Abstract

The pseudo MOSFET measurement technique has been a simple and rapid method for characterization of SOI wafers without any device fabrication process. We adopted the pseudo MOSFET technique to examine the surface silicon film thickness dependence of electrical properties of SOI wafer. The measurements showed that turn-on voltage increased and electron mobility decreased as the SOI film thickness was reduced in the SOI film thickness of less than 20 nm region.
