摘要:
A position measurement device measures the position of a position measurement mark formed on the lower surface of a reticle, thereby measuring the position of the reticle. A position measurement device measures the position of the position measurement mark formed on the lower surface of a lower lid, thereby measuring the position of the lower lid. The relative displacement of the reticle and lower lid is known when the position of the reticle and the position of the lower lid are known. Therefore, when the lower lid having the reticle loaded thereon is carried with a carrying device and set in an exposure device, the stop position of the lower lid is determined by taking this displacement into account. As a result, the reticle can be correctly set in the exposure device.

A position measurement device 29 measures the position of a position measurement mark 26 formed on the lower surface of a reticle 1, thereby measuring the position of the reticle 1. A position measurement device 30 measures the position of the position measurement mark 27 formed on the lower surface of a lower lid 2b, thereby measuring the position of the lower lid 2b. The relative displacement of the reticle 1 and lower lid 2b is known when the position of the reticle 1 and the position of the lower lid 2b are known. Therefore, when the lower lid 2b having the reticle 1 loaded thereon is carried with a carrying device and set in an exposure device, the stop position of the lower lid 2b is determined by taking this displacement into account. As a result, the reticle 1 can be correctly set in the exposure device.

The present invention relates to a substrate transporting method that transports substrates such as wafers or reticles, a substrate transport apparatus, and an exposure apparatus for use in lithography of, for example, semiconductor integrated circuits, and it is an object of the present invention to efficiently heat a substrate. Furthermore, a substrate transporting method that, after transporting a substrate disposed in the ambient atmosphere into a vacuum chamber and drawing a vacuum therein, transports the substrate to a stage apparatus disposed in a vacuum atmosphere, comprises the step of: transporting the substrate, which is disposed in the ambient atmosphere, to the stage apparatus in a state wherein the substrate is held by a holding means, which can regulate the temperature of the substrate.
