Introducing Acktar Core Black™
The ultimate ultra-black coating for wafer chucks and mounting applications
In a world where precision, abrasion resistance and cleanliness can mean the difference between success and failure, Acktar Core Black™ sets a new standard in the world of high-performance coatings. Developed for wafer chucks and component mounting for demanding applications in the semiconductor, optics, aerospace and laser technology, this black coating offers an exceptional combination of performance, reliability and purity.
Key features that make the difference
Specifically for wafer chucks in the semiconductor industry
The Acktar Core Black™ variant has been specially developed for use on wafer chucks and offers high abrasion resistance to withstand mechanical wear and frequent handling.
Maximum flatness & durability
With a surface flatness of 2–3 micrometers and exceptional durability, the coating also offers maximum mechanical reliability.
Wide wavelength range
Whether VIS or IR this coating works across an extremely wide spectrum, making it highly versatile for a wide range of applications.
Acktar Core Black™ absorbs up to 97.5% of light – meaning low stray light reflections with a high abrasion coating.
Diffusive & noise-free
The surface is deliberately designed to be diffusible: it eliminates ghost images and ensures an almost noise-free background – a must for precise measurements and imaging techniques.
Thermally stable
Whether it’s extremely cold (4 K) or extremely hot (up to 723 K), Acktar Core Black™ remains steadfast and reliable. Perfect for cryogenic environments and high-temperature applications.
Ultra-clean & particle-free
With values such up to MOC ~ 1 ng/cm² and PAC < 30 ppm, this coating meets the strictest cleanliness standards – perfect for clean rooms in semiconductor and optical manufacturing.
ESD protection included
Thanks to its dissipative properties, Acktar Core Black™ is ESD-safe and reliably protects your sensitive electronic components from electrostatic discharge.
Technical data at a glance:
- Layer thickness: <5 μm
