  • Patent number: 11527390
    Abstract: Cathode structures are disclosed for use with pulsed cathodic arc deposition systems for forming diamond-like carbon (DLC) films on devices, such as on the sliders of hard disk drives. In illustrative examples, a base layer composed of an electrically- and thermally-conducting material is provided between the ceramic substrate of the cathode and a graphitic paint outer coating, where the base layer is a silver-filled coating that adheres to the ceramic rod and the graphitic paint. The base layer is provided, in some examples, to achieve and maintain a relatively low resistance (and hence a relatively high conductivity) within the cathode structure during pulsed arc deposition to avoid issues that can result from a loss of conductivity within the graphitic paint over time as deposition proceeds. Examples of suitable base material compounds are described herein where, e.g., the base layer can withstand temperatures of 1700° F. (927° C.).

The target information may be used to manage operation of the sputtering system. Managing operation of the sputtering system may include setting an adjustable parameter of a deposition process or deciding when to replace a sputtering target. Machine learning may be used to apply the time of flight camera data in managing the sputtering system operation.
