Predicting Thermal Neutron-Induced Soft Errors in Static Memories Using TCAD and Physics-Based Monte Carlo Simulation Tools

A combination of commercial simulation tools and custom applications utilizing Geant4 physics libraries is used to analyze thermal neutron induced soft error rates in a commercial bulk CMOS SRAM. Detailed descriptions of the sensitive regions based upon technology in computer-aided design calibration are used in conjunction with a physics-based Monte Carlo simulator to predict neutron soft error cross sections that are in good agreement with experimental results
