Abstract
The present invention provides a lithography system including an obtaining unit which obtains a transfer function describing a relationship between first vibration generated in one lithography apparatus of two lithography apparatuses among at least three lithography apparatuses, and second vibration generated in the other lithography apparatus upon transmission of the first vibration to the other lithography apparatus, and a calculator which calculates, based on the transfer function, an amount of vibration of a first lithography apparatus among the at least three lithography apparatuses due to vibration of lithography apparatuses, other than the first lithography apparatus, and a controller which controls the lithography apparatuses other than the first lithography apparatus, so that the amount of vibration calculated falls below a tolerance.
