    Abstract: PROBLEM TO BE SOLVED: To provide an alignment arrangement and an alignment method which reduce influences of change by marks. SOLUTION: The alignment measurement arrangement includes a light source, an optical system and a detector. The light source generates a radiation beam with a plurality of wavelength ranges. The optical system receives the radiation beam, produces an alignment beam, directs the alignment beam to a mark located on an object, receives alignment radiation back from the mark, and transmits the received radiation. The detector receives the alignment radiation, detects an image of the alignment mark and outputs a plurality of alignment signals (r) each associated with one of the wavelength ranges. A processor, in communication with the detector, receives the alignment signals, determines signal qualities of the alignment signals, determines aligned positions of the alignment signals, and calculates a position of the alignment mark based on the signal qualities, aligned positions, and a model relating the aligned position to the range of wavelengths and mark characteristics, including mark depth and mark asymmetry.

    Abstract: PROBLEM TO BE SOLVED: To provide a metrological method capable of measuring particularly CD and overlay among a number of parameters by using a sensor of a type normally used for position measurements in a lithographic apparatus itself.SOLUTION: A pattern includes first and second sub-patterns 312 and 316, mutually adjacently positioned on a substrate, and having a first and a second periodicity respectively. The pattern is observed and a combined signal is obtained, which contains a beat component having a third periodicity at a frequency lower than frequencies of the first and the second periodicity. A measured value of lithographic process performance is obtained by referring to a phase of the beat component. The measurement can be carried out by using an existing alignment sensor of a lithographic apparatus. Sensitivity and accuracy of the measurement can be adjusted by selection of the first and the second periodicity, and therefore the third periodicity.
