发明名称 Extreme Ultraviolet Lithography Process and Mask
摘要 A system of an extreme ultraviolet lithography (EUVL) is disclosed. The system includes a mask having reflective phase-shift-grating-blocks (PhSGBs). The system also includes an illumination to expose the mask to produce a resultant reflected light from the mask. The resultant reflected light contains mainly diffracted lights. The system also has projection optics to collect and direct resultant reflected light to expose a target.

主权项 1. An extreme ultraviolet (EUV) lithography system, comprising: a mask having a plurality of reflective phase-shift-grating-blocks (PhSGBs); an illumination to expose the mask to produce a resultant reflected light reflected from the mask, including from the reflective PhSGBs, wherein the resultant reflected light includes mainly diffracted lights; and optics to collect and direct the resultant reflected light towards a target.
