This method enables simultaneous ion-assisted deposition on both sides of a vertically suspended substrate at a grounded electrical potential with one rf generator. In the positively self-biased electrode system, the cathode sheath is located close to the grounded electrode. Accordingly, positive ions are accelerated toward the grounded electrode, producing an ion-assisted reaction on the surface of the substrate. The grounded substrate is advantageous when transporting a substrate holder suspended vertically in an in-line multilayer deposition system. An important feature of this electrode is the electrical capacitance between the hollow anode chamber and the ground which is parallel to the sheath capacitance. Application of the electrode to the deposition process of thin film magnetic recording disks in pure methane gas was investigated. Diamond-like carbon (DLC) films were deposited at a rate of 3 nm/s on the magnetic layer, with uniform film thickness within ±5% over a substrate measuring 95 mm in diameter. Analysis of this film showed that its characteristics are essentially the same as those of DLC film deposited by the conventional method using a cathode sheath on a high-voltage electrode.
