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. |

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. |
