Based on the theory of suface plasmon resonance and the special nano-optical effect of metal-dielectric composite, we study super-resolution photolithography using multilayer films. The main point is to use 365 nm exposal light to realize super-resolution imaging by using a mask with a period of 230 nm and linewidth of 100 nm. We discuss the selection of the parameters multi-film with equal thickness, and achieve a sufficient contrast and high intensity through numerical simulation, then verify the obtained results by the plasmon nanolithography technique. Choosing the best scheme, we achieve large-area super-resolution images with the subwavelength structure.
