Abstract(in English) | Although the electrical characterization of the top Si layer of the silicon-on-insulator(SOI) structure is very important, the conventional techniques such as DLTS require the electrode formation process. In this paper, we show the Kelvin method combining with the surface-photovoltage(SPV) measurements is capable of determining electrical properties of the surface as well as the near-surface region of the SOI without any device preparation process and completely in a nondestructive way. The measured contact potential difference is very sensitive to the surface condition; the atomic smoothness of the surface becomese, the heigher CPD is measured. Using a metal-coated optical fiber as a probe, we have tried to improve in the spatial resolution. |
