Q150T Sample Preparation System
10473 -Issue 58Q150T -Instruction Manual
1Introduction
1.1 General Description
The Q150T system is a versatile sputter coater/turbo evaporator (see Figure 1-1) for
preparing specimens for examination by electron microscopy.
With a comprehensive selection of easily interchanged inserts and sample stages, the
Q150T can be used to:
Sputter coat samples using targets such as Chromium or Gold.
Evaporate support films and replicas for TEM and X-Ray analysis and conducting
coatings for SEM using 3mm or 6mm carbon rods or cords.
Evaporate metals upwards or downwards from a wire basket or molybdenum boat
arrangement.
Clean aperture strips.
There are three models in the Q150T range:
Q150T SSputter coater version only.
Q150T ECarbon/metal evaporation version only.
Q150T ES Combined system with interchangeable inserts for sputter coating or
carbon/metal evaporation.
The instrument is fully adaptable to a wide range of specimens and offers easy loading
and unloading of samples. The changeover between sputtering and evaporation inserts
is simple. The system is fully automated with a user defined profile controlling the
pumping sequence, preheating, outgassing, the time and number of evaporation/sputter
bursts, and the current used during the process.
The Q150T can be fitted with afilm thickness monitor (FTM), which measures the
coating thickness on a crystal in the chamber, to control the coating applied to the
sample. For example, the Q150Tcan automatically terminate a coating cycle when the
required thickness has been achieved.
Figure 1-1. Front view of the Q150T
The Q150T features a turbo molecular pump backed by a rotary vacuum pump and
controlled by the instrument throughout the fully automatic coating cycle.
The system is fitted with a vacuum shutdown system allowing the instrument to be
pumped down and switched off, with the chamber left under vacuum.

Q150T Sample Preparation System
Q150T -Instruction Manual 910473 -Issue 5
1.2 Sputter Coating
Sputter Coaters are used in Scanning Electron Microscopy to provide an electrically
conductive thin film representative of the surface topography of the specimen to be
viewed, such films inhibit 'charging', reduce thermal damage, and enhance secondary
electron emission.
The Q150T S and Q150T ES employ a magnetron sputter target assembly.This
enhances the efficiency of the process using low voltages and giving a fine-grain (order
of 0.5nm Cr grain size), cool sputtering. The unit features a rotating sample table
ensuring even depositions (typically 5nm). It uses standard targets,avoiding the
necessity of special large profile targets. The instrument is fitted with a 57mm diameter
quick-change target (the sample chamber is 165mm in diameter) giving optimum
consumable cost performance. Alternative target materials are available.
A shutter assembly is fitted as standard, which allows sputter cleaning of oxidising
targets.
1.3 Carbon Coating
Carbon films, because of their mechanical stability, good electrical conductivity, and low
background signal are commonly used to prepare samples for Electron Microscopy
(EM).
Thin films of about 5 nm (50A) are used for particle support and as an isolating layer in
autoradiography. Thicker films are used in Scanning Electron Microscopy (SEM) also for
support, in addition to coating for X-Ray Microanalysis. In general, there is a need for all
these films to be fine grain, even coating, with uniform and reproducible film thickness.
The most common form of deposition is from resistance heated carbon rods. The rods
are shaped to achieve high current density with sufficient temperature to cause
evaporation. Carbon filaments can also be used, which at high temperature burn quickly,
from which has evolved the terminology: Carbon 'Flash' Evaporation. The resulting short
coating times and reduced total power input distinguishes it from the somewhat longer
process of carbon rod evaporation.
Q150T E and ES models feature a multi-change head system for Carbon rod, Carbon
fibre and metal evaporation.
1.4 Metal Evaporation
By vaporizing a metal film onto a sample, it is possible to enhance the topographic detail
for high resolution analyses by TEM or SEM. This technique is particularly useful in the
analysis of biological specimens. The metal evaporant, usually a wire of, for example,
platinum or gold, is heated and vaporised by a filament (typically made of tungsten).
For downwards evaporation, evaporants usually in the form of wire: e.g gold, platinum,
aluminium,etc are placed directly onto the filament. For upwards evaporation, the
evaporant is placed in a ‘boat’(typically made of molybdenum or tungsten).
The Q150T E and ES can be configured for metal evaporation in an upwards or
downwards direction.
1.5 Aperture Cleaning
In its metal evaporation configuration,you can use aQ150T E or Q150T ES to clean
aperture strips and other electron microscope components. With the component placed
in a molybdenum boat, it can be heated to evaporate contaminants.

