Abstract:
1. A method of forming a lithographic template, said method comprising: creating a multi-layered structure, by (i) forming, on a body, a conducting layer, and (ii) forming on said conducting layer, a patterned layer having protrusions and recessions, said recessions exposing portions of said conducting layer; depositing a hard mask material on said multi-layered structure, said deposited hard mask material covering a top surface of said patterned layer and said portions of said conducting layer; removing said patterned layer, with said hard mask material remaining on said portions of said conducting layer; positioning a resist pattern on said multi-layered structure to define a region of said multi-layered structure; and selectively removing portions of said multi-layered structure in superimposition with said region using said hard mask material as an etching mask, wherein selectively removing said portions of said multi-layered structure using said hard mask material as an etching mask comprises removing portions of said conducting layer and said body in a single step.
