Frequent Resources Deposited:
Silicon carbide (SiC)
Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
three. Chemical Vapor Deposition CVD
Chemical Vapor Deposition (CVD) is a course of action whereby a substrate is subjected to one or more risky precursors, which react and/or decompose to the substrate floor to generate the specified skinny movie.
Techniques from the CVD Approach:
Precursor introduction
Chemical reaction and movie formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is another spelling usually applied outdoors the United States, particularly in British English. Regardless of the spelling variation, it refers to the same significant-precision coating approach.
