Abstract:
1. A method of analyzing a crystalline state on a surface of a specimen, comprising the steps of: irradiating said specimen with an ion beam; measuring secondary electrons generated by irradiation of said ion beam; repeating said irradiating step and said measuring step with each variation in an angle of incidence of said ion beam with respect to said specimen; and determining said crystalline state based on the variation in amount of said secondary electrons corresponding to the variation of said angle of incidence; wherein said crystalline state is a crystallographic orientation of each of crystal grains, and said crystallographic orientation is determined based on a difference between the angle of incidence of said ion beam corresponding to maximum measured amount of said secondary electrons and the angle of incidence of said ion beam corresponding to minimum measured amount of said secondary electrons.
