After completion of an arbitrary device process, an apparatus for micro-sample extraction extracts a part of a wafer as a micro-sample of a size equal to or larger than a repetition pattern with a probe and places the extracted micro-sample to a micro-sample storage, and the micro-sample storage is stored into an apparatus for micro-sample storage. The wafer is subjected to a post process and an observation desired position is determined in response to a failure analysis requirement. After that, the micro-sample is unloaded from the micro-sample storage by an apparatus for additional processing of the micro-sample and is placed onto an observation sample holder. By performing an additional process in the observation desired position, a failure analysis sample is prepared, and analysis information obtained by an apparatus for failure analysis is output.
