1. What is sputtering deposition?

Sputter deposition is a method of depositing thin films by sputtering material from a “target”. Sputtering is a term used to describe the mechanism in which atoms are ejected from the surface of a material when that surface is stuck by sufficiency energetic ions generated by low-pressure gas plasma, usually an argon plasma. The sputtering takes place at a much lower temperature than evaporation. Sputtered atoms ejected into the gas phase in vapor form are not in their thermodynamic equilibrium state and tend to condense on all surfaces in the vacuum chamber including the substrate.

2. Why are thin films important?

There are many useful applications for thin films. We desire to produce properties in a material that are often conflicting in nature if we use one homogeneous material. Semiconductor devices, for example, are fabricated on a thin layer deposited on a semiconductor substrate. The integrated electronic circuits depend on the confinement of electrical charges, which relies on the interfaces between different materials with different electronic properties. There are also many occasions when the properties demanded an engineering application involve features that are different for the surface than that are for the bulk. Depositing metal films and patterning them on the surface are relatively easy to secure electrical connection between semiconductor devices.

3.How does a sputtering system work?

Generally, in sputtering systems ions are generated and directed at a target, then ions sputter targets atoms. The ejected atoms are transported to the substrate and atoms condense and form a thin film. Below image shows the simple schematic of a sputtering system.

Nanostructured Coatings Company as a designer and manufacturer of vacuum coating systems will participate in the China International Import Exhibition (CIIE) 2020. The products of Nanostructured Coatings Company include Vacuum Coating Systems which coat the samples by physical vapor deposition(PVD) methods. These devices using sputtering, thermal evaporation, pulsed laser deposition(PLD) and resistive carbon fiber or carbon rod deposition, can create nanometer-thick thin films on different substrate. Small foot print, easy to operate and high precision process make efficient products suitable for research laboratories and academic centers. The deposited thin films have many applications in microelectronics, solar energy, nano, electron microscopy and etc. See more details about our products.

CIIE is held annually in China and its goal is to liberalize trade, globalize the economy and actively open the Chinese market to the world. As the first national import exhibition in the world, this exhibition provides an opportunity for companies to showcase their products and find new business partners in the world’s second largest economy. Top companies and business leaders around the world have shown great interest in attending the China International Import Exhibition in Shanghai.

The 3rd China International Import Exhibition will be held from November 5 to 10, 2020 in Shanghai. The first and second CIIE Exhibition were held in 2018 and 2019 under the auspices of the Ministry of Commerce of China and Shanghai Municipality in Shanghai, with $52 and $73 billion in trade, respectively, each year and NSC Company at China International Import Expo will participate as a producer of vacuum coating system.

You can see the products of Nanostructured Coatings Company in the National Pavilion of Iran, at the CIIE Exhibition. For more information about this exhibition, visit its website. Furthermore, you can see NSC products here.
