WebMetasurfaces comprise sub-wavelength nanostructures. By the design and arrangement of the constituent nanostructures, metasurfaces are able to impart customized polarization, amplitude and phase to incident light. Additionally, metasurfaces can be lithographically mass-produced, enabling miniature and multifunctional metasurface optical elements. In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. T…
