Abstract(in English) | Electronic properties of the surface and interface of the SOI wafers as well as the surface of the Si wafers have been characterized by the Kelvin method combined with Surface-Photovoltage (SPV) method. With the use of 340nm UV light source, -0.4[V] of SPV was detected at 1 [mA/cm^2] of the photocurrent density for the 4.5% HF treated p-Si(100) surface. This result indicates that there is anomalously large surface band-bending at the HF-treated p-Si (100) surface. In addition, it is noted that the conductivity type of the p-Si surface region is inverted. On the other hand, very weak SPV with the value of 60[mV] was observed for the HF-treated n-Si(100) surface. These results indicate that the Fermi level position at the surface is pinned in the vicinity of the bottom of the conduction band. Furthermore, the interface recombination rate for the SOI/BOX interface was estimated from the result of the temperature dependence of the contactless I-V characteristics for the SOI wafer. |
