摘要

ArF lithogrpahy which is expected for the next generation optical lithography is adapted for 0.13um design-rule and beyond. ArF Half-Tone Phase Shift Mask(HTPSM) will be applied as1~(st) generation of ArF Lithograph. Also ArF PSM cleaning demands by means of tighter controls related to phase angle, transmittance & contamination on the masks. Phase angle on ArF HT PSM should be controlled within at leat +- 3dg and transmittance controlled within at least +-0.3percent after cleaning process & pelliclization. In the cleaning process of HT PSM, requires not only the remove the particle on mask, but also control to half-tone material for metamorphosis.
