Abstract: An improved cathodic arc source and method of DLC film deposition with a carbon containing directional-jet plasma flow produced inside of cylindrical graphite cavity with depth of the cavity approximately equal to the cathode diameter. The generated carbon plasma expands through the orifice into ambient vacuum resulting in plasma flow strong self-constriction. The method represents a repetitive process that includes two steps: the described above plasma generation/deposition step that alternates with a recovery step. This step provides periodical removal of excessive amount of carbon accumulated on the cavity wall by motion of the cathode rod inside of the cavity in direction of the orifice. The cathode rod protrudes above the orifice, and moves back to the initial cathode tip position. The said steps periodically can be reproduced until the film with target thickness is deposited. Technical advantages include the film hardness, density, and transparency improvement, high reproducibility, long duration operation, and particulate reduction.

Abstract: A thin film of material on a substrate is formed in a continuous process of a physical vapor deposition system, in which material is deposited during a variable temperature growth stage having a first phase conducted below a temperature of about 500° C., and material is continuously deposited as the temperature changes for the second phase to above about 800° C.

Abstract: An improved cathodic arc source and method of DLC film deposition with a carbon containing directional-jet plasma flow produced inside of cylindrical graphite cavity with depth s of the cavity approximately equal to the cathode diameter. The generated carbon plasma expands through the orifice into ambient vacuum resulting in plasma flow strong self-constriction. The method represents a repetitive process that includes two steps: the described above plasma generation/ deposition step that alternates with a recovery step. This step provides periodical removal of excessive amount of carbon accumulated on the cavity wall by motion of l o the cathode rod inside of the cavity in direction of the orifice. The cathode rod protrudes above the orifice, and moves back to the initial cathode tip position. The said steps periodically can be reproduced until the film with target thickness is deposited. Technical advantages include the film hardness, density, and transparency improvement, high reproducibility, long duration operation, and particulate reduction.
