Inspection method and apparatus of a glass substrate for imprint
Abstract:
A method for inspecting a glass substrate for imprint including a glass substrate with a pattern surface and a transmissive conductive film coating at least part of the pattern surface, includes an electron beam irradiation step of irradiating the pattern surface of the glass substrate for imprint disposed on a stage with an electron beam having a predetermined irradiation area; an electron detection step of simultaneously detecting electrons from the pattern surface by the electron beam irradiation by means of a detection surface with a plurality of pixels; and a defect detection step of obtaining an image of the pattern surface based on the electrons detected by the detection surface and detecting a defect of the pattern surface.
