Substrate or Seed for Growing single crystal diamond
Plates of various size
Variation of substrate size is from1ｘ1mm to 25ｘ25mm.
Regular orientation is (100) with few degree off angel and (111)and (110)orientation are commercialized with limitation of size.
Roughness of polished surface
One face or both face can be polished mechanically. Regular polished surface roughness is less than 5nm. Finer surface such as Ra<2nm is possible by precise polishing even on the large area.
Both face polishing can be supplied for the thicker substrate than 0.2mm.
Toward large wafer for device fabrication
World first 1 inch wafer
Nearly 10x10mm mono crystals jointed as mosaic crystal . There can be seen visible boundaries but mostly invisible. The largest size is 28x28mm and both face can be polished.
Please require size and thickness when you place order.
