The impact of technology trends on the SEU hardness of epitaxial CMOS SRAMs is investigated using three-dimensional simulation. We study trends in SEU susceptibility with parameter variations across and within technology generations. Upset mechanisms for various strike locations and their dependence on gate-length scaling are explored. Such studies are useful for technology development and providing input for process and design decisions. An application of SEU simulation, to the development of a 0.5-μm radiation-hardened CMOS SRAM is presented
