The recipients of the 2001 Outstanding Conference
Paper Award are Paul Dodd, Marty Shaneyfelt, Kevin Horn, Dave Walsh,
Gerald Hash, Tom Hill, Bruce Draper, Jim Schwank, Fred Sexton and
Peter Winokur of Sandia National Laboratories for their paper entitled
"SEU-Sensitive Volumes in Bulk and SOI SRAMs from First-Principles
Calculations and Experiments”. In this paper, the authors used large-scale
3D simulations, broadbeam experiments and focused ion microscopy
to study several aspects of SEU-sensitive volumes in bulk and SOI
CMOS random-access memories. SEU maps and cross-sections calculated
from 3D simulations were found to be in excellent agreement with
measured broadbeam cross-section curves and microbeam charge collection
and upset images for bulk CMOS SRAMs. Experimental studies of SEU
in SOI SRAM's showed unexpectedly large charge collection following
drain region ion strikes. The authors found that this drain region
charge collection can lead to SEU-sensitive volumes in SOI integrated
circuits that can include the reverse-biased drain regions. This
finding is in contrast with the generally accepted assumption that
only gate region ion strikes cause upset in SOI circuits. This mechanism
may increase the sensitive area and hence the error rate by as much
as a factor of ten. The authors postulated that the drain charge
collection is due to charge transfer from the substrate to the active
silicon area via ion-induced conductive pipe defects in the buried
oxide.
The Meritorious Conference Paper Award for NSREC-2001
was given to Lloyd Massengill, Bo Kyoung Choi, Dan Fleetwood, Ron
Schrimpf and Ken Galloway of Vanderbilt University, Marty Shaneyfelt,
Tim Meisenheimer, Paul Dodd and Jim Schwank of Sandia National Laboratories
and Yi-Mu Lee, Robert Johnson and Gerry Lucovsky of North Carolina
State University for their paper entitled œHeavy-Ion-Induced Breakdown
in Ultra-Thin Gate Oxides and High-k Dielectrics”.
Both the Outstanding and Meritorious papers were published
in the December issue of the IEEE Transactions on Nuclear Science.
The Radiation Effects Data Workshop provides a forum
for the presentation of radiation response and test facility data
of interest to members of the community, while the Workshop Record
serves as a ready reference for detailed radiation effects data.
This year, one 2001 REDW poster presentation was selected as the
Outstanding REDW Presentation. This award-winning presentation is
entitled "Recent Radiation Damage and Single Event Effect Results
for Candidate Spacecraft Electronics” and provides a highly usable
compendium of test results for a wide variety of electronic devices.
The presentation's authors are Martha O'Bryan, Christina Seidleck
and Martin Carts of Raytheon ITSS, Ken LaBel, Robert Reed, Janet
Barth, Cheryl Marshall, Donald Hawkins, Anthony Sanders and Steve
Cox of NASA Goddard Space Flight Center, James Howard, Jr., Hak
Kim, James Forney, and Curtis Dunsmore of Jackson and Tull Chartered
Engineers, Steve Buchner and Paul Marshall of SFA, Inc., and Christopher
Palor, Ray Ladbury and Scott Kniffin of Orbital Sciences Corporation.
The long list of authors that contributed to this presentation shows
ample evidence of the close collaborations between the broad range
of organizations they represent.
