Patent ID: 7200506

Claim:
A system for failure analysis, comprising: an apparatus for sample extraction for extracting, as a sample, a part of a substrate by an ion beam process after each of two or more different processes for forming a desired circuit pattern on said substrate, and carrying said sample to a sample storage for storing said sample; an apparatus for filing data of a stored sample for constructing a data base in which at least product name of said substrate, substrate name, and process name are associated with a storage position of said sample; an apparatus for sample storage for storing said sample storage extracted in accordance with the data base of said apparatus for filing data of the sample and selecting said sample corresponding to arbitrary product designation after completion of the product of said sample; an apparatus for performing an additional processing of said sample for taking out said sample selected in response to a failure analysis request and performing an additional process on the basis of additional process information; and an apparatus for failure analysis for analyzing said sample subjected to the additional process.
