Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is a system whereby a substrate is exposed to one or more risky precursors, which react and/or decompose around the substrate surface to generate the specified slender film.
Steps in the CVD System:
Precursor introduction
Chemical response and film development
By-merchandise removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling generally used exterior The us, particularly in British English. Regardless of the spelling variation, it refers to the exact high-precision coating course of action.
