| 摘要 |
The present invention provides a method to pattern a substrate which features creating a multi-layered structure by forming, on the substrate, a patterned layer having protrusions and recessions. Formed upon the patterned layer is a conformal layer, with the multi-layered structure having a crown surface facing away from the substrate. Portions of the multi-layered structure are removed to expose regions of the substrate in superimposition with the protrusions, while forming a hard mask in areas of the crown surface in superimposition with the recessions.
