Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) can be a method wherein a substrate is subjected to one or more volatile precursors, which respond and/or decompose within the substrate surface area to provide the specified slim film.
Steps during the CVD Approach:
Precursor introduction
Chemical reaction and movie formation
By-product or service removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling commonly used outside The usa, specifically in British English. Despite the spelling variation, it refers back to the exact same superior-precision coating approach.
five. CVD and PVD Coating
CVD and PVD coating are equally physical vapor deposition procedures utilized for implementing thin films. However, they vary drastically in their processes and purposes.
CVD (Chemical Vapor Deposition):
