CVD is the abbreviation for Chemical Vapor Deposition, which refers to a method of depositing thin films by using chemical catalysts on the surface of a substrate film, with at least one of the reactants being in a gaseous state and at least one of the products being in a solid state. The CVD here produces solid-phase products in the form of thin films, rather than in other forms such as powders or whiskers. As a thin film process, CVD has multiple advantages, ultimately leading to it sometimes being more favored than PVD process.
Magnetron sputtering is a physical vapor deposition technique that has numerous advantages and is widely used in multiple fields.
Working principle: By introducing a magnetic field on the surface of the target cathode and using the magnetic field to constrain charged particles, the plasma density is increased, thereby increasing the sputtering rate.
For the scraping method, first place the substrate on a high-temperature platform, and then use a blade to guide the precursor solution forward, forming a wet film on the surface of the substrate. At this point, as the solvent evaporates, the solvate crystallizes on the substrate and forms a thin film. In addition, the precursor solution will diffuse after dropping onto the substrate, and the understanding of this process can be similar to the process of dropping water onto a glass plate. The first step of the scraping method is to adjust the wettability of the solution and substrate to increase its coverage on the substrate.
