Abstract:
An exposure apparatus transfers a pattern on a wafer by irradiating a reticle with an illumination light, and the pattern is formed on a pattern surface of the reticle. The exposure apparatus is provided with a reticle stage that moves holding the reticle, and a sensor that irradiates a measurement light on the pattern surface of the reticle held by the reticle stage and detects speckles from the pattern.

Claim (Index 1):
An exposure apparatus that irradiates an energy beam on a mask and transfers a pattern formed on a pattern surface of the mask onto an object, the exposure apparatus comprising:\n a mask stage that moves, holding the mask; a sensor that irradiates a measurement light on the pattern surface of the mask at a first point of time and detects a first information of a first area on the pattern surface, and irradiates the measurement light on the first area and detects a second information of the first area after a predetermined time has passed from the first point of time; and a controller that obtains the first and second information from the sensor and obtains a variation information of the first area, caused by irradiation of the energy beam on the mask, based on the first information of the first area and the second information of the first area that have been detected, wherein the controller calculates a measurement error of the variation information caused by a drift of the sensor.
