Temperature Dependence of Digital SET Pulse Width in Bulk and SOI Technologies

Using three-dimensional mixed-mode simulation, temperature dependence of digital SET pulse width in bulk and PD SOI inverter chains has been studied. It was found that temperature has a very important impact on digital SET. Using a LET of 60 MeVmiddotcm² /mg, when temperature rises from -55 to 125^degC , the digital SET pulse width in bulk and floating SOI inverter chains rises remarkably, while in a SOI inverter chain with ideal body tie, the digital SET pulse width is almost constant with rising temperature. Detailed analysis showed that pulse broadening with rising temperature is primarily due to enhancement of bipolar amplification.
