Pattern forming apparatus and pattern forming method, movable body drive system and movable body drive method, exposure apparatus and exposure method, and device manufacturing method
Abstract:
A controller of an exposure apparatus is coupled to an alignment system, an aerial image measurement device and an encoder system, to control a drive system based on correction information and measurement information of the encoder system, the correction information compensating a measurement error of the encoder system that occurs due to a plurality of scale members. In an exposure operation of a substrate, a detection operation of a mark of the substrate and a fiducial mark, and a detection operation of an aerial image, the positional information of the stage is measured with the encoder system. In the exposure operation, the substrate is placed facing a lower surface of a nozzle member by a stage, and alignment between a pattern image and the substrate is performed based on detection information of the alignment system and the aerial image measurement device.
