The Quorum Q300T D-Plus is suitable for multi-layer sequential sputtering of two materials, the Q300T D Plus has two independent sputtering heads, which allows sequential sputtering of two metals without the need to break the vacuum. The system is fully automated with user defined recipes controlling the pumping sequence, time, number of sputter cycles, and the current used during the process. Unlimited layers of varying thickness from two target materials can be sputtered sequentially by cycling between both targets. When not in use the targets are shuttered for protection from contamination.

Substrates can be coated using non-oxidising (noble) metals such as gold (Au) and platinum (Pt). For coatings with a fine grain structure iridium (Ir) can also be used. With the high-quality vacuum system, the Q300T D Plus is also capable of using oxidising metal targets such as chromium (Cr) and aluminium (Al) to produce fine films and coatings. The Q300T D Plus comes as standard with a chromium (Cr) target and gold (Au) target
Recommended applications for the Q300T D Plus:
- Ideal for multi-layer coating
- Adhesion studies
These products are for Research Use Only.

• User interface software has been extensively revised, using a modern smartphone-style interface
• Comprehensive context-sensitive help
• USB interface allows easy software updates and backing up/copying of recipe files to a USB stick
• Process log files can be exported via USB port in .csv format for analysis in Excel or similar. Log files include date, time and process parameters.
• 16GB of flash memory can store more than
1000 recipes
• Quick and easy creation of process sequences with a simple copy, drag and drop operation
Allows multiple users to input and store coating recipes. New feature to sort recipes per user according to recent use.
The system prompts the user to confirm the target material and it then automatically selects the appropriate parameters for that material
Intuitive software allows the most inexperienced or occasional operator to rapidly enter and store their process data. For convenience, several typical sputtering and carbon coating profiles are already stored but also allow the user to create their own.
The software detects failure to achieve vacuum in a set period and shuts down the process in case of a vacuum leak, which ensures pump protection from overheating.
Detachable chamber with built-in implosion guard
A removable glass chamber and easily accessible base and top plate allow for an easy cleaning process. Users can rapidly change the chamber, if necessary, to avoid cross-contamination of sensitive samples. A tall chamber option is available for improved uniformity for sputtering and to hold larger substrates.
Dual head sputtering – for sequential sputtering
The Q300T D Plus has two independent sputtering heads to allow sequential sputtering of two different metals without the need to ‘break’ vacuum, for example, a thin ‘seeding’ layer of chromium (Cr) followed by deposition of gold (Au). An automatic shutter mechanism enables the cleaning of oxidising sputter targets and protects the second target and substrate during coatings. For single metal applications, one target can be selected.
Multiple stage options
The Q300T D has substrate stages to meet most requirements. All are easy-change, drop-in style (no screws) and are height adjustable (except the rotary planetary stage). A swinging arm stage drive is supplied as standard, which is a stage drive and positioning mechanism that positions the stage under the correct target. Rotation speed is variable between 14-38 rpm:
In addition, a flat, adjustable stage capable of accepting 4” (101.6 mm) wafers is supplied as standard with the Q300T D Plus.
As an accessory, a 6” wafer stage is available, which is a flat adjustable stage capable of accepting 6” or 150 mm wafers. The stage includes two masks for improving the uniformity of the coating.
Rotation stage – 50 mm Ø. This stage only rotates and has no tilt or height adjustment.
Rotate-tilt stage – 50 mm Ø. With height adjustment (target to stage height variable between 30-80 mm). The tilt angle can be pre-set (horizontal to 30°).
Rotation stage for glass slides – 25mm x 76mm
Safety
The Q300T D Plus meets key industry CE standards
• All electronic components are protected by covers
• Implosion guard prevents user injury in the event of chamber failure
• Vacuum interlocks remove power from deposition sources to prevent user exposure to high voltage in the event of the chamber being opened
• Overheating protection shuts down the power supply
Vacuum control
High vacuum turbo pumping allows sputtering of a wide range of oxidising and non-oxidising metals for thin film and electron microscopy applications. Automatic vacuum control can be pre-programmed to suit the process and material, therefore removing the need for manual intervention or control.
Cool magnetron sputtering
Sputter coating is a technique widely used in various applications; it is possible to create plasma and sputter metals with high voltage, poor vacuum and no automation. However, this is not suitable for some applications because it can heat the substrate and result in damage when the plasma interacts with the substrate. The Q series uses low-temperature enhanced plasma magnetrons optimised for the turbomolecular pump pressures, combined with low current and deposition control, which ensures your substrate is protected and uniformly coated.
The Q300T D Plus uses easy-change, 57 mm diameter, disc-style targets which are designed to sputter oxidising and noble metals. It is fitted with gold (Au) and chromium (Cr) sputter targets as standard.
Pulsed cleaning for aluminium sputtering
Aluminium (Al) rapidly forms an oxide layer which can be difficult to remove. The Q300T D Plus has a special recipe for aluminium that reduces the oxide removal time and prevents excessive pre-sputtering of the target.
Film thickness monitor
The Q300T D Plus can be fitted with an optional dual film thickness monitor (FTM), which measures the coating thickness on two quartz crystal monitors located within the chamber. The thickness measured on the monitor can be correlated to the thickness on the substrate using a mathematical formula built into the software; this allows the user to control the thickness of material deposited onto the substrate. For example, the Q300T D Plus can automatically terminate a coating profile when the required thickness has been achieved. Alternatively, the process can be terminated by time.
