A method of reducing micropipes in thin films by using sublimation growth
The micropipe termination by using a W or Pt thin film was demonstrated. A SiC single crystal was grown on the modified-Lely seed with W or Pt mask, by the sublimation method. The optical micrograph made it clear that a micropipe contained in seed crystal was terminated at the metal deposited interface. The effect of metal mask thickness on the termination efficiency was also studied.
