Abstract

Diamond-like thin films having high uniformity and high crystallinity are produced by introducing a hydrocarbon material gas into a chamber, ionizing the gas, and depositing the ionized gas on a substrate. The gas is ionized by thermionic emission from two or more files of hot cathodes, each file having a plurality of filaments arranged at substantially uniform intervals in a linear or zigzag line configuration. Each file of hot cathodes is surrounded separately by an anode at a substantially uniform distance from a respective file of the filaments.
