Contamination by foreign particles
High-purity graphite grades reduce the risk of process contamination to a minimum. Through targeted selection of the starting material and appropriate post-cleaning as well as cutting-edge manufacturing processes, we ensure that your components function consistently even under extreme conditions.
Long delivery times for special components
We support your R&D department with fast, flexible manufacturing processes — including prototype production and rapid series adjustment. Thanks to our modern machinery and scalable production management, we deliver in the shortest possible time, even with complex requirements.
Supply bottlenecks and quality issues
CTG-Graphite stands for long-term reliability. With certified quality assurance in accordance with DIN EN ISO 9001, strict incoming and final inspection and clear traceability, we ensure that your components always meet the desired specifications — reproducible at any time.
Applications for graphite in semiconductor production
CTG-Graphite manufactures precise graphite components for key components in semiconductor production. Our products are used wherever thermal, chemical and mechanical resistance is required — while maintaining the highest requirements for purity and dimensional accuracy.
Our portfolio includes the following components:
stoker
For uniform temperature distributions in high-temperature processes such as CVD, PVD or epitaxy. Graphite offers excellent thermal conductivity combined with high temperature stability.
electrodes
For current transfer in plasma processes or ion implantation. Graphite offers good electrical conductivity and corrosion resistance.
isolation
Thermal insulation elements for process chambers — often as layer carriers or molded parts to minimize energy losses and ensure precise temperature profiles.
heat shields
Protection components in high-temperature environments that protect sensitive components from direct exposure to heat.
Susceptors
Support structures for substrates (e.g. wafers), which ensure uniform heating during the furnace process. Graphite acceptors are particularly dimensionally stable and temperature-resistant.
ion implanter components
Specialized components for semiconductor doping systems. Here, dimensional accuracy is crucial to ensure the exact control of the ion beam.
gas distributor
For the precise introduction of process gases into reaction chambers — e.g. in CVD processes. Graphite offers high chemical resistance and temperature resistance.
Such components are manufactured individually to your specifications — with high-purity graphite, documented traceability and certified quality assurance.
