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.
