Slurry for the stock polishing SiC wafer 
dvantage: 
 1. High removal rate (>2.5μm/h) 
2. Good surface quality: smooth, no obvious scratch. 
3. Long life. 
  
Application: High-purity semi-insulator 4H-SiC, N-type 4H-SiC wafer polishing, etc. 
  
Slurry for the final polishing of SiC wafer 
Advantage: 
 1. Good surface quality: surface roughness (Ra) <0.15nm.  
2. High removal rate (>1m/h).
  
3. Easy to be cleaned. 
 Application: High-purity semi-insulator 4H-SiC, N-type 4H-SiC wafer fine polishing, etc.
