    Abstract: PROBLEM TO BE SOLVED: To improve the compensation of wafer surface topography. SOLUTION: A lithography apparatus includes a substrate table built so that a substrate is held; a projection system constituted so that a radiation beam may be projected on a target part of the substrate through an exposure slit region; a pattern forming device constituted to form a radiation beam pattern formed by giving a pattern in the section of the radiation beam and which focuses the pattern formed radiation beam on the target area of the substrate within a depth of a focus (DOF); and a measuring system constituted so that at least the partial surface topography of the target part is measured. The projection system is configured to form a controlled exposure slit region adjusted so that a surface topography change is equal to or smaller than the depth of the focus on it by adjusting the size of the exposure slit region.
