Photolithography apparatus and method for handling wafer

Abstract

A method for adhering a reticle onto a top surface of a chuck is provided in accordance with some embodiments of the present disclosure. The method includes sliding a reticle relative to a chuck along a first direction, such that a plurality of fibers over a top surface of the chuck are inclined away from an imaginary line normal to the top surface of the chuck by sliding the reticle relative to the chuck along the first direction; performing a photolithography process using the reticle; and after performing the photolithography process, sliding the reticle relative to the chuck along a second direction opposite to the first direction, such that the fibers are moved back toward the imaginary line by sliding the reticle relative to the chuck along the second direction.

Dependencies are inferred from the claim text.
