  • This paper reports the measurement and analysis of the short channel effects and the punchthrough voltage of SOI-MOSFET with a self-aligned ground plane electrode in the silicon mechanical substrate underneath the buried oxide. When the channel length is reduced below 0.2${\mu}{\textrm}{m}$ it is observed that the threshold voltage roll-off and the subthreshold swing with channel length are reduced and DIBL is improved more significantly in GP-SOI devices than FD-SOI devices. It is also observed from the dependence of threshold voltage with substrate biases that the body factor is a higher in GP-SOI devices than FD-SOI devices. From the measurement results of punchthrough voltage, GP-SOI devices show the higher punchthrough voltages than FD-SOI devices
