Popular Products Deposited:
Silicon carbide (SiC)
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 volatile precursors, which respond and/or decompose to the substrate surface area to supply 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 America, notably in British English. Despite the spelling variation, it refers back to the exact same superior-precision coating approach.
