stationary layer and the mirror. The landing pads,
bumps or spring clips can prevent the stationary layer and the mirror
from contacting each other when the mirror is in the driven position. The
spring clips exert force on the mirror toward the undriven position when
the mirror is in the driven position and in contact with the spring
clips.
