Challenges in diamond growth

 

  • Maintaining stable microwave plasma is difficult
  • Gas ratio (CH₄/H₂) must be tightly balanced
  • Plasma can arc or touch chamber walls, causing damage
  • Nucleation is hard on non-diamond substrates
  • Seed crystal orientation affects single-crystal growth
  • Trace impurities (O, N, Si) lead to defects
  • Risk of forming graphite or amorphous carbon
  • High microwave power requires robust reactor design
  • Reactor geometry strongly affects plasma shape and uniformity
  • Scaling up growth increases uniformity and thermal challenges
  • Substrate heating and cooling must be finely tuned
Features

  • The clamshell-style design ensures effective resonance while allowing easy access for operation and maintenance
  • Aerospace-grade aluminum alloy chamber can survive even without chill water
  • All gas connections utilize Ultra-High Purity (UHP) grade components to ensure contamination-free operation
  • The annular quartz window is isolated from direct plasma exposure, thereby preventing any risk of silicon contamination
  • The operating pressure can be raised to as high as 300 torr* to enable the formation of high-density, multimode plasma
  • High-precision mass flow controllers (MFC) are used to accurately regulate doping concentrations
  • Intuitive LabVIEW user interface on Windows, featuring enhanced cloud connectivity
  • Four symmetrical CF35 viewports on the sides, and four CF16 plus one CF35 viewport on the top, allow attachment of various characterization instruments
  • Experienced PhD teams with fast response capabilities deliver critical intangible value to drive success
  • A robust safety interlock mechanism prevents unsafe operation and protects both users and equipment

*: Other operation conditions also apply to achieve high-pressure operation.
