Is it possible to get a near perfect flat surface with the roughness no more than 1-10 nm at any point?
If it is, then how difficult is it?

Gokul43201 said:What material are you working with, and what is the size of the active area that you want flat ? And what's your budget ?
Gokul43201 said:We routinely make samples that have a flatness and parallelism of less than 100nm over an area of about 10 sq. mm.
Creating a near perfect flat surface can be very difficult, as it requires precision and attention to detail. Even a slight imperfection can affect the overall flatness of the surface.
The most common methods for creating a near perfect flat surface include milling, grinding, lapping, and polishing. These methods involve removing material from the surface to achieve the desired flatness.
Some challenges that may arise include maintaining a consistent pressure and speed during the process, avoiding vibration or external forces that could affect the flatness, and ensuring the surface is free of debris or contaminants.
Yes, with the use of advanced technology and precise measurements, computers and machines can achieve a near perfect flat surface. However, human supervision and adjustments may still be necessary to ensure the best results.
Near perfect flat surfaces are crucial in industries such as semiconductor manufacturing, optics, aerospace, and precision engineering. They are also important for applications such as mirrors, lenses, and electronic components.
