Automatic limit dimension measurement method on display manufacturing substrate, display manufacturing large area substrate inspection method, display manufacturing large area substrate inspection device and its operation method
According to an embodiment, a method for automated critical dimension measurement on a substrate for display manufacturing is provided. The method includes scanning a first field of view having a first size with a charged particle beam to obtain a first image having a first resolution of a first portion of the substrate for display manufacturing; determining a pattern within the first image, the pattern having a first position; scanning a second field of view with the charged particle beam to obtain a second image of a second portion of the substrate, the second field of view has a second size smaller than the first size and has a second position provided relative to the first position, the second image has a second.
