What is thin movies?
spraying thin film is a process in which a thin film is applied to the surface by knocking particles from a separate target source. The process is generally carried out in a low -pressure chamber into which gaseous plasma is drawn. Positively charged ions in this plasma knock particle without target source in a process known as spraying. These particles then travel to the surface of the recipient, known as a substrate where they are stored in a thin film.
The two main methods of thin film are direct current (DC) spraying and spraying frequency (RF). When spraying DC, direct current positively charges plasma, while RF spraying uses radio waves to charge it. Positively charged plasma accelerates into a negatively charged target and releases particles of the target material that puts on the substrate. DC spraying is limited to use for conductive materials that can accommodate electricity, while RF spraying is also suitable for insulating materials.
When they are released from the target materIla, particles move in a straight line until they get into contact with something. Some of these particles are stored on the surface that needs to be covered. Passengers in other directions can instead be placed on the walls of the chamber or on other surfaces inside the chamber.
Argon gas is usually a plasma material used to vibrate particles without target material, but sometimes other inert gases such as neon or crypton are used. Accelerated plasma can knock particles without this target material in the form of individual atoms, groups of atoms or as molecules. Numerous types of spray materials are available for use in various applications. Think on a thin film can be used to store metal or non -metallic films on substrates made of metal, glass or other materialus.
common applications using thin films spraying include coating of optical tools such as mirrorAdla telescope and consumption coating such as compact discs and digital video discs. Electronic semiconductor devices and photovoltaic panels are also produced with this technology. The use of thin films has even spread to the production of drugs that are administered to the patient in the form of a thin film.
There are many advantages for using this method. Spraying thin films is relatively fast compared to other similar processes. It also allows good control of the thickness of the seated film. In addition, the target materials may not be heated as in evaporation processes, so they can be kept at low temperature if necessary.
