Abstract:
1. A pattern measuring device for selecting pattern information by referring to a library having stored pattern information created based on charged particles emitted from a specimen and information regarding pattern shapes with a relationship established therebetween, comprising: a processing section for referring, with respect to waveform information obtained based on radiation of a charged particle beam onto a specimen, to a library having stored a plurality of pattern information pieces formed based on simulation under different process conditions and information regarding a plurality of pattern information with a relationship established therebetween, and for thereby selecting information regarding a pattern shape stored in the library, wherein the processing section is arranged to obtain a first relationship between a change of the process conditions and a change of the pattern information in accordance with waveform information to be obtained by the radiation of the charged particle beam onto the specimen, and to obtain a second relationship between the first relationship and a change of the pattern information and the process conditions to be obtained by a simulation.
