Epitaxy and MOCVD
For thin film deposition phases such as epitaxy or MOCVD, Mersen supplies ultra-pure graphite equipment used to support substrates or "wafers". At the core of the process, this equipment, epitaxy susceptors or satellite platforms for the MOCVD, are first subjected to the deposition environment:
- High temperature.
- High vacuum.
- Use of aggressive gaseous precursors.
- Zero contamination, absence of peeling.
- Resistance to strong acids during cleaning operations

Ion implant
The ion implantation technique is used in the semi-conductor industry to locally modify the composition and physical properties of a substrate, especially when doping agents such as boron, phosphorus and arsenic introduced…
The electrodes and graphite protective screens on these machines are subjected to significant erosion caused by ion bombardment.
Mersen's fine grain and high-density ultra-pure graphite resists erosion very well.
Mersen has also developed a Vitreous Carbon Impregnation "VCI", to further enhance the strength of these parts, while reducing particle emissions.

Ultra-pure graphite coated with silicon carbide
Mersen proposes equipment made of ultra-pure graphite coated with silicon carbide.
These dedicated solutions are the fruit of our expertise in materials and precision machining:- Ultra-pure graphite grades checked by ETV-ICP.
- The compatibility (CTE) of our graphite grades with silicon carbide guarantees long term integrity of the protective coating.
- Our precision machining process undergoes three-dimensional examination to ensure that the design of highly complex parts is respected.
