COMMERCE BUSINESS DAILY ISSUE OF MAY 10,1995 PSA#1343TECHNOLOGY TRANSFER OPPORTUNITY The U.S. Department of Energy (DOE),
its laboratories, and production facilities are committed to helping
businesses in the United States to improve the cycle from new ideas and
product innovation to product development and commercialization. In
order to achieve this goal, the DOE has put in place a program to make
technological capabilities developed at its laboratories available to
the private sector for commercial applications. Sandia National
Laboratories (Sandia) is one of the participating laboratories in this
program. Over the past three decades, the Ion Beam Materials Research
Laboratory, (IBMRL), User Facility at Sandia National Laboratories has
developed at unique set of Ion Beam Analysis, IBA tools which have been
found to be particularly useful in the US Defense Mission at Sandia.
These IBA techniques are now being made available for industrial or
university research applications via the designation of this
accelerator laboratory as a Technology Deployment/User Facility. The
IBMRL facility is based around a Pelletronized 6MV terminal Tandem Van
Graaff accelerator to which we have recently added a 1.9 MeV/amu Radio
Frequency Quadrupole Heavy Ion linac booster. Some of the facilities
which are available include: 1. Heavy Ion Backscattering Spectrometry
(HIBS), a joint SNL-SEMATECH project, which has shown sensitivity to
surface metal impurities on Is wafers of less than 10 atoms/cm. A
stand-alone prototype HIBS system now exists which can be used to
examine multiple spots on 4'' - 8'' diameter IC wafers. 2. Time of
Flight Elastic Recoil Detection (TOF-ERD) can be used to depth profile
major elements in the near-surface (100nm) of solids with
extraordinary depth resolution, approaching 1 nm at the surface. Since
Au ions are used for the incident beam, virtually all of the elements
in the periodic table can be examined this way. 3. Nuclear Enhanced
Backscattering Spectrometry is really just like RBS, but relies on the
high energy ions which can be accelerated on the tandem, and is
particularly effective in profiling light elements (say the second row
of the peiodic table) in heavier matrices. The high energies make this
possible by enhancing the cross section of scattering from the light
elements, while decreasing the scattering from the heavier substrate
atoms. 4. All of the routine IBA techniques can be performed on a
scanned nuclear microbeam which has a 1-2 micron beam spot. In
addition, several of these IBA techniques have been done externally,
i.e. in air, by extracting the beam from the vacuum system through thin
foils. Such external IBA, or X-IBA, can be quite advantageous when
analyzing extremely large samples, or materials which are not
compatible with vacuum systems. Our X-IBA system won an R&D 100 award.
5. Another analytical tool which has been included in the IBMRL User
Facility is a Double Crystal X-ray Diffractometer and 3D-Reciprocal
Space Mapping system which can be used to measure in-depth strain
profiles. This tool has particular utility in Sandia's compound
semiconductor research program. We are seeking industrial or university
participants. To express interest, please write or fax to Sandia
