摘要
The effects of substrate vias voltage and deposition temperature on the electrical properties of TiNx/n-Si Schottky diodes were studied. The diodes were fabricated by reactive magnetron sputtering of TiNx films on silicon wafers. As the negative substrate bias voltage increased from -40 to -100 V, the Hooge parameter and effective bulk trap density near the interface first increased and then decreased. The trap characteristics of the diodes were correlated with the stoichiometry of the TiNx measured by ellipsometry.
