Abstract

The electrical characteristics of ultrathin-body SOI CMOSFETs are intensively investigated. It is demonstrated that electron mobility increases as SOI thickness decreases, when SOI thickness, TSOI, is in the range from 3.5 nm to 4.5 nm. On the other hand, hole mobility decreases monotonically as TSOI decreases. In addition, it is demonstrated that, when SOI thickness is thinner than 4 nm, slight (even atomic-level) SOI thickness fluctuations have a significant impact on threshold voltage, gate-channel capacitance, and carrier mobility of ultrathin-body CMOSFETs.
