Hello to everyone, I have a question about ultra-smooth ITO glass. Which company could provide ultra-smooth ITO glass, the surface roughness should be less than 1nm, thickness is about 0.5mm. This ITO glass will be used as a substrate in e-beam lithography. Polished glass and very smooth silicon are very common, and a lot of company could provide. But most companies could only provide ITO glass with very rough surface (the roughness is usually 5nm, cannot be used in e-beam lithography). If you know the company which could provide very smooth ITO glass, please let me know. Thank you very much. Best regards, xingzhan
