摘要：
The effect of the Si1-xGex source with an underlying p(+) region on the suppression of the floating body effects in a partially depleted silicon-on-insulator (SOI) metal oxide silicon field effect transistor (MOSFET) is numerically investigated. Compared to a conventional SOI MOSFET, the kink effect and anomalous sub-threshold slope are reduced and the breakdown voltage is substantially increased. The detailed suppression mechanism is also studied. Our results suggest that the narrow bandgap Si1-xGex source and buried p(+) region are favorable to the dispersion of holes generated by impact ionization. (C) 2004 Published by Elsevier B.V.
