Periodic nanostructures fabricated by Talbot extreme ultraviolet lithography

A table top nanofabrication system which combines the classic Talbot imaging effect and a compact table top soft-x ray laser is described in this paper. Periodic nanostructures on millimeter square are fabricated using this robust, simple and defect tolerant fabrication method. Talbot lithography allows for a complete coherent extreme ultraviolet lithography process in a compact table top system. Double exposure allowed for the reduction of the feature sizes.
