Abstract
The interface charged defects in amorphous silicon oxynitride (SiOxNy) films deposited on (111) Si have been investigated. The films were deposited by low-pressure chemical vapor deposition (LPCVD) at a temperature of 860°C and at a pressure of 400 mTorr, using a mixture of SiCl2H2-NH3-N2O. The study was based on the analysis of capacitance-voltage (C-V) characteristics taken at different test signal frequencies. The presence of different types of interface traps explains the observed strong frequency dispersion of the C-V curves. The observed densities of the charged defects are attributed to nitrogen incorporation at the SiOXNY/Si interface, which leads to suppression of defects generation.
