Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is actually a method wherein a substrate is subjected to one or more volatile precursors, which respond and/or decompose about the substrate surface area to provide the specified slim film.
Steps during the CVD Course of action:
Precursor introduction
Chemical reaction and movie formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling normally utilised outside The usa, specifically in British English. Regardless of the spelling variation, it refers to the same significant-precision coating method.
five. CVD and PVD Coating
CVD and PVD coating are the two physical vapor deposition procedures utilized for implementing thin movies. Nevertheless, they vary drastically in their processes and apps.
CVD (Chemical Vapor Deposition):
