摘要： A lithographic system includes a lithographic apparatus comprising a projection system which projects a patterned radiation beam onto a target portion of a substrate and an alignment system which measures the position of a feature of the pattern on the substrate at a number of locations over the substrate. A controller compares the measured positions with points on a grid of values and extrapolates values for intermediate positions on the substrate based on values of corresponding intermediate points on the grid, so as to provide an indication of the intermediate positions on the substrate and their displacements relative to the grid. The grid is based on at least one orthogonal basis function, the measurement on the substrate being performed at positions corresponding to the root values of the at least one orthogonal basis function.

摘要： A lithographic apparatus includes an illumination system configured to condition a radiation beam, a support for a patterning device, a substrate table for a substrate, a projection system, and a control system. The patterning device is capable of imparting the radiation beam with a pattern in its cross-section to form a patterned radiation beam. The projection system is configured to project the patterned radiation beam as an image onto a target portion of the substrate along a scan path. The scan path is defined by a trajectory in a scanning direction of an exposure field of the lithographic apparatus. The control system is coupled to the support, the substrate table and the projection system for controlling an action of the support, the substrate table and the projection system, respectively. The control system is configured to correct a local distortion of the image in a region along the scan path by a temporal adjustment of the image in that region.

摘要： A method of selecting a grid model for correcting a process recipe for grid deformations in a lithographic apparatus is disclosed. First a set of grid models is provided. Subsequently, alignment data are obtained by performing an alignment measurement on a plurality of alignment marks on a number of substrates. For each grid model it is checked whether the alignment data is suitable to solve the grid model. If so, the grid model is added to a subset of grid models. The grid model with lowest residuals is selected. In addition to alignment data, metrology data may be obtained by performing an overlay measurement on a plurality of overlay marks on the number of substrates. For each grid model of the subset simulated metrology data may then be determined that is used to determine overlay performance indicators. The grid model is then selected using the overlay performance indicators.
