Patent ID: 8512585

Claim:
A method of forming an imprint lithography template comprising: providing a substrate layer; disposing a conducting layer on the substrate layer, the conducting layer associated with a first erosion rate; forming a resist layer over the conducting layer; patterning the resist layer; disposing a hard mask layer over at least a portion of the patterned resist layer, the hard mask layer associated with a second erosion rate; forming a planarizing layer having a substantially planar top surface over the hard mask layer and the patterned resist layer; etching the planarizing layer and hard mask layer until the planarizing layer and hard mask layer are substantially removed from unpatterned regions on the conducting layer; removing the resist layer; altering the second erosion rate of the hard mask layer to a third erosion rate while maintaining the first erosion rate of the conducting layer, the third erosion rate less than the second erosion rate; etching, based on the altering, the conducting layer while substantially maintaining the remaining hard mask layer in patterned regions; and, etching the substrate to provide an inverse of the patterned resist layer in the substrate at a standardized pattern depth.
