Cryocharacterization of CMOS devices
Paul Stampfer
11:15 - 12:15 Wednesday 08 January 2020 PH 01 150

This master thesis is part of the PIEDMONS project, that aims at the development of miniaturized and portable ion traps. Such ion traps have many possible application (quantum computing, GPS-free positioning, ion clocks to name a few) and the traps are most likely operated at cryogenic temperatures. In order to integrate electronic circuitry needed to operate the ion trap into the cryogenic regime, models that accurately describe the behavior of electronic devices at such low temperatures need to be provided.
I will present measurements of semiconductor devices of a 130 nanometer CMOS technology. These devices will be used to build electronic circuitry that operates at cryogenic temperatures.
Additionally, I will discuss effects altering the characteristics of a MOSFET at low temperatures.
A Python model was written, that considers several of these effects. I will show how this model works and discuss its limitations.
