Cressington Sputter Coater 208HRD

Cressington 208HRD High Resolution Sputter Coater from Cressington offers real solutions to the problems encountered when coating difficult samples for FESEM imaging. FESEM applications need extremely thin, fine-grained, uniform coatings to eliminate charging and to improve contrast on low density materials. In order to minimize the effects of grain size, the 208HR offers a full range of coating materials and gives unprecedented control over thickness and deposition conditions. The 208HRD Turbo Pumped High Vacuum System offers a wide range of operating pressures allowing precise control of both uniformity and conformity of the coating, minimizing charging effects.

The 208HRD employs a compact 28mm diameter target design that offers higher efficiency to better utilize more expensive target materials such as iridium. An additional benefit with using a smaller diameter sputter source is that it helps lower the total system cost with target compared to larger target systems.

Sputter Target : Cr, Pd/Pt as standard, ( Ta, Au, Au/Pd, Pt, Ir or W is optional )
 

The main features are:-

• Wide Choice of Coating Materials Magnetron head design and effective gas handling allow a wide choice of target materials (see specification).
• Economical target utilization. The 208HRD offers a smaller diameter target and modified chamber configurations to give more economical usage for costly materials like iridium.
• Precision Thickness Control. Thickness optimized for FESEM application using the MTM-20 High Resolution Thickness Controller, which has a resolution of 0.1nm. This enables precise and reproducible thin coatings, especially in the range of 0.5 - 3nm, a thickness desirable for FESEM applications.
• Multi-angle Stage Movements. Separate rotary, planetary and tilting stage movements ensure uniform coating with excellent conformity, even on highly topographic samples.
• Variable Chamber Geometry: Chamber geometry is used to adjust deposition rates from 1.0 nm/sec to 0.002 nm/sec to optimize structure.
• Wide Range of operating Pressures: Independent power/pressure adjustment allows operation at argon gas pressure ranges.
• Compact Modern Benchtop Design: Space and energy saving design eliminates need for floor space, water, specialized electrical connections.
