Patent ID: 7261831

Claim:
A method of patterning a substrate, said method comprising: creating a multi-layered structure by forming, on said substrate, a patterned layer from a material having a polymerizable compound and a surfactant having a surface energy that is less than a surface energy of said polymerizable compound, with said patterned layer having protrusions and recessions, and forming, upon said patterned layer, a conformal layer, with said multi-layered structure having a crown surface facing away from said substrate, said patterned layer having a first thickness in superimposition with said recessions and having a second thickness, differing from said first thickness, in superimposition with said protrusions, with said first and second thicknesses being greater than zero; and selectively removing portions of said multi-layered structure to expose regions of said substrate in superimposition with said protrusions while forming a hard mask in areas of said crown surface in superimposition with said recessions.
