Patent ID: 7256131

Claim:
A method of patterning a substrate, said method comprising: forming a multi-layered structure on said substrate by positioning on said substrate, a patterned layer having a coating disposed thereon, said patterned layer having a plurality of protrusions and recessions, and forming upon said coating, a planarization layer, with said multi-layered structure having a crown surface facing away from said substrate; and selectively removing portions of said multi-layered structure in superimposition with said protrusions to form a plurality of projections on said substrate with portions of said planarization layer forming a mask in areas of said crown surface in superimposition with said recessions, said projections comprising a first layer having a first width associated therewith and a second layer having a second width associated therewith, said first layer comprising portions of said coating defining a pair of spaced-apart sidewalls and a nadir portion extending therebetween having portions of said planarization layer in superimposition with said nadir portion and positioned between said sidewalls, with said sidewalls defining said first width such that said first width is substantially the same as said second width.
