SPUTTER COATERS
Quorum/EMITECH's range of sputter coaters includes the K575X , K650X , K675X and K695X . The K695X is able to coat single 12" wafers in one operation, and with its unique sputtering arm can sputter two different target materials sequentially.

These units are all benchtop units utilising magnetron target assemblies. The magnetron target assembly enhances the efficiency of the process using low voltages and results in fine grain and cool sputtering.
All units are designed with an integrated panel and plug-in electronics to maximise up-time. All systems are engineered for easy operation and they are well suited for multi-user environments. The independent rotary pumps are controlled by the instruments throughout the process.
The K575X uses a 'Turbo' pump, backed up by a Rotary Vacuum pump, the complete pumping sequence being under automatic control, the vacuum in the order of 1 x 10 -3 mbar.
The twin head version of the above, the K575d has two sputter heads. These are arranged such that, for special coating applications, two sequential layers of a target material can be deposited without breaking the vacuum seal in this automatic unit.
The K675 system employs a magnetron target assembly which enhances the efficiency of the process using low voltages, and giving a fine grain, cool sputtering. There are three such target assemblies in the K675X, positioned to give coating over a large diameter which, together with a rotating sample table, ensures even depositions. This method allows standard targets to be utilised, and avoids the necessity of special large profile targets.
The triple-target system is particularly useful in the semi-conductor wafer industry. It has a turbomolecular pump backed by a rotary vacuum pump. The integrated instrument panel and plug-in electronics maximise 'up-time' and, with user friendly designs, ensures satisfactory multi-user discipline. The sputtering parameters can be pre-set, including the gas bleed needle valve which has electromagnetic valve back-up.
The independent vacuum pump is controlled by the instrument throughout the fully automatic coating cycle.
It can be used to sputter coat targets such as gold, and also targets that may need pre-cleaning, or the removal of oxide layers such as chromium. A shutter assembly is fitted as standard which allows a sputter cleaning and the sputter cycle to be carried out while maintaining the vacuum.

Notes on SPUTTER COATING
When a glow discharge is formed between a Cathode and Anode using a suitable gas (typically Argon), and Cathode target material (commonly Gold) the bombardment of the target with gas ions will erode this target material, this process being termed "Sputtering".
The resulting omni-directional deposition of sputtered atoms will form an even coating on the surface of the specimen, normally located on the stage (anode) of the instrument. This electrically conductive thin coating will be representative of the surface of the specimen. It will inhibit charging, reduce thermal damage, and improve secondary electron emission which are beneficial for Scanning Electron Microscopy.


FAQ: How to mount targets in a sputter coater
Most targets are held by a cover or crimped around the edge - if yours is not that type it must be glued.
'Glue' used must be electrically conducting.
For 'professional' mounting use a few slivers of indium wire on the support plate, cover with the target and then either place in an oven with a flat weight on top of the target or use a smoothing iron to heat the gold and hence melt the indium. Placing something like a piece of lens tissue onto the target would protect it.
For a short time a temperature a little higher than melting point of Indium is required; m.p. 156.6ºC.
Alternatively use a bit of silver conducting paint, best find a few small drops of paste at the bottom of the jar.
You could also make a paste using our silver powder and a little commercial epoxy glue - method under Silver powder C920 on page C8. Only spot gluing is required, but keep a weight on the target while drying/ curing.


All models have full digital equipment control, with easy to read LCD display and menu driven operation

Turbo versus diffusion pumped coating systems
High vacuum sputter coaters and vacuum evaporators commonly use an oil diffusion pump or a turbomolecular pump, both are backed by a two-stage rotary vane pump. A turbo pumped system should not be compared with a diffusion pumped system. Turbos are more expensive to purchase, but they require virtually no maintenance, don't allow oil vapour from the backing pump into the working chamber, use much less electric power and require no cooling water. Diffusion pumped systems should be phased out - why would anybody purchase a new one?

CARBON EVAPORATION
The use of carbon films on TEM specimen grids or as carbon coatings is common in electron microscopy. These films add little to the background signal and they have relatively good electrical conductivity. Thin films (5 nanometres) are used in TEM to stabilise some specimens. Thicker films (up to 30 nanometres) may be used for TEM support films and in SEM for X-Ray microanalysis. Commonly, a high vacuum evaporator with carbon rods is used to produce these coatings and this system is preferred for some applications. The use of carbon fibre, has allowed a flash evaporation technique, which is suitable for many general EM requirements. Quorum manufactures a range of evaporators to meet all needs. Carbon coatings produced in high vacuum have a finer grain and these are preferred for some TEM applications; flash evaporated carbon is used for conventional SEM and EDS /WDS. Carbon fibre must be used in the low vacuum, rotary vane pump only. For high vacuum system carbon/graphite rods are preferable.

PUMPS: All carbon evaporators require an appropriate size, two stage mechanical pump. Turbo pumped instruments include the turbo pump, but require a mechanical pump to back the turbo pump. ProSciTech supplies pumps for these instruments or as separate pumps for other equipment quite competitively. Inquire for more information.

Rotating and more complex Specimen Stages

Rotation of specimens during evaporation or sputtering increases uniformity of coatings and this is often a desirable feature, even with flat specimens.

Most Emitech coaters are supplied with a rotating stage, which also allows setting the angle of tilt prior to evacuation. For Emitech instruments there is a choice of several more complex stages as optional extras

Stage Type
Suited to these models:
  • Heated Stage (Fixed Stage) - K575X, K575d, K950X
  • Rotate/Oscillate Stage - K550X, K575X, K650X, K675X, K950X
  • Rotate/Tilt Stage - K650X, K675X
  • Rotating Stage, Planetary, Ext. Tilt - K975X
  • Standard Planetary Stage (fixed angle 45 degree) - K950X, K550X
  • Variable Speed, Planetary Stage with External Tilt - K950X

As an example, here are the features of the Standard Planetary Stage (fixed angle 45 degrees). This stage was developed for the K950X, but customers with severe coating problems discovered they could use in the K550X and Emitech have adapted it for that use.

The stage holds 6 samples, with the tilt fixed at about approx 45 degrees. During coating, the samples rotate in relation to the central axis.

Each planet is bored to hold 3.2mm pin mounts, 1/4 inch pin mount and 15mm diameter mounts.

The K950X and K550X readily accept this stage.
