发明名称 EUVL mask, method of fabricating the EUVL mask, and wafer exposure method using the EUVL mask
摘要 A mask for extreme ultra violet lithography (EUVL) and a method of fabricating the same, and a wafer exposure method using the same. According to a method of fabricating the mask, a light reflective layer pattern is formed on a transparent substrate to reflect extreme ultraviolet light. The extreme ultraviolet light is incident to and transmitted by the transparent substrate. A light absorption layer on the transparent substrate is formed to fill between the light reflective layer patterns and absorb the extreme ultraviolet light.
