摘要： A method of forming a layer of a hard, abrasion, and corrosion-resistant hydrogenated carbon (C:H) material on a substrate surface comprises steps of: (a) providing a vacuum chamber including a carbon sputtering target in the interior space thereof; (b) providing a substrate in the chamber interior space, a surface of the substrate the sputtering target; (c) supplying the vacuum chamber with at least one hydrocarbon gas and at least one inert gas at separately controllable flow rates and applying a sufficient negative potential to the carbon target to generate a plasma in said interior space to deposit a layer of the C:H material on the substrate surface by a process comprising simultaneous sputtering of the carbon sputtering target and plasma enhanced chemical vapor deposition (PECVD) of carbon and hydrogen from the hydrocarbon gas, wherein: step (c) includes separately controlling the flow rates of each of the hydrocarbon and inert gases such that the amount of C atoms in the C:H which are contributed by the PECVD component of the process is less than about 50 at. %. Embodiments of the invention include utilizing the C:H material as a protective overcoat layer for magnetic and magneto-optical recording media.

摘要： Sputtering method for producing amorphous hydrogenated carbon thin films with high sp.sup.3 content. By sputtering the carbon with a pulsed DC power supply having high voltage peaks, a carbon film with remarkably high sp.sup.3 bonding fraction can be obtained. Previously, carbon films with a very high sp.sup.3 fraction film with content as high (e.g. as 80%) could only be produced by methods such as filtered cathodic arc deposition or chemical vapor deposition methods (CVD) such as plasma-enhanced chemical vapor deposition (PE-CVD) and ion-beam deposition operating at some narrowly defined range of deposition conditions. It is very advantageous to use sputtering to create a high sp.sup.3 content film, since sputtering is more manufacturable and has higher productivity compared to CVD or ion-beam deposition methods. The resultant carbon film has excellent durability and corrosion resistance capability down to very low thickness. Also compared to PE-CVD and ion-beam deposition, the new sputtering process produce much less particles and the process can be run on a manufacturing tool for much longer time, thereby increasing the productivity of the machine, and providing disks with higher quality.
