Abstract:
1. An exposure apparatus that exposes an object with an energy beam and forms a pattern on the object, the apparatus comprising: a first member on which a member subject to transmission/reception of an electric signal is arranged; a second member that is separated from the first member in terms of vibration, the first member and the second member being placed in the exposure apparatus facing each other via a first gap; a signal transmitting device that includes a first section that is mounted on the first member and transmits and/or receives an electromagnetic wave, and a second section that is mounted on the second member so as to correspond to the first section and receives and/or transmits the electromagnetic wave from/to the first section, the first section and the second section respectively include optical fibers that are placed facing each other via a second gap that is substantially the same as or smaller than the first gap; and a drive system that drives the second section at least in a vertical direction so that relative positions of the optical fiber of the first section and the optical fiber of the second section within a facing plane are maintained.
