IPC: G03F7/20
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent generation of heat by an actuator of a vibration absorbing device because of constant interference acting upon the vibration absorbing device. SOLUTION: A vibration absorbing system 11 for controlling vibration of a stepper body 40 drives and controls actuators 7A-7D and 32A-32C according to output from a displacement sensor 10 and a vibration absorbing substrate 11 and controls vibration of vibration absorbing table.
