摘要： A method of fabricating a master stamper/imprinter for manufacturing a patterned recording medium by nano-imprint lithography comprises steps of: (a) providing a substrate having a surface; (b) forming a layer of a hybrid resist material on the surface, the resist layer having an exposed upper surface; (c) subjecting selected areas of the exposed upper surface of the resist layer to an energy beam to form therein a latent image of a topographical pattern to be formed in the resist layer and having a correspondence to a pattern to be formed in a patterned recording medium; and (d) developing the latent image into the topographical pattern in the resist layer, wherein only those areas of the resist layer which have received an energy beam exposure dose between a positive-tone threshold dose D0p and a negative-tone threshold dose D0n are developed.

摘要： A method of imprint lithography includes imprinting a first pattern with a first template on a first substrate of a lithographic template. A second pattern is imprinted with a second template on the substrate of the lithographic template. The first pattern and the second pattern at least partially overlap, thus forming a third pattern. The third pattern is lithographically formed on a second substrate with the lithographic template. In an embodiment, the first pattern is a concentric line pattern formed by thin film deposition. In an embodiment, the second pattern is a radial line pattern. In an embodiment the first pattern and the second pattern may have line frequency increased.
