    摘要: A SiON overcoat for use on magnetic media for magnetic recording. The SiON overcoat is deposited by pulsed DC sputtering while applying a negative DC bias. The SiON overcoat is especially useful on perpendicular magnetic recording media because of its ability to deposit thinly and evenly on a rough, granular high coercivity recording media while maintaining excellent corrosion protection properties. A SiON overcoat can be applied less than 3 nm thick while still maintaining excellent mechanical and corrosion protection. The overcoat also has a very high density and water contact angle.

    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.
