A compact, low-height prototype of a six-axis precise positioning stage for microfabrication h a s been developed. X and Y stage positioning requires nanometer positioning resolution and robustness against atmospheric turbulence. The stiffness and dead play of the traveling mechanism were improved by using rolling contact guides, and the positioning resolution was improved by using a iriction drive mechanism. Anaiog signais from a n opticai h e a r scaie are influenced little by atmospheric turbulence. Using these advantages of the optical linear scale and with a newlv develoDed Dositioning algorithm. one-nanometer resolution was obtained.
