    Abstract: An exposure method is described, the method comprising the steps of a) transferring a first pattern onto each of a plurality of target portions of a substrate, the first pattern including at least one alignment mark; b) measuring a position of a plurality of alignment marks and determining an alignment mark displacement (dx, dy) for each of the plurality of alignment marks as a difference between a respective predetermined nominal position of the alignment mark and the respective measured position of the alignment mark; c) fitting a mathematical model to the plurality of alignment mark displacements to obtain a fitted mathematical model, d) determining a position of the first pattern in each of the plurality of target portions, based on the fitted mathematical model; e) transferring a second pattern onto each of the plurality of target portions, using the determined position of the first pattern in each of the plurality of target portions, wherein the mathematical model comprises polynomials Z1 and Z2: Z1 = r 2 cos(2 θ ) Z2 = r 2 sin(2 θ ) in polar coordinates (r, θ) or Z1 = x 2 - y Z 2= xy in Cartesian coordinates (x, y).

    Abstract: A lithographic projection apparatus may include a laser cleaning device. The laser cleaning device is constructed and arranged to clean a surface. The laser cleaning device includes a laser source constructed and arranged to generate radiation, and an optical element constructed and arranged to focus the radiation in a focal point in order to generate a cleaning plasma in a background gas above the surface. The laser cleaning device is further provided with a gas supply constructed and arranged to generate a jet of protection gas at a location near the plasma.
