Abstract(in English) | Ultra-thin body (UTB) SOI MOSFET is one of the most promising structures for future VLSIs because of its high short channel effect immunity. Mobility in UTB pMOSFETs in conventional (100) substrate has been experimentally investigated, and severe mobility degradation has been observed as tsor is reduced below 5nm. In this study, hole mobility in (110)-oriented UTB pMOSFETs is investigated. It is shown that the mobility, which is much higher than that in the universal curve in conventional (100)-oriented pMOSFET, is not degraded until tsor is thinned to 3nm. The high mobility in the UTB regime in (110) pMOSFET is attributed to subband modulation by carrier confinement and heavier hole effective mass normal to channel surface. |
