摘要： An apparatus includes an optical system configured to irradiate a surface of a substrate with a beam, a control unit configured to control a position of the irradiation of the beam, and a first measurement unit and a second measurement unit each configured to measure a position of a mark formed on the substrate. The second measurement unit is placed at a position closer to an optical axis of the optical system than the first measurement unit is. Based on a position measurement value measured by the first measurement unit and position measurement values measured at different timings by the second measurement unit, the control unit controls the position of the beam irradiated to the substrate. The position measurement values measured at the different timings are values obtained from the same mark or values obtained from two marks adjacent to a common shot area.

摘要： A method of manufacturing a semiconductor device by using an exposure apparatus having a reticle stage and a projection optical system includes a first period in which substrates are exposed by using a first reticle arranged on the reticle stage, a second period in which substrates are exposed by using a second reticle arranged on the reticle stage, and a third period which is between the first and second periods. The method includes changing, in at least part of the third period, the first reticle arranged on the reticle stage to the second reticle, and performing control, in the first and second periods, to adjust temperature distribution of an optical element of the projection optical system so as to reduce change in aberration of the projection optical system. The third period is shorter than the first period.
