摘要: A shape measurement apparatus includes a work stage supporting target substrate, pattern-projecting section including light source, grating part partially transmitting and blocking generated by the source to generate image projecting lens making on of an image-capturing capturing reflected control controlling stage, section, calculating reliability index phases image, which is corresponding target, inspecting using phases. Thus, accuracy may be enhanced.
