CrossBeam®1540XBThe ZEISS 1540XB CrossBeam® combines the advan-
tages of the ultra high resolution, low dose GEMINI®
Field Emission Scanning Electron Microscope (FESEM)
with a high-performance, focused ion beam (FIB)
system. Applications are as diverse as subsurface root
cause failure analysis, high precision TEM sample
preparation, nano-structuring and E-beam lithography.
The system consists of live E-beam imaging during
FIB operation, a compact, five-channel gas injection
system and a large ultra-precise specimen stage, satis-
fying even the most demanding applications. It is a
state-of-the-art combination of real-time 3D analysis,
nano-scale manipulation and an imaging tool.
CrossBeam®1560XBThe large chamber system with the refined 6" super
eucentric stage and the 8" integrated airlock offers the
perfect solution for full wafers and cross sectional
semiconductor applications, and for users who need to
analyse a variety of large samples.
● Ultra high resolution FESEM with unique GEMINI®
column and high performance CANION FIB column

Nano-scale 3D Analysis Tool
CrossBeam®1540EsBThe 1540EsB CrossBeam® tool comprises a fully
integrated Energy and angle selective Backscattered
electron (EsB) detector. The instrument offers ultra
high resolution for surface sensitive SE imaging and
compositional information through BSE imaging. The
new EsB detection principle features an integrated
filtering grid to enhance the image quality and requires
no additional adjustments. The EsB detection principle
is less sensitive to edge contrast and charging effects.
Therefore the accuracy in measurements of interfaces,
particles and features is increased.
● Ultra high resolution FESEM with unique GEMINI®
column and high performance CANION FIB column
● High efficiency EsB detector for compositional
information
● Ultra high resolution BSE imaging at very short
working distances
● Excellent Z-contrast for optimum analytical
information
● Ideal for precise interface, particle and feature
measurements

CANIONThe CrossBeam® series make use of the high perfor-
mance CANION FIB column. The superior ion optical
concept of the CANION FIB column provides excellent
resolution, high current densities and a large beam
voltage range between 3 kV and 30 kV. The ion beam is
generated in a high brightness LMIS (liquid metal ion
source) and focused onto the specimen by an opti-
mised electrostatic two lens system. Stabilization of the
emission current and the selection of different probe
currents is totally computer controlled. This gives the
user full advantage in automation processes and ease
of use. All alignments for different probe currents and
beam voltage settings are stored via the SmartSEMTM
operating system and can be easily selected by a click
of a button. An integrated Faraday cup allows accura-
te probe current measurements during the operation.

System LayoutThe CrossBeam® tools combine the
imaging and analytical capabilities
of a high resolution field emission
SEM (FESEM) with a high perfor-
mance FIB column into one inte-
grated instrument. In the case of
the CrossBeam® tool the final lens
of SEM is designed as a magne-
tic/electrostatic compound lens.
This layout has the advantage that
no magnetic field interferes with
the ion beam and the SEM can be
operated at nm resolution during
the ion milling process. This layout
allows full control over the total
process and gives an excellent end-
point detection and cut localization
for defect review and failure ana-
lysis.
Together with a multi-channel gas
injection system for metal and
insulator deposition and for enhan-
ced and selective etching the
CrossBeam® workstation is a very
powerful analytical and imaging
tool for a wide range of appli-
cations within the semiconductor
industry as well as for material
science and life science appli-
cations.

Chamber DesignThe flexible chamber design of the
CrossBeam® tools provides full
compatibility to all analytical requi-
rements. Two CCD cameras monitor
the inside of the specimen chamber
to provide the operator with full
information when handling large
and special shaped samples. Many
additional ports provide the capa-
bility of adding various detectors,
airlocks and analytical equipment
making the CrossBeam® system the
ultimate 3D analysis tool.
Imaging ModesA CrossBeam® tool can operate at
three different imaging modes. By
blanking the ion beam and only
using the electron beam for imaging
the system operates as a high
resolution field emission SEM. The
second imaging mode uses the ion
beam while the electron beam is
blanked. This FIB imaging mode is
used for grain analysis, voltage con-
trast imaging and defining of mil-
ling areas. The last imaging mode is
the so called CrossBeam® operati-
on mode: Both beams are turned on
and while the ion beam is milling a
defined area, the SEM is used to
image the milling process at high
resolution in real time. This enables
the operator to control the milling
process on a nanometer scale and
to perform extremely accurate cross
sections and device modifications.
If the system is used as a
high resolution SEM only
the ion beam is blanked
and the SE signal is syn-
chronized to the SEM scan.
In this operational mode
the system can be used as a
high resolution FESEM with
no limitations.
If the system is used as a
FIB, only the SEM beam is
blanked and the signal is
synchronized to the FIB
scan. This mode is used for
channelling contrast ima-
ging, voltage contrast ima-
ging and for defining mil-
ling patterns on the sample
surface.
Both beams are scanned
completely independent of
each other and the SED
Signal is synchronized to
the SEM scan. This results
in the CrossBeam® opera-
tion feature: The ion milling
process can be imaged
using the SEM in real-time.

Dramatic reduction of objective lens aberrations in the low kV range.

