    摘要: A scatterometer, configured to measure a property of a substrate, includes a radiation source which produces a radiation spot on a target formed on the surface of the substrate, the size of the radiation spot being smaller than the target in one direction along the target, the position of the radiation spot being moved along the surface in a series of discrete steps. A detector detects a spectrum of the radiation beam reflected from the target and produces measurement signals representative of the spectrum corresponding to each position of the radiation spot. A processor processes the measurement signals produced by the detector corresponding to each position of the radiation spot and derives a single value for the property.
