On an atomic level, sputtering is the process whereby atoms of a target or source material is bombarded by high energy particles in a vacuum environment that “knocks off” or “sputters” atoms that are deposited as a thin film onto a substrate – such as a silicon wafer, solar panel or optical device… Read More.

Sputtering targets are crucial in various industries that rely on thin-film technology, including electronics, optics, and energy production. The term “sputtering target” is derived from the material’s function in the sputtering process, a technique within physical vapor deposition (PVD).

2022年11月10日 · Sputtering is a process that enables the creation of film coating made of sputtered atoms. Without this method, it would be nearly impossible to attain the high-quality coating films necessary for LED displays, optical filters, precision optics, and more.

2013年10月7日 · Coating methods include Physical Vapor Deposition (PVD) and one technique is called Sputtering. The sputtering method of thin film deposition involves introducing a controlled gas, usually chemically inert argon, into a vacuum chamber, and electrically energizing a cathode to establish a self sustaining plasma.

2023年2月13日 · Radio frequency (RF) sputtering is a sputtering method that uses a high-voltage alternating current (AC) power source to supply power to the magnetron and create positively charged sputtering gas. The more traditional method of direct current (DC) sputtering uses DC power to achieve this giving the plasma slightly different properties.

Today, sputtering has grown to be the most widely used vacuum deposition technique, with applications in industry and experimental research. In industry, sputtering is used to manufacture magnetic storage disks in personal computers, and for producing optical coatings [2].

Our 'MBE' sputtering system is an eight target sputtering system modified from an old MBE. The system has an in-situ Pt heater, which can produce substrate temperatures up to 400 ºC during deposition. The system reaches an ultra-high vacuum level of 3×10 -8 Torr.

2025年2月5日 · Sputtering deposition is a method of creating thin films of a few nanometers to a few micrometers on the desired substrate. In this process, the atoms separated from the surface of the target material are gaseous. These thermodynamically unstable atoms tend to be on a surface in a vacuum chamber.

2023年7月28日 · Sputtering and etching are key processes for the fabrication of semiconductor devices. In this article, we’ve looked at what sputtering is and how it works in the semiconductor industry.

Sputtering is a physical vapor deposition (PVD) process used for depositing materials onto a substrate, by ejecting atoms from sputtering targets and condensing the ejected atoms onto a substrate in a high vacuum environment.

2025年2月5日 · What is the Sputtering Yield? Deposition of thin films of different materials by DC or RF sputtering is a known coating method widely used in the deposition of hard coatings, thin film semiconductors, solar cell fabrication, SEM sample preparation, etc.The sputtering coating efficiency is highly dependent on the sputter yield of the target material, the ratio of atoms …

While sputtering threshold energy is an absolute theoretical concept defined as the critical ion energy necessary to initiate sputtering, we have assumed a finite cut-off value for the sputtering yield of ∼ 10 − 4 atoms/ion in quantifying the sputtering threshold energy from MD. While a lower threshold energy could conceivably be obtained from yields of ∼ 10 − 5 atoms/ion or lower, it ...

2022年6月1日 · DC sputtering, or direct current sputtering, is a thin film physical vapour deposition coating technique that uses a direct current as a power source. It offers numerous advantages in metal deposition for coating.

A sputtering system is a vacuum chamber, which after it is pumped out, is re-filled with a low-pressure argon gas. A high voltage ionizes the gas, and creates what is known as the Crookes dark space near the cathode, which in our case consists of a metal target made out of the metal we want to deposit.

2025年2月6日 · Indium electrodes were formed at the four corners of the sample and connected to the terminals of the Hall effect measurement system using gold wires.