GEMINI®
The CrossBeam® has been built around the unique GEMINI®
lens design which has many advantages over classical lens
designs:
The most important feature is the decreasing aberrations with
decreasing beam energy. Therefore it delivers superb resolution
down to 100 V and at 30 kV its resolving power is unsurpassed.
The high-angled GEMINI® objective lens body allows 56° tilt of
large specimens (e.g. 6" wafers) at a working distance as low
as 5mm. The analytical working distance for EDS analysis with
a take-off angle of 35° is only 5 mm - suitable for high resolu-
tion imaging. The GEMINI® objective lens consists of a high
performance magnetic lens with an inserted electrostatic lens.
The GEMINI® concept has overcome the problem with classical
objective lens designs which immerses the specimen in the
magnetic field prohibiting imaging of magnetic samples. The
GEMINI® magnetic lens is shaped to minimise the magnetic
field at the specimen. Therefore high resolution imaging of
dia-, para-, or ferromagnetic samples is possible with very
short working distances.
The magnetic/electrostatic lens combination is equivalent to an
optical lens triplet which increases the incident beam aperture
angle at the specimen and hence improves resolution. The
increase of the optimum beam aperture angle also provides a
larger electron probe current and hence generates a superior
signal to noise ratio of the image. The lens control system with
integrated condenser control will always select the optimum
beam aperture for any combination of working distance and / or
selected energy. Consequently the FESEM delivers excellent
image contrast even at the resolution limit. A single-stage
beam scanning system is integrated in the GEMINI® lens, just
in front of the electrostatic lens gap. Therefore, the transverse
chromatic and other scanning aberrations have been mini-
mised. The instrument operates without distortion at TV-scan-
ning speed from the lowest (12 x) to the highest (900,000 x)
magnification. In particular, no switch-over is required bet-
ween a low magnification mode and a high resolution mode.
The GEMINI® objective lens provides outstanding
resolution and image quality, especially at low
beam voltages, without any compromise in opera-
tional convenience.

The CrossBeam® workstations deliver extraordinary
results for semiconductor applications. The CrossBeam®
workstations are designed to meet the most deman-
ding applications of failure analysis and process de-
velopment. Imaging of nonconductive samples, cross
sections and voltage contrast applications are no
problem for the CrossBeam® workstations.
The use of various detector signals and primary beams
simultaneously opens up new dimensions of informati-
on about the sample. While the electron beam genera-
tes ultimate high resolution information about the
sample surface and composition, the ion beam provi-
des data for voltage contrast and channelling contrast.
The excellent low voltage imaging capabilities of the
GEMINI® SEM column make the CrossBeam® the ideal
tool to image photo resist, polymers, oxides and other
non conductive samples in their natural state in high
resolution.

For material science applications in nanotechnology,
developing new materials, processes and materials
characterization the CrossBeam® tools offer the most
versatile combination of an ultra high resolution
FESEM and an ultra high performance FIB.
Non conductive samples
Due to its natural charge compensation concept (SEM
and FIB simultaneously) the CrossBeam® tool is able to
cut into non conductive material in its natural state
without coatings. This makes quality and process
control on interfaces between conductive and noncon-
ductive material extremely easy.
Material Science Applications
Higher magnification of the details reveal the origin of the defect at the interface between substrate and coating. By using the live imaging capabilities of the CrossBeam® tool the milling process can be stopped exactly at the position of interest.

Site specific investigation of interfaces and buried
layers
In many industrial applications coatings of certain
surfaces show faults. To investigate the problem in
the coating process and to find the origin of conta-
mination or a process failure a dedicated site specific
failure analysis is needed. In the example below a DLC
coating showed uniform bubbles on the surface. To
find the process step that caused the problem the
sample was cut in the CrossBeam® tool and by using
the real time imaging capability, the cause of the pro-
cess failure could be found easily.

To investigate everyday samples the

To investigate the embedding of implants into bone
tissue and connective tissue, or the coupling of recor-
ding or stimulation electrodes to neural tissue, the
precise knowledge of the interface (structure, chemical
composition, internal layers, etc.) between cell tissue
and implant or electrode material is essential. In elec-
tro-physiology the exact knowledge of the interface
between cell tissue and stimulation or recording elec-
trodes contributes to the interpretation of the recorded
signals. Furthermore the understanding of mechanisms
influencing the behavior of cells on micro structured
surfaces could help to optimize the surface of future
implants.
The investigation of the interface between cell tissue
and hard materials like silicon etc. is mostly limited to
the investigation of epoxy replicas of the microstruc-
tures. This is due to the limitations of the ultramicro-
tomy technique for cutting hard materials like silicon,
glass, ceramics etc.

To overcome the disadvantages of the microtome,

nique that allows a site specific investigation of the
real interface between silicon microstructures and cell
tissue at high resolution in a CrossBeam® tool.

Sample preparation
Fibroblasts were cultured on titanium coated Si micro-
structured Si wafers. The wafers were sterilized in 70 %
ethanol, exposed to UV light and incubated in tissue
culture medium overnight before seeding the cells.
The cells were then washed in buffer, fixed in 2.5 %
buffered glutaraldehyde (pH 7.4) for 30 min, postfixed
in 1 % OsO4 and dehydrated in a series of ethanol.
The 70 % ethanol step was performed with ethanol
saturated with uranyl acetate. After dehydration, the
specimens were embedded in Araldite.

