2015 SHARP Promotion
Why Sharp? [10.3 MB, PDF]
SHARP fills a gap for forward-looking, 2nd- and 3rd-generation EUVL technologies. (1) Extend beyond 0.33-NA (2) Customize the illumination for SMO and the emulation of FlexRay pupils. (3) Recover defect phase and amplitude information. (4) Anamorphic (4x/8x magnification) imaging later in 2015. (5) Image multilayer-coated "wafer masks," and masks created with experimental mask materials that may not be allowed in fabs.
