X-ray mask, method for fabricating the same, and pattern formation method
摘要:
A method for forming an X-ray exposure mask having an X-ray permeable film with a high visible-light transmissivity. The method includes the steps of forming an aluminum oxide anti-reflective film on an x-ray permeable film, placing an x-ray absorber on the anti-reflective film and etching with the x-ray absorber to form x-ray pattern.
