Abstract
Embodiments of the disclosure provide methods and system for inspecting and treating a substrate. In one embodiment, a method is provided including transmitting a first plurality of beams from a diffractive beam splitter to a first surface of a substrate to generate a reflection of a second plurality of beams, wherein the first plurality of beams are spaced apart from each other upon arriving at the first surface of the substrate; receiving the second plurality of beams on a recording surface of an optical device, wherein the second plurality of beams are spaced apart from each other upon arriving at the recording surface; measuring positional information of the second plurality of beams on the recording surface; comparing the positional information of the second plurality of beams to positional information stored in a memory; and storing a result of the comparison in the memory.
