Q300R T Triple Target, Large Chamber, Rotary-Pumped Sputter Coater

The Q300R T is a large chamber, rotary-pumped coating system ideally suited for sputtering a single large diameter specimen up to 8"/200 mm (e.g. a wafer), or multiple smaller specimens over a similar diameter. 

The Q300R T is suitable for sputtering non-oxidising (noble) metals, e.g. gold (Au), gold/palladium (Au/Pd) and platinum (Pt). For oxidising metals see: Q300T T.

Key features
  • Large area sputter coating - up to 8"/200 mm diameter
  • Triple sputtering head - ensures even coating deposition of large specimens
  • Single target selection - for economic coating of small specimens
  • Sputtering of a range of non-oxidising (noble) metals - such as gold (Au), platinum (Pt) and silver (Ag). For oxidising metals see: Q300T T
  • Precise thickness control using the film thickness monitor option
  • Fully automatic touch screen control - rapid data input, simple operation
  • Easy-to-change, drop-in style specimen stages (rotation stage as standard)
  • Thick film capabilities - up to 60 minutes sputtering time without breaking vacuum
  • Extended warranty option

Ideal for sputter coating large SEM specimens

The Q300R T is suited for sputtering noble metals, such as gold (Au) and platinum (Pt) for scanning electron microscopy (SEM) and thin film applications.

The Q300R T is fitted with three individual sputtering heads to ensure even deposition of individual large specimens or multiple smaller specimens. For economical coating of small specimens ‘single target’ mode can be selected.

NB: It is not possible to sequentially sputter three different sputtering metals from each sputtering head - for sequential coating see the Q300T D Dual Target Sequential Sputtering System.

Moulded case with colour touch screen

The Q300R T is presented in a custom moulded, one-piece case, allowing easy servicing access. The embedded colour touch screen allows multiple users to input and store coating ‘recipes’. The case houses all the working components, including automatic bleed control that ensures optimum vacuum conditions during sputtering.

The vacuum chamber has an internal diameter of 283 mm/12” and comes with an integral implosion guard. The Q300R T also includes ‘vacuum shutdown’, a useful feature which enhances vacuum performance by allowing the chamber vacuum to be maintained when the system is not in use.

A variable-speed rotary specimen stage is fitted as standard and is suitable for 8"/200 mm and 6"/150 mm wafers. For other stages see: Ordering Information.

Rapid data entry 

At the operational heart of the Q300R T is a simple colour touch screen, which allows even the most inexperienced or occasional operator to rapidly enter and store their own process data. To further aid ease of use a number of typical sputtering and carbon coating profiles are already stored. For added convenience summaries of the last 100 coatings carried out can be viewed.


The touch screen interface features maintenance prompts that highlight time of last clean, coating time since last cleaned, system ‘on time’ and time of last service.

Pumping requirement

A suitable rotary vacuum pump is required. The Pfeiffer DUO 6  5 m3/hr two-stage rotary vacuum pump is ideal for this purpose. Dry pumping alternatives are also available. See: Ordering Information for more details.
