Abstract: In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.

Abstract: Disclosed is a method of measuring a parameter of a lithographic process, and associated inspection apparatus. The method comprises measuring at least two target structures on a substrate using a plurality of different illumination conditions, the target structures having deliberate overlay biases; to obtain for each target structure an asymmetry measurement representing an overall asymmetry that includes contributions due to (i) the deliberate overlay biases, (ii) an overlay error during forming of the target structure and (iii) any feature asymmetry. A regression analysis is performed on the asymmetry measurement data by fitting a linear regression model to a planar representation of asymmetry measurements for one target structure against asymmetry measurements for another target structure, the linear regression model not necessarily being fitted through an origin of the planar representation. The overlay error can then be determined from a gradient described by the linear regression model.

Abstract: Disclosed are a method, computer program and associated apparatuses for measuring a parameter of a lithographic process. The method comprising the steps of: obtaining first measurements comprising measurements of structural asymmetry relating to a plurality of first structures, each of said plurality of measurements of structural asymmetry corresponding to a different measurement combination of measurement radiation and a value for at least a first parameter; obtaining a plurality of second measurements of target asymmetry relating to a plurality of targets, each of said plurality of measurements of target asymmetry corresponding to one of said different measurement combinations, determining a relationship function describing the relationship between said first measurements and said second measurements, for each of said measurement combinations; determining, from said relationship function, a corrected overlay value, said corrected overlay value being corrected for structural contribution due to structural asymmetry in at least said first structure.

Abstract: An immersion lithography apparatus comprises a temperature controller configured to adjust a temperature of a projection system, a substrate and a liquid towards a common target temperature. Controlling the temperature of these elements and reducing temperature gradients may improve imaging consistency and general lithographic performance. Measures to control the temperature may include controlling the immersion liquid flow rate and liquid temperature, for example, via a feedback circuit.
