Reticle protection member, reticle carrying device, exposure device and method for carrying reticle

Abstract

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.
