a method for manufacturing grating reference materials having a self-traceability includes: acquiring a mask substrate including a window region and a non-window region; fabricating, a self-traceability mask on the mask substrate by using a laser-focused atomic deposition technique; acquiring a photoresist sample including an extreme ultraviolet photoresist and a second substrate; exposing the extreme ultraviolet photoresist by combining the self-traceability mask with the soft x-ray interference lithography, and then performing a development process after exposing to obtain a photoresist grating structure; and transferring the photoresist grating structure to the second substrate to obtain the grating reference materials.
