Micromechanics is an emerging field with many applications in microsen
sors and microactuators. The processing too which is needed for these
devices must produce three-dimensional structures from many materials
with submicron tolerances. Synchrotron based X-ray lithography can be
used to fabricate photoresist molds with structural heights to 500 mum
and nearly perfect edge acuity. The plastic molds can be converted to
metal molds via electroplating. Fabricated metal parts can be assembl
ed to form complex structures. An example of this technique is a fully
functional planar, magnetic micromotor which has been fabricated and
is in the testing phase.
