Abstract This study introduces an approach, termed film‐based multi‐photon lithography (MPL), for the efficient fabrication of electromagnetic surface structures. Unlike conventional MPL, which utilizes droplet‐shaped photosensitive volumes 3D structures, this method employs thin films to minimize influence axial voxel dimensions. modification enables rapid printing 2D structures over large areas with dry objective lenses, achieving feature sizes as small 250 nm. The versatility MPL is demonstrated through terahertz metasurfaces featuring metallized split‐ring resonators on glass substrates, well mid‐infrared comprising dielectric pillars silicon‐on‐insulator substrates.
