Graphite for Compound Semiconductor and LED

Contact 0

Light-emitting diodes illuminate our everyday life in all colors, and are also efficient and energy saving. The light of a LED is generated in semiconductor connections. Their performance depends crucially on the quality of these semiconductors.

This is where our specialty graphite comes into play: isostatic graphite is fundamental for the production of compound semiconductor layers.These are generated in the “hot zone“ under extreme temperatures during the so-called epitaxy, or MOCVD process. The rotating carrier on which the wafers are coated in the reactor, consists of silicon carbide-coated isostatic graphite. Only this very pure, homogeneous graphite meets the high requirements in the coating process.

Semiconductor

High-purity graphite components are crucial to processes in the semiconductor, LED and solar industry. Our offering ranges from graphite consumables for crystal growing hot zones (heaters, crucible susceptors, insulation), to high-precision graphite components for wafer processing equipment, such as silicon carbide coated graphite susceptors for Epitaxy or MOCVD.
