Abstract
This work reports on the physical and electrical characterization of the oxide/semiconductor interface in MOS capacitors with the SiO2 layer deposited by a high temperature process from dichlorosilane and nitrogen-based vapor precursors and subjected to a post deposition annealing process in N2O. Low interface state density (Dit ≈ 9.0×1011cm-2eV-1) was found at 0.2 eV from EC, which is comparable to the values typically obtained in other lower temperature deposited oxides (e.g., TEOS). A barrier height of 2.8 eV was derived from the Fowler-Nordheim plot, very close to the ideal value expected for SiO2/4H-SiC interface. Basing on these preliminary results, the integration in MOSFETs devices can be envisaged.
