    摘要: A temperature distribution of an object, such as an optical element, onto which radiation energy is irradiated, is measured. The change of the shape of the object is controlled by varying the temperature of a part of the object on the basis of the measured temperature distribution to stabilize the shape of the object. Also, the shape of the object being irradiated is stabilized by causing the same temperature distribution in the object when in the thermally stable condition to be generated in the object while it is being irradiated. If the shapes of masks used to manufacture semiconductor devices are stabilized by using the above methods, highly integrated semiconductor devices can be manufactured.
