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.

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 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

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.

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.

on the ion milling process can be automated by using

the sophisticated automation routines provided in

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

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
