摘要: In a pattern inspection apparatus for comparing images of corresponding areas two patterns, which are formed so as to be identical, judge that non-coincident part the is defect, influence unevenness in brightness patterns caused by difference thickness or like reduced, whereby highly sensitive realized. addition, high-speed can carried out without changing image comparison algorithm. For this purpose, operates perform processing parallel plural areas. Further, convert gradation an signal among compared using different units such that, even case occurs identical images, defect detected correctly.
