Abstract:
A lithography system is provided. The lithography system includes a mask and an optical module. The optical module is configured to optically form an invisible pellicle over the mask to protect the mask from contaminant particles. As a solid pellicle used in the prior arts is omitted, the critical dimension (CD) error from the boarder effect due to reflection of some light by the solid pellicle and the exposure radiation energy consumption caused by the solid pellicle can be avoided

Claim (Index 20):
The method as claimed in  claim 16 , wherein the step of generating a plurality of light beams toward a direction of gravity by the illumination sources to illuminate a space over a surface of the mask comprises:\n generating a plurality of light beams with a first light intensity by the illumination sources to illuminate the space over the surface of the mask before a lithography exposing process; and generating a plurality of light beams with a second light intensity by the illumination sources to illuminate the space over the surface of the mask during the lithography exposing process, wherein the first light intensity is greater than the second light intensity.
