Claim Text:
1. A lithography system including at least three lithography apparatuses each that form a pattern onto a substrate held by a substrate stage, the system comprising: a calculation unit that calculates, based on a transfer function, a vibration of a first lithography apparatus, among the at least three lithography apparatuses, due to vibrations of lithography apparatuses other than the first lithography apparatus, among the at least three lithography apparatuses; and a control unit that controls the lithography apparatuses other than the first lithography apparatus, so that the vibration of the first lithography apparatus calculated by the calculation unit falls below a tolerance, wherein the transfer function is a relationship between a first vibration generated in one of two lithography apparatuses, among the at least three lithography apparatuses, and a second vibration generated in the other of the two lithography apparatuses, upon transmission of the first vibration to the other lithography apparatus.
