Morgan Advanced Ceramics Performance SiC CVD SiC chemical vapor desposition Silicon Carbide
Categories: Ceramic; Carbide

Material Notes: Ultra Pure SiC (Silicon Carbide) is made via a chemical vapour deposition (CVD) process, a method that produces very uniform material. The combination of excellent thermal, electrical and chemical properties makes CVD SiC well suited to many semiconductor, LED, and optical applications.

Features:

  • Ultra-pure 99.9995% (by GDMS)
  • High thermal conductivity
  • Low thermal expansion
  • Excellent corrosion resistance in plasma applications
  • Proven durability in high temperature ammonia environments
  • Dimensional stability
  • Non-porous, theoretically dense
  • Fine grained microstructure
Two Grades Available:
  • Performance HR SiC – (high resistivity)
  • Performance ELR SiC – (extremely low resistivity)
Typical Applications:
  • Rapid Thermal Process (RTP) components
  • Plasma Etch components
  • Susceptors and Heating elements
  • LED wafer carriers and cover plates
  • Sputtering Targets
Morgan Capabilities:
  • High volume growth capacity
  • Patented RMax Process (near-net shape process for high volume ring applications)
  • CNC grinding and lapping to very tight tolerances
  • Prototype, batch and volume production
  • EDM and Ultrasonic machining option available
