Charge Collection Analysis under Heavy Ion Irradiation in Multiple-Gate Devices: FinFETs and Nanowires
Résumé
We investigate Single-Event Transients (SET) in various designs of multiple-gate devices: FinFETs and nanowires. Heavy ion experimental results are explained by using a thorough charge collection analysis of fast transients measured on dedicated test structures. Multi-level simulations are performed to get new insights into the charge collection mechanisms in multiple-gate devices. Implications for multiple-gate device design hardening are finally discussed.
