摘要: The invention provides a photo mask with an electric discharge (ESD) protective function. The photo mask has a transparent substrate comprising quartz or glass, a patterned shielding layer located in the predetermined area of the surface of the transparent substrate, and an ESD protective layer positioned on the surface of the transparent substrate and surrounding the shielding layer. The ESD protective layer comprises a plurality of discharging peaks. The peaks aid in a neutralizing discharge reaction, which discharges harmful static electricity into the air.