2Installation
It is important that this equipment is installed by skilled personnel in accordance with
these instructions. Failure to do so may result in damage or injury. 'If in doubt -ASK'.
2.1 Pre-installation
Identify a suitable location for the unit:
Mount the unit on a bench or the recommended trolley. The total weight of the system
is 33.4 kg.
The environment should have an ambient temperature range of 15ºC to 25ºC in a
non-condensing relative humidity of not more than 75%.
Sufficient ventilation is required, and positioning should be out of direct sunlight.
The system is rated for continuous operation.
2.1.1 Required Services
Argon
Supply for sputtering should be N4.8 (Zero Grade) 99.998% purity capable of supplying
3 litres/min at 4 psi. The regulator should be set at 4 psi.
The system is supplied with 3m plastic tubing 3mm I.D. x 6mm O.D. from a quick
release connector on the rear of the unit. It is the customer’s responsibility to connect
this tube to the pressure regulator from the gas bottle or plant supply. Typically a system
will use approx. 0.2 litres of Argon for a 4 minute sputter cycle (plus up to 4 litres if argon
is also used for purging and venting).
If bottle supply is adjacent it can be isolated locally, if not or plant supply,
local isolation valves should be fitted.

1. Connect a suitable argon supply at a regulated input of 0.3bar (4psi) to the quick
connect Argon gas connector on the rear panel (see Figure 2-1. If you prefer, you
can use argon for both process and purge supplies.(recommended if coating with
oxidising targets). To do so, install a 'T' piece across both gas inlets.
2. Connect a suitable nitrogen supply at a regulated input of 0.3bar (4psi) to the
quick connect Nitrogen connector on the rear panel. Air may be used in place of
nitrogen for venting (not recommended for oxidising targets) but it is important to
fit the filter (part no. 12842)to prevent ingress of dust (see Figure 2-2). Failure to
connect this filter could prevent the system venting at the end of a cycle.
Connectors are push-fit and will 'snap' into a locked position. To release a connector,
depress the metal tongue.

2.3.4 Vacuum Connections
1. If you are using an existing or alternative vacuum pump, and have any difficulty
with connections, please ask for advice.
2. If the instrument is NOT going to be vented into an extraction system, fit an Oil
Mist Filter with metal adapter to the outlet of the vacuum pump. Please refer to
the manufacturer’s instructions.
3. Ensure that the vacuum pump is filled with the correct oil.
4. If the vacuum pump is fitted with an on/off switch, ensure that it is set to the 'on'
position to allow the instrument to control its power supply.
5. Connect the flexible vacuum hose to the spigot on the rear panel using the hose
clip provided. This is a push-on fit to the Instrument. Ensure that this is firmly in
place to the full length of the spigot.
A rotating vacuum spigot is available for more convenient hose
connection in installations where the instrument is to be located close

2.3.5 Fitting the Standard Stage
The Q150T is supplied with a standard stage (10067). For installation instructions for
other stages, see page 54. To install the standard stage:
1. Ensure that the instrument is vented and in standby mode.
2. Open the top cover fully so it rests against its backstop.
3. If there is already a stage in place, remove it by lifting carefully upwards.
4. Fit the standard stage by locating its shaft into the top of the stage rotation drive
spigot protruding from the baseplate and with a twisting motion pushing it gently
down until the collar around the shaft rests on top of the drive spigot (see below).
Figure 2-4. Fitting the standard stage
You can adjust the height of the stage above the base plate by moving the
collar up or down the shaft. Unfasten the M3 screw with a hexagonal key,
slide the collar to the required position and retighten the M3 screw.
For maximum distance between the stage and the target, remove the collar
so that the underside of the stage restson the top of the drive spigot. To
reduce the distance between the stage and target, fit the stage with the
alternative long shaft (10214 –supplied with stage).
When using small 1/8” pin stubs, it is advisable to unscrew the stage and fit it
upside down for easy access to the stub.
Note that the Q150T’s default tooling factors are based on a stage
height of 60mm from the base plate.
2.3.6 Optional Connections
For full connection details of optional units, where provided, please refer to separate
instructions. Any other connections on the rear panel not listed are for common
manufacturing and are not available for this instrument.
