Abstract

Synthesis of boron previous termnitridenext term (BN) films are attempted by plasma-assisted chemical vapor deposition using previous termBCl3next term and N2 as source gases. BN films are characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared absorption (FTIR) measurements. Capacitance?voltage (C-V) characteristics are measured for Au/BN/p-Si samples. The dielectric constant is estimated from the capacitance in the accumulation region and the film thickness. A dielectric constant as low as 2.2 is achieved for the BN film. It is found that incorporation of carbon atoms into BN films is effective in reducing the dielectric constant.
