Abstract:
1. A system for failure analysis, comprising: a sample extraction apparatus for extracting, as a sample, a minimum repetition pattern of a repetition pattern formed on a semiconductor wafer by an ion beam process after an arbitrary process is performed to the semiconductor wafer; a data storing apparatus for storing data of the extracted sample, the wafer and additional process information for performing an additional process to the extracted sample; micro-sample storages for storing the extracted sample prior to the additional processing; a storage apparatus for storing the micro-sample storages prior to the additional processing and selecting a micro-sample storage on the basis of additional process information in response to a request; an apparatus for performing the additional process to the extracted sample stored in the selected micro-sample storage on the basis of additional process information and in response to the request; and an apparatus for failure analysis for analyzing the extracted sample that has been subjected to the additional process.
