Membrane and mask, and exposure apparatus using the mask, and device producing method using the mask

摘要

X-ray or vacuum-ultraviolet-ray transmissive mask membrane is constituted by a laminated film. The laminated film is obtained by continuously forming a SiCN film on one of or each of sides of a SiC film. Thereby, a membrane, which is superior in physical or mechanical strength and in surface conditions and optical transmittance, is provided. Moreover, there is provided a mask using the membrane.
