Insight Into Electron Traps and Their Energy Distribution Under Positive Bias Temperature Stress and Hot Carrier Aging
in IEEE Transactions on Electron Devices
| Description | 1. The relation between random telegraph noises (RTN) and NBTI aging has been clarified. It is shown that the increase of RTN by stresses reported in early works is an artefact. 2. A method has been proposed to predict the statistical variations of NBTI for nanometer sized devices. 3. The sources of errors have been identified for hot carrier modelling. 4. A robust kinetic model has been developed and test proven for hot carrier aging. 5. The different types of defects generated under hot carrier stresses have been identified. 6. The interaction between the hot carrier stress and PBTI stress have been clarified. 7. A new method has been developed for direct measurement of RTN-induced threshold voltage shift. |
| Exploitation Route | The industrial partners of the project can use the models developed to simulate their circuits. The TCAD provider can use the model to extract industrial strength model for their simulators. |

| Description | 1. The method developed has been used to model the statistical variation of NBTI. 2. The kinetic model developed has been used to model the hot carrier aging and device lifetime. 3. The method developed for assessing the accuracy of extracted statistical properties has been used to select the number of devices under tests. 4. A prototype of True Random Number Generator has been developed using the generated RTN for IoT security. 5. The PI has been invited to deliver short courses based on the outputs of this project. |
