TACCOTA®


Efficient protection of graphite parts used in semiconductor production & processing

Efficient protection

Nippon Kornmeyer Carbon Group GmbH and Fraunhofer IISB present their innovative and patented tantalum carbide coating technology TACCOTA®.

The high temperature and corrosion resistant coating can be applied to graphite substrates and used in semiconductor material production and processing. It secures graphite parts from decomposition and corrosion in typical high temperature and reactive gas processes like SiC and nitride PVT crystal growth and epitaxy, ion implantation, and plasma processing. The benefit is an increased life time and improved cost of ownership.

TACCOTA® - improves your semiconductor material production and processing.

The new technology briefly explained

Flexible coating properties

The process technology allows the adjustment of the desired coating properties such as thickness and composition (i.e. blend with other high temperature ceramic materials).

Advanced coating


High temperature resistance (up to 3000°C)


Resistance against corrosive gases and fluids, molten metals and salts


Excellent wear resistance and good adhesion to the graphite substrate


Thickness between 20 -300 μm adjustable


Surface roughness Raof about 1-2 μm independent of coating thickness


Adjustable from porous to dense layers with different permeabilities


Variable coating composition (mixtures with other UHTC materials)

Flexiblefor part size and geometry


Partial and all-around coating possible


Part refurbishment


Resourceefficient and environmentally friendly


Use of only conflict-free materials


Industry ready
