Frequent Resources Deposited:
Silicon carbide (SiC)
Silicon dioxide (SiO₂)
Titanium nitride (TiN)
Diamond
3. 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 on the substrate area to make the desired thin movie.
Measures inside the CVD Procedure:
Precursor introduction
Chemical response and film formation
By-item removing
4. CVD Chemical Vapour Deposition
CVD Chemical Vapour Deposition is an additional spelling typically used exterior the United States, specially in British English. Despite the spelling variation, it refers to the exact substantial-precision coating approach.
