Method of manufacturing an X-ray exposure mask and device for controlling the internal stress of thin films

摘要

An X-ray mask can be manufactured by forming an X-ray transmitting thin film (12) on a mask support (11), forming an X-ray absorber thin film (14) on the X-ray transmitting thin film (12), and patterning the X-ray absorber thin film (14) with a desired pattern to form an X-ray absorber pattern. Prior to the pattern­ing, at least one inert element with an atomic number greater than that of neon is ion-implanted in the X-ray absorber thin film (14).
