Lithography fabrication
WebFabrication of an entire layer often entails processing the wafer through lithography before it undergoes subsequent operations in other modules such as etch, implant, etc. The steps in the semiconductor lithographic process are outlined in Fig. 11.1 and illustrated in Fig. 11.2 for a negative and a positive resist. Web13 apr. 2024 · Metasurfaces are composed of periodic sub-wavelength nanostructures and exhibit optical properties that are not found in nature. They have been widely investigated for optical applications such as holograms, wavefront shaping, and structural color printing, however, electron-beam lithography is not suitable to produce large-area metasurfaces …
