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 a number of volatile precursors, which respond and/or decompose to the substrate floor to supply the desired slender movie.
Actions within the CVD Process:
Precursor introduction
Chemical reaction and movie formation
By-product elimination
four. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling commonly used outside the house The usa, especially in British English. Regardless of the spelling variation, it refers to the exact same high-precision coating system.
