초록

The structural characterization of cubic boron nitride (c-BN) thin films was performed using a B4C target in a radio-frequencymagnetron sputtering system. The deposition processing conditions, including the substrate bias voltage, substratetemperature, and base pressure were varied. Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopywere used to analyze the crystal structures and chemical binding energy of the films. For the BN film deposited at roomtemperature, c-BN was formed in the substrate bias voltage range of −400 V to −600 V. Less c-BN fraction was observed asthe deposition temperature increased, and more c-BN fraction was observed as the base pressure increased.
