Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high-quality, and high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films .
When the vapor source is a liquid or solid, the process is called physical vapor deposition (PVD), [3] which is used in semiconductor devices, thin-film solar panels, and glass coatings. [4] When the source is a chemical vapor precursor, the process is called chemical vapor deposition (CVD).
In the metal organic chemical vapor deposition (MOCVD) technique, reactant gases are combined at elevated temperatures in the reactor to cause a chemical interaction, resulting in the deposition of materials on the substrate. A reactor is a chamber made of a material that does not react with the chemicals being used.
The laser ablation method yields around 70% and produces primarily single-walled carbon nanotubes with a controllable diameter determined by the reaction temperature. However, it is more expensive than either arc discharge or chemical vapor deposition. [4]

In chemistry, a precursor is a compound that contributes in a chemical reaction and produces another compound, or a chemical substance that gives rise to another more significant chemical product. Since several years metal-organic compounds are widely used as molecular precursors for the chemical vapor deposition process (MOCVD).
Laser chemical vapor deposition (LCVD) is a chemical process used to produce high purity, high performance films, fibers, and mechanical hardware (MEMS).It is a form of chemical vapor deposition in which a laser beam is used to locally heat the semiconductor substrate, causing the vapor deposition chemical reaction to proceed faster at that site.

They also used CFD-ACE+ to model transparent conductive oxide (TCO) thin film deposition with ultrasonic spray chemical vapor deposition (CVD). [3] The University of Louisville and the Oak Ridge National Laboratory used CFD-ACE+ to develop the yttria-stabilized zirconia CVD process for application of thermal barrier coatings for fossil energy ...
