Abstract
A pattern measurement method and measurement apparatus are provided that appropriately evaluate the deformation of a pattern occurring due to a micro loading effect. In order to achieve the above-mentioned object, there are provided pattern measurement method and apparatus that measure a dimension of a pattern formed on a sample. In the pattern measurement method and apparatus, distances between a reference pattern and a plurality of adjacent patterns adjacent to the reference pattern or inner diameters of the reference pattern in a plurality of directions are measured, and the measurement results of the plurality of distances between the reference pattern and the adjacent patterns or the measurement results of the inner diameters of the reference pattern in the plurality of directions are classified according to distances between the reference pattern and the adjacent patterns or directions of the patterns adjacent to the reference pattern.
