What is a thin film deposition?

thin films deposition is a technique used in the industry to apply a thin coating to a specific structural part made of target material and to fill its surface with certain properties. Thin film coatings are applied to a change in the optical properties of glass, corrosive properties of metals and electrical properties of semiconductors. Several deposition techniques are used, usually to add atoms or molecules, one layer at a time, to a large number of materials that lack the basic surface properties that thin coatings provide. Any design for which the coating of minimum volume and weight is required can benefit from a thin film deposition that exposes the target material for the energy, gas or plasma. The 16th century was developed by more refined techniques by the Venetian hiders. It was only in the 18th century that the accuracy of the application of thin coatings, such as electricaling and vacuum deposition, carried out the methods of accuracy.

Electropping is a form of chemical deposition, in which the part to be coated is connected to the electrode and immersed in the conductive solution of metal ions. As the current passes through the solution, the ions are attracted to the surface of the parts that slowly create a thin layer of metal. Semisolid solutions called Sol-Gels are another means of chemical storage of thin films. As long as the coating particles are small enough, the gel remains long enough to arrange into the layers and provide a even coating when the liquid fraction is removed in the drying phase.

PAR deposition is a technique to create a thin film deposition in which part is covered in power gas or plasma, usually in a partial vacuum. In the vacuum chamber, the atoms and molecules spread evenly and the crejedl coating of consistent purity and thickness. On the other hand, with a chemical deposition, the part is placed in the reaction chamber occupied by a coating in a gaseous form. PlYN reacts with the target material and creates the desired coating thickness. When plasma is stored, the coating gas is overheated into an ion mold, which then reacts with the atomic surface of the part, usually at increased pressures.

In the deposition of spraying, the source of pure coating in a solid form is under heat or electron bombing. Some atoms of a solid source are released and are evenly suspended around the surface of the part in the inert gas such as Argon. This type of thin film deposition is useful in watching fine elements on small parts that are covered with gold and observed by an electron microscope. In the case of a part for later study, gold atoms are released from a solid source above the part and fall on its surface through the chamber filled with Argonemplany.

The application of thin films deposition is diverse and expanded. Optical coatings on the lenses and glass of the board can improve the properties of transmission, refraction and reflection, produce ultraviolet (UV) filters in glassesprescription and anti -reflective glass for framed photographs. The semiconductor industry uses thin coatings to ensure improved conductivity or insulation for materials such as silicon wafers. Ceramic thin films are anticorrosive, hard and insulating; Although fragile at low temperatures have been successfully used in sensors, integrated circuits and more complex designs. Thin movies can be stored to form ultra small "intelligent" structures such as batteries, solar cells, drug supply systems and even quantum computers.
