Interference Lithography Gratings
Interference lithography is an optical nanolithography technology for the fabrication of extensive periodic nanostructures. Critical dimensions of less than 50 nm can be realized. At AMO two interference lithography tools are installed. One setup for extensive, high quality gratings with fixed periods, the other more flexible tool allows quick prototyping. We offer grating fabrication on silicon, silicon dioxide and other substrates with tailored pitch, etch depth and size.
