Abstract

In this work the electrical conduction and breakdown properties of thermal oxides grown on phosphorus-doped polysilicon have been investigated by using ramped I-V measurements. The oxide films, grown from phosphorus-doped polysilicon deposited at 560\ulcorner, have higher breakdown field(6.8MV/cm) and lower leakage current than those deposited at 625\ulcorner. Also the effective energy barrier height(\ulcorner)calculated from the Fowler-Nordheim curve of polyoxide was 0.76eV for 560\ulcorner deposited film and 0.64eV for 625\ulcorner deposited film.
