Abstract
One of the objects of the present invention is to provide a semiconductor measurement apparatus capable of obtaining a measurement result that appropriately reflects the deformation of a pattern even if plural causes for the deformation of the pattern exist together. In order to attain the above object, the semiconductor measurement apparatus is proposed in the following way. The semiconductor measurement apparatus is capable of measuring the dimensions between plural measurement points of different positions of the edge of a reference pattern and plural corresponding points of the circuit pattern of an electronic device, in which the corresponding points correspond to the plural measurement points. In addition, the semiconductor measurement apparatus is capable of measuring the spacings between the circuit pattern and the reference pattern, both of which exist in a predefined measurement area, selecting a second measured value aggregation from a first measured value aggregation comprised of measured values at plural points in the measurement area based on a predefined sampling condition, and calculating the measurement value based on the second measured value aggregation.
