Abstract
An anomalous output voltage overshoot observed during the turn-off of single short-channel thin-film silicon-on-insulator SOI n-MOSFETs is reported. The parasitic floating-base bipolar device, triggered by impact ionization, is shown to be responsible for this effect. Because switching occurs over a subnanosecond time scale, the charge dynamics related to the bipolar action are essential to explain this voltage overshoot.<>
