Semiconductor Applications

Epitaxy is one of the key processes in modern semiconductor processing. With CVD SiC coated graphite solutions our customers benefit from a wide range of advantages:

  • high performance due to long life and state of the art manufacturing processes
  • outstanding uniformity due to proprietary CVD systems and automated process controls
  • stable substrate that is able to withstand extremely volatile environments
  • stoichiometrically balanced coatings offer unparalleled performance and strength
  • highly resistant to most process chemicals including etchants and acids
LED Applications

Apart from susceptors in epitaxy applications, SiC coated graphite for use in wafer carriers are the main consumable in MOCVD reactors for LED production. With our SiC coated graphite solutions our customers benefit from several unique advantages in LED production:

  • stable substrate that is able to withstand extremely volatile environments
