The EMS150R is a compact rotary-pumped coating system suitable for SEM sputtering with non-oxidizing (noble) metals – e.g. gold (Au), gold/palladium (Au/Pd) and platinum (Pt) – and for carbon coating SEM specimens for EDS and WDS.

The EMS150R is available in three formats: sputtering (EMS150R S), carbon fiber coating (EMS150R E) and a combined sputtering and carbon fiber coating system (EMS150R ES).

Key Features

  • Metal sputtering or carbon coating, or both – in one space saving format
  • Rotary-Pumped sputter coating – allows sputtering of a range of non-oxidizing (noble) metals (e.g. Au, Pt, Ag and Pd)
  • Carbon fiber coating – ideal for SEM carbon coating applications (EDS and WDS)
  • Controlled pulse carbon cord evaporation – precise control, reduced carbon debris
  • 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)
  • Three-year warranty

Product Description

Ideal for W-SEM sputtering and carbon coating applications

The EMS150R is a Rotary-Pumped coater available in three formats: sputtering, carbon evaporation or both. Depending upon the selected configuration, the EMS150R can be a sputter coater for scanning electron microscopy (SEM), a carbon coater suitable for SEM (e.g. EDS and WDS), or both in a single, easy-to-use system.

Note: For field emission (FE) SEM and for TEM-quality carbon coating, please use the turbo-molecular pumped EMS150T.

Molded case with color touch-screen

The EMS150R is presented in a custom-molded, one-piece case which allows easy access for servicing. The embedded, color touch screen allows multiple users to input and store coating 'recipes'. The case houses all the working components, including an automatic bleed control that ensures optimum vacuum conditions during sputtering.

The vacuum chamber has an internal diameter of 150 mm/6" and comes with an integral implosion (safety) guard.

A variable-speed rotary specimen stage is fitted as standard, with other stages available as options. For further details, see Additional Information.

Sputter coating, carbon coating – or both

The EMS150R is available in three formats, each with a range of optional accessories:

  • EMS150R S – A rotary-pumped sputter coater for non-oxidizing (noble) metals. A gold (Au) target is fitted as standard, with other metals – such as gold/palladium (Au/Pd) and platinum (Pt) – available as options.
  • EMS150R E – A compact rotary-pumped carbon fiber coater, suitable for W-SEM EDS and WDS applications. Fitted as standard with a carbon fiber evaporation head insert, an optional carbon rod insert is also available.
  • EMS150R ES – A combined system with both sputtering and carbon coating. The deposition inserts can be swapped in seconds and the intelligent system logic automatically detects which insert is in place and displays the appropriate operating settings and controls for that process.

All models can be fitted with a range of optional accessories (a carbon rod coating insert, film thickness monitor, glow discharge, etc.). See Additional Information for more details.

Platinium sputtering

Please note that for sputtering platinium (Pt), the optional Pt coating vacuum hose assembly is required.

Controlled pulse carbon cord evaporation

Installed as standard on E and ES models, controlled profiles ensure carbon is evaporated in short pulses. This significantly reduces or eliminates the amount of debris (large carbon fragments) associated with traditional carbon "flash" evaporation. Plus it allows carbon cord evaporation to be accurately controlled using the optional film thickness monitor (FTM) accessory.

Rapid data entry

At the operational heart of EMS150R is a simple color touch screen, which allows the most inexperienced or occasional operators to rapidly enter and store their own process data. For convenience, a number of typical sputtering and carbon coating profiles are already stored.

Maintenance

The intuitive touch screen interface features maintenance prompts which highlights time of the last clean, coating time since last clean, system 'on time', and time of the last service.

Pumping requirement

A suitable rotary vacuum pump is required. The Pfeiffer DUO 6 5m3/hr two-stage rotary vacuum pump (91003) is ideal for this purpose. See Ordering Information for more details.

Options and Accessories

The EMS150R has an extensive range of options and accessories, including a glow discharge insert, film thickness monitor (FTM) and specimens stages to suit most applications. For details, see Additional Information.

Glow Discharge Attachment

The primary application of glow discharge is as a technique for the surface modification (wetting) of newly evaporated transmission electron microscopy (TEM) carbon support films.

Hydrophilization

Freshly-made TEM carbon support films tend to have hydrophobic surfaces which inhibits the spreading of suspensions of particles in negative staining solutions. However, after glow discharge treatment with air, the carbon film is made hydrophilic and negatively charged, allowing easy spreading of aqueous suspensions.

With subsequent magnesium acetate treatment, the surface is made hydrophilic and positively charged. In addition to glow discharge treatment using air, other process gases may be used to modify surface properties. For example, methanol as a process gas results in the surface becoming hydrophobic and negatively charged. Such treatment can facilitate the optional absorption of selected biomolecules.

Coating head options

A range of interchangeable, plug-in style coating head inserts are available:

Sputtering head insert. Suitable for oxidizing (noble) metals. Supplied with a 57 mm Ø x 0.1 mm thick gold (Au) target as standard. For additional targets, see Ordering Information.

Additional sputter head insert. Available for quick coating material change (RS and RES versions only).

Carbon rod evaporation head insert (for 3.05 mm Ø rods).

Carbon fiber evaporation head insert.

Specimen stages

The EMS150R has specimen stages to meet most requirements. All are easy-to-change, drop-in style (no screws) and are height adjustable (except for the rotary planetary stage):

Rotation stage. 50 mm Ø (fitted as standard). This stage only rotates – no tilt or height adjustment.

Rotate-tilt stage. 50 mm Ø with height adjustment (target-to-stage height variable between 37 mm and 60 mm). The tilt angle can be preset.

Variable angle rotary planetary stage with 50 mm Ø specimen platform.

Large flat rotation stage for 4"/100 mm wafers.

Rotation stage for glass microscope slides.

Other options

Extended height chamber for tall specimens – for use with tall specimens and with Rotacota stage.

Film Thickness Monitor (FTM). The optional 4517 consists of a controller and quartz crystal oscillator built into the EMS150R, and a vacuum feed through, chamber-mounted crystal holder and quartz crystal. As sputtered or evaporated material is deposited onto the crystal, its frequency of oscillation is modified. This modification is used to measure and control the thickness of metal film.
