Patent attributes
A method of forming a lithographic template, the method including, inter alia, creating a multi-layered structure, by forming, on a body, a conducting layer, and forming on the conducting layer, a patterned layer having protrusions and recessions, the recessions exposing portions of the conducting layer; depositing a hard mask material anisotropically on the multi-layered structure covering a top surface of the patterned layer and the portions of the conducting layer; removing the patterned layer by a lift-off process, with the hard mask material remaining on the portions of the conducting layer; positioning a resist pattern on the multi-layered structure to define a region of the multi-layered structure; and selectively removing portions of the multi-layered structure in superimposition with the region using the hard mask material as an etching mask.
