Alpha-particle-induced upsets in advanced CMOS circuits and technology

View publication


In this paper, we review the current status of single-event upsets caused by alpha-particles in IBM circuits and technology. While both alpha-particles and cosmic radiation can induce upsets, the alpha-particle-induced upset rate has become an increasingly important issue because alpha-particle- induced upsets are no longer limited to memory circuits. Latch circuits have become highly sensitive to alpha-particles. The alpha-particle-induced upset rate of latch circuits is one of the most critical issues for microprocessors requiring both high performance and high reliability. © Copyright 2008 by International Business Machines Corporation.
