Why Does Silicon Wafer Roughness (RMS) Matter?

We polish silicon wafers to create a smooth surface to generate higher yields when making semiconductor devices. Polishing turns otherwise dull rough surface to one that is very flat with mirror like quality and is free of particles.

The majority of our wafers are polished using Chemical Mechanical Polishing (CMP).
