Sputter deposition. Sputter deposition is a physical vapor deposition method of thin film deposition in which a high-purity source material (called a cathode or target) is subjected to a gas plasma (typically argon ). The energetic atoms in this gas plasma collide with the target material and knock off source atoms which then travel to …

Introduction. The so-called magnetron sputtering technique has been used as a coating method since as early as around the 1970s. Long before the physics of the sputtering process was really known, it was called "cathode sputtering," "Kathodenzerstäubung" (German), or "pulvèrisation de cathodique" (French).
Substrates were first sputter-cleaned for 10 min using an Ar ion beam generated by an anode layer ion source with a bias voltage of −600 V. After that, a pure Ti buffer layer with a thickness about 300 nm was deposited on the substrate by DCMS (DC 4020, Huettinger) at 4 kW (~485 V and ~9 A) and −100 V bias voltage for 20 min.
DC (Direct Current) Sputtering is a Thin Film Physical Vapor Deposition (PVD) Coating technique where a target material to be used as the coating is bombarded with ionized gas molecules causing atoms to be "Sputtered" off into the plasma. These vaporized atoms are then deposited and condense as a thin film on the substrate to be …
Magnetron sputtering deposition is a fast technique for applying a thin layer of inorganic materials on a substrate, such as ITO or metallic contacts. The magnetron ionizes argon gas which then accelerates towards the cathode where the target materials is located. The stream of argon ions erodes away the target material making a charged cloud ...

DC Glow Discharge Sputtering; Magnetron Sputtering; Sputtering is an etching process. The source (known as the target) is bombarded with a high energy species, leading to the ejection of a vapour flux. Sputter deposition therefore uses this flux as the vapour source for film growth. It principally consists of atoms, with a range of …
A 3-D model for the deposition rate in a sputtering system is developed. It compares well with experiments given the dc magnetron sputtering system used for the study.

A decrease of deposition rate with a decrease of the magnetic field strength is seen for the deposition of Ti in DC and pulsed DC magnetron sputtering [49]. The difference of deposition rate at constant power for HiPIMS and DC magnetron sputtering can be partly related to higher discharge voltage in HiPIMS as reported in Ref. [26]. 3.2.