Gas Chemistry
The CrossBeam® instruments provide a full solution for
sophisticated gas chemistry. An integrated 5 channel
gas injection system (GIS) provides full capability for
metal and insulator deposition, enhanced etching,
device modification etc. The GIS is designed for easy
operation and quick changes of the operating gas.

Deposition applications
Metal and insulator depositions are used for various
purposes. Examples are protective layers for TEM sam-
ple preparation, conductive connecting layers between
electrodes or the generation of probing and contact
pads on computer chips.
16
Deposition Process: the incoming precursor molecules are adsorbed to the substrate surface. If a precursor molecule is hitby a charged particle beam, the molecule is decomposed and the central ion is bound to the surface. It is possible to use theion beam or the electron beam for deposition.

Reactive etching
To avoid redeposition of sputtered material and to
enhance the milling rate on many materials the GIS is
used for inserting special precursor gases into the spe-
cimen chamber. These form volatile reaction products
with the substrate after being activated by the ion
beam.
Gas Chemistry

For applications in the micro cosmos e.g. optical cou-

put a high demand on micro machining capabilities.
The CrossBeam® tool is the ideal instrument to provide
micro machining and micro patterning solutions for
current and future nano scale applications.

If microstructures need to be connected for optical
information exchange, high precision micro optics are
needed.

can be integrated into the CrossBeam® tool. This
converts the instrument into a nano workbench.
For electrical current measurements on small semi-
conductor devices nano probing modules are needed.
By integrating these modules into the CrossBeam® tool
measurements on a nanometre scale become possible.
Electrical measurements can be carried out even down
to the sub nA-range on microelectronics devices.

during preparation is reduced to a minimum. In additi-
on the ion milling process can be automated by using
the sophisticated automation routines provided in
SmartSEMTM.

The lamella is transferred to a TEM grid and welded to thegrid by using the metal deposition of the GIS.
Final step: After cutting off and retracting the tip, the sample isthinned to electron transparency.
As the sample gets thinner the primary electrons start
penetrating the sample and generate secondary elec-
trons on the reverse side. These electrons can be detec-
ted by using the Everhart-Thornley detector which is
geometrically located behind the sample. This signal
gives direct information about the thickness of the
sample: The thinner the sample, the brighter the
image. At the same time the sample surface can be
imaged using the In-lens detector which is geometri-
cally located in front of the sample and collects mainly
secondary electrons which are emitted from the sample
surface. By combining both signals during the ion
milling in a split screen mode all of the sample data
(location, surface detail and thickness) can be dis-
played at the same time.

By using a STEM (Scanning Transmission Electron Microscopy)
detector the information limit for the CrossBeam® FESEMs can
be extended beyond the nanometer range. A resolution of
0.8 nm at 30 kV is now readily attainable and gives additional
nano-scale information. The resolving power of the
CrossBeam® FESEM can be used to save processing time on
TEM systems for high resolution applications and enables high
sample throughput for quality assurance applications and
routine type measurements.
Typical application fields are:
● Materials analysis (polymer, ceramics, nanoparticles)
● Semiconductors (FIB lamellas from devices)
● Life science (histology, pathology)
The newly developed proprietary CrossBeam® Multi-Mode
STEM detection system delivers enhanced image quality by
real-time simultaneous detection of BF, DF, and orientated DF
signals, without realignment at any position.
CrossBeam® Multi-Mode STEMThe CrossBeam® Multi-Mode STEM detection system comprises
two parallel diode detector surfaces. The DF detector surface
has been divided into specific areas to allow orientated DF
imaging. The specimens are mounted in a carousel type TEM
grid holder, which holds 6 specimens. The CrossBeam® Multi-
Mode STEM detector includes a complete retractable assembly
with high precision adjustments for optimum alignment and
can be used in combination with all CrossBeam® detectors.
Advantages of the Multi-Mode STEM detector:
● Simultaneous imaging of BF and DF
● Orientated DF mode (ODF)
● STEM resolution down to 0.8 nm at 30 kV
● Ease of use with high precision positioning
● Long-life diode detector system
● Imaging of stained and unstained samples

Signal EnhancementDue to the significantly lower electron beam energies used in
the SEM, the beam-specimen interactions are much stronger.
This enables the possibility to explore subtile contrast mecha-
nisms. The STEM detector enables pure BF or DF imaging to
achieve optimum contrasts and rich imaging details of even
unstained thin sections. Furthermore it also allows EDX analy-
sis of particles down to 30 nm or less. The unique parallel STEM
detector arrangement allows simultaneous imaging and mixing
of BF, DF and orientated DF STEM signals on any position of
the TEM specimen without realignment.
The CrossBeam® Multi-Mode STEM detection system
allows the following six imaging modes:
● BF
● BF and DF added
● DF
● BF and DF subtracted
● ODF
● ODF1 and ODF2 subtracted

tion system and signal processing is controlled by
