Radiation Induced Single-Event Effects for SRAMs at Advanced Technology Nodes

Every storage cell on an IC fabricated at advanced technologies is susceptible to radiation-induced data errors, known as single-event upsets or soft errors. Single-event upsets are the result of energy deposition by an energetic particle incident on a semiconductor region.  Proliferation of electronic systems in everyday life has necessitated evaluation of single-event effects on storage cells to characterize failure rates of these systems. Out of all storage cells, SRAM cells are most vulnerable to single-event effects due to very low critical charge values.  Improvements in fabrication processes have resulted in a mixed bag of results.  This talk will examine the effects of strain engineering and FinFET physical shape on single-bit and multi-cell upsets for SRAM arrays.
