| Outline of Final Research Achievements |
It was developed a deposition system for DLC films by using a pseudo-spark discharge plasma CVD method. The XPS spectrum indicated C1s peak that are typical of amorphous carbon.
The abundance ratio of sp3 bonding in the film and film hardness increased with rising of the substrate voltage. The maximum hardness was calculated to be 5.8 GPa at the substrate voltage of -300 V. By inserting the floating electrode between the electrodes, the ion density slightly decreased, and the plasma wasn’t ejected continuously. Hydrogen ICP was added to the system and its characteristics were investigated. At RF power of 300 W, the ion density at 200 mm downstream from coil was of the order of 1012 cm-3. Furthermore, it was confirmed that the phase difference between current and voltage changes with respect to RF power (50~300 W).
