ABSTRACT:
Micromechanical devices are formed on a substrate using a sacrificial layer deep X-ray lithography process to produce a rotating microrotor which is driven magnetically. The rotor typically has a diameter of a few hundred microns or less and is formed as a free structure which is assembled onto a hub formed on a substrate. Stator pole pieces are formed on the substrate of a ferromagnetic material surrounding the rotor, and are al
