Abstract:
1. A stress measuring device comprising: an electron beam irradiating unit that irradiates a specimen with an electron beam, a spectroscopy unit, operatively configured in association with the electron beam irradiating unit, that is configured to analyze light generated primarily by the electron beam irradiated from the electron beam irradiating unit, and hitting the specimen so as to obtain a spectrum, and a stress calculating unit, operatively configured in association with the spectroscopy unit and the electron beam irradiating unit, that is configured to calculate, from the spectrum of the specimen obtained when the specimen is being irradiated primarily with the electron beam from the electron beam irradiating unit, a stress change generated in the specimen based on a spectrum shift between the spectrum of the generated light obtained when the specimen is in a predetermined state and the spectrum of the generated light obtained when the specimen is in a state different from the predetermined state.
