New simulation methodology for effects of radiation in semiconductor chip structures

New and effective modeling methodologies have been developed to stimulate particle transport in arbitrarily complex back-end-of-line (BEOL) topologies of a semiconductor chip. They are applied to address a number of critical problems that involve the single-event-effect analysis of new device structures for 65-nm CMOS (complementary metal-oxide semiconductor) technologies and beyond. These new simulation techniques also provide a generic building block on which a new version qf the IBM soft-error Monte Carlo model (SEMM-2) is constructed. In this paper, we review the basic concepts of this development and discuss some important applications. © Copyright 2008 by International Business Machines Corporation.
