An analytical model for proton-induced single-event upset cross-sections in SRAMs is presented using parameters extracted from heavy-ion data. Measurements on a 12-nm FinFET SRAM and literature data validate the model across technologies.

Presenting author: Solomon Tolson

An empirical model for terrestrial neutron failure-in-time (FIT) rates as a function of threshold LET value is presented for multiple bulk FinFET technologies. Results show that all flip-flop (FF) designs lie on the same curve.

Presenting author: David Lucsanyi

Improved G4SEE simulation capabilities have been integrated into the fifth generation of FLUKA, and demonstrated by simulations of intermediate-energy neutrons, obtaining particle-by-particle distributions of range, energy deposition, LET and their evolution in silicon.

1. Northwest Institute of Nuclear Technology, China

Presenting author: Wen Zhao

An improved ion track temporal characteristics model was developed and incorporated into single-event effects TCAD simulation. The impact of ion track temporal characteristics on SEE responses of devices operating at different switching speeds was analyzed.

Presenting author: Jean-Luc AUTRAN

A general framework for the diffusion-collection model is proposed to analytically determine time-dependent equations of the collected current and charge. The effects of carrier recombination and carrier drift under a constant electric field are included.

Presenting author: Cyril Ardisson

A drift-diffusion solver extended with displacement damage mechanisms is validated against p-i-n diode measurements. Simulations reproduce the forward voltage shift under neutron irradiation and demonstrate that partial volume irradiation missestimates local displacement damage dose.

This work proposes a deep learning based SET prediction method for SiGe HBTs. A dual-branch LSTM network prediction model is designed. The prediction accuracy of the model is validated using TCAD and heavy-ion experimental data.

SEU characteristics in a 28-nm SRAM-based FPGA were investigated under various ion species and angular conditions. The results demonstrate radial track structure and device geometry, rather than LET alone, govern upset multiplicity and angular dependence.
