Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) can be a approach wherein a substrate is subjected to a number of unstable precursors, which react and/or decompose over the substrate floor to create the desired slender film.
Measures within the CVD Process:
Precursor introduction
Chemical response and film development
By-merchandise removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling generally made use of exterior The us, particularly in British English. Regardless of the spelling variation, it refers to the exact substantial-precision coating procedure.
