Table 2. Comparison of Three Major Approaches for the Large-Area Nanofabrication of Metasurfaces.

nanofabrication approach patterning resolution advantages disadvantages refs
DUV photolithography ∼100 nm uniform replication expensive (233 and 237)
compatible with other CMOS fabrication limited to flat and rigid substrate
highly precise alignment hard to control light sources
  need of masks
nanotransfer printing ∼10 nm large-scale fabrication on arbitrary shape need of molds (238, 240, and 241)
cost-effective limited to nanostructures with same heights
enable to continuous replication need of substrates with high thermal resistance (for T-nTP)
diverse materials  
high-n resin NIL ∼10 nm direct process highly dependent on molds (242 and 244)
large-scale fabrication on arbitrary shape hard to align
cost-effective residual resist remains
enable to continuous replication poor durability
high resolution
