Substrate for diamond growth

Substrate or Seed for Growing single crystal diamond

Plates of various size

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

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
