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 method wherein a substrate is subjected to one or more volatile precursors, which respond and/or decompose to the substrate surface area to supply the desired slender movie.
Measures within the CVD Approach:
Precursor introduction
Chemical reaction and movie development
By-solution removal
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling usually utilised outside America, notably in British English. Despite the spelling variation, it refers to the similar large-precision coating process.
