摘要: The present application describes a method and a device for keeping the mask dimensions of a mask (6) constant in the mask plane in lithography. The mask (6) is heated due to the exposure during lithography. By means of thermal and/or mechanical methods, the dimensions of the mask (6) are kept constant. It is possible to use additional methods or devices, e.g. an air cooler (17) or an air heater (17), in order to prevent a change in the mask dimensions in the mask plane.
