Instrument Facilities
Lab of chemistry professor Luis A. Colon in the Natural Sciences Complex
INS maintains a set of centrally-coordinated instruments that
supports research in nanoscience, as well as related physics,
engineering, and materials research. All facilities are available
to both UB faculty and external users, for modest cost-recovery
fees.
Additional support for the facility comes from the UB Office of
the Vice President for Research, the UB School of Engineering, and
the UB College of Arts and Sciences. Individual instruments and
instrument clusters are described below. For further information,
contact Dr. Mark Swihart at swihart@buffalo.edu.
High Resolution Transmission Electron Microscopy Facility (HRTEM)
The High Resolution Transmission Electron Microscopy facility
(HRTEM) of INSIF is a central, shared facility for
microanalysis. The facility provides microanalysis services to both
researchers on the UB campus, as well as off-campus industries and
other institutions in the region. The HRTEM staff will provide
assistance and training in electron microscopy techniques to enable
research groups to pursue their research objectives.
The JEOL JEM 2010 is a high-resolution electron microscope with
an accelerating voltage of 200KV, and a point resolution of 0.19
nm. It is equipped with a 5-axis micro-active goniometer, which
makes micro-structural analysis possible for many kinds of
crystalline materials. The TEM provides morphology images, in
either bright or dark field and the correspondingcrystal
structuresby electron diffraction; Additionally there are two
different modes of operation: the Convergent Beam Diffraction (CBD)
modeis very helpful in analyzing crystal symmetry, while theNano
Beam Diffraction (NBD) modewill provide the crystal structure for
nano-particles. A new Gatan CCD camera and associated Digital
Micrograph software was installed in Summer 2008, providing
improved lattice-resolution HRTEM capabilities and a variety of
automated measurement capabilities, including real-time video
recording. Sample preparation tools (wire saw, dimpler,
polishers, etc.) are also available.

Focused Ion Beam/Scanning Electron Microscopy Facility
The FIB/SEM facility consists of a Zeiss Auriga XBeam focused
ion beam/field-emission SEM system with TEM liftout, Oxford EDS
system, Avizo imaging interface/software for 3D reconstruction of
depth profiles, etc. Key capabilities of this system include:
- Electron beam (E-beam) and focused ion beam (FIB)
nano-lithography
- Precise preparation of cross-sectional samples for transmission
electron microscopy (TEM)
- 3D tomography: 3D visualization with nanometer-scale
resolution
- High resolution Field-emission-SEM and FIB imaging
- Energy-dispersive x-ray spectroscopy to analyze material
composition (with nm resolution)
- Gas injection for both etching and deposition of both
conducting and insulating materials

The Clean Room Facility
The Clean Room Facility of INSIF provides optical lithography
and device processing, fabrication, and testing. It provides a
range of fabrication and processing capabilities to UB researchers,
as well as external users, in conjunction with our faculty.
Capabilities:
The CRF consists of a 300 sq. ft., class 100 space with
controlled humidity and temperature, coupled with an adjacent,
class 1000 room without humidity and temperature control. The class
100 room contains the following: a chemical process station,
several ovens, thermal and e-beam evaporators, a mask-aligner, a
reactive ion etcher, and a photoresist spinner. Additionally, the
recently completed class 1000 room presently contains: a
Plasma-assisted Chemical Vapor Deposition System, a three-zone
furnace, and a four-point probe resistance tester.
A sub-micron probe station and our cryogenic systems allow
testing of current-voltage temperature,
capacitance-voltage-temperature, deep-level transient spectroscopy,
and quasistatic C-V.
These facilities permit deposition of thin films of most
dielectric and metallic materials through one of the following
processes:
- one of the evaporation techniques
- fabrication of electron devices with feature sizes greater than
2 microns
- electrical analysis of materials and devices
Facilities in addition to the clean space:
- Samco IC Reactive Ion Etcher
- Integrated Technologies P-8000 Photoresist Spinner
- Chemical Bench
- Denton DEG-2 e-beam Evaporator
- Denton DV502 Thermal Evaporator
- Oriel Mask Aligner
- Gaertner Ellipsometer
- Alessi 4-point Probe
- Trion-Orion Plasma Enhanced CVD System

Device Bonding
A K&S Model 4522 Digital Ball Wire Bonder supports the
various fabrication and characterization labs of INSIF. This is a
ball-bonder type machine that can store various wire bonding
“recipes.” It can bond with gold wires from 18-75
microns in diameter. The machine is located in 210 Bonner Hall on
UB’s North Campus.
