The precision working station is a typical mechanism in manufacturing equipment for VLSI
its accuracy being doubtlessly of significance. Based on the equipment in the authors'laboratory
a dynamic testing system for errors of precision working station is developed
inwhich frequency-division
phase-fitting
and error-calculation are carried out by an 8098 microcontroller
and hence the data collection and the data processing are integrated.The system is flexible and easy to use with a larger range of phase-fitting and a higher measuring accuracy.
