Abstract
A method of preparing a metal mask substrate includes providing a metal substrate. Next, a gloss is measured and obtained from the surface of the metal substrate. Next, the gloss is determined whether to be within a predetermined range. When the gloss is determined within the predetermined range, a photolithography process is performed to the metal substrate, where the predetermined range is between 90 GU and 400 GU.
