DEVICE MANUFACTURING INVOLVING STEP-AND-SCAN DELINEATION

摘要

Fabrication of submicron design rule large scale integrated circuits depends upon use of a strut-segmented mask with struts providing mechanical support to permit thinned mask segments consequently yielding improved resolution. "Stitching" - positioning of projected segment images to yield a satisfactory continuous image - is aided by lithographically defined skirts forming a continuous border within strut-supported segments.
