发明名称 Pattern shape inspection method and apparatus thereof
摘要 This invention relates to a pattern shape inspection method and an apparatus thereof for conducting a first step of irradiating wideband illuminating light which contains far ultraviolet light to a sample from a perpendicular direction, inspecting a shape of the pattern based on a spectral waveform of reflecting light detected from the sample, and detecting an edge roughness of the pattern based on the spectral waveform of the reflecting light detected from the sample, and a second step of irradiating a laser beam to the sample from an oblique direction, and detecting the edge roughness of the pattern based on scattered light detected from the sample.
