Abstract
A method for preparing a substrate for an exposure process of a lithographic manufacturing method, the method including imposing different local temperatures across the substrate so as to induce different thermal expansion across the substrate before the exposure process. This method is for compensating for deformation of the substrate induced when the substrate is positioned on a substrate table of a lithographic apparatus. There is also provided a local temperature applicator to implement this technique and to a lithographic apparatus including such a local temperature applicator.
