Simulation Analysis of Bipolar Amplification in Independent-Gate FinFET and Multi-Channel NWFET Submitted to Heavy-Ion Irradiation
Résumé
The response to heavy-ion irradiation of FinFET and Multi-Channel Nanowire MOSFET (MC-NWFET) operated with independent gates is investigated by 3-D numerical simulation. The bipolar amplification and charge collection of devices with independent gates are particularly investigated and compared to those of conventional devices having a single surrounding gate. We show that the independent-gate operation of both FinFET and MC-NWFET degrades the device immunity to heavy-ion irradiation.
