Compared to ALD, sputtering of oxide dielectrics might result in non-uniformity of thin films with high surface roughness a fully transparent metal oxide TFT was successfully fabricated solely through the sputtering process, involving the surface confinement of the sputtered Al 2 O 3 dielectric layer, which exhibited a low surface roughness of 1.23 nm. The
RF sputtering from a compact co-sputtering source proved to be a suitable method for depositing thin dielectric films. This type of apparatus can be set up to add dopants to a material such as barium titanate, thereby allowing convenient investigation of their effect on the relative permittivity and other electrical properties.

Sputtering is an effective technique for producing ultrathin films with diverse applications. The review begins by providing an in-depth overview of the background, introducing the early development of sputtering and its principles.
We discuss established methods of making sputter processes directional, examples of processes using multiple layers of sputtered materials, and representative examples of sputter processing with other methods of thin-film deposition in multi-step sequences, such as chemical vapor deposition and atomic layer deposition (ALD).
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.
Recently, sputtering has become a common technique for the deposition of thin films in microfluidic and nanofluidic devices. For most applications, it is used as a convenient means for the production of patterned electrodes. However, as will be shown below, sputtering can be used to achieve far more than this.
For the scenario of films sputtered with low current (< 0.25 A), the film thickness increases rapidly with increasing sputtering current, and the strain relaxation could reduce strain energy to a greater extent than the increase in surface energy [24,25,26]. Therefore, the films tend to adopt a (111) texture to lower strain energy. Also in this stage, all films are nitrogen
Gold films deposited by direct current magnetron sputtering are used for synchrotron radiation optics.

Upon systematically adjusting the sputtering current, target-substrate distance and deposition time, the evolution of film properties were investigated in detail in terms of the composition, crystalline structure, resistivity, thickness and surface roughness.
Sputtering for Film Deposition Alexander Iles* and Nicole Pamme Department of Chemistry, The University of Hull, Hull, UK Synonyms Cathode sputtering; Impact evaporation; Physical vapor deposition Definition The verb to sputter originates from sputare (Latin, to emit saliva with noise). Sputtering is the ejection of atoms from a surface following bombardment by suitably energetic
High-k HfO 2 thin films were assessed as a gate dielectric for possible oxide thin-film transistor applications. A HfO 2 gate dielectric layer was deposited by radio frequency magnetron sputtering
Power: sputtering power plays a role in both the films deposition and the film thickness formation during the sputtering (deposition) process (Ejaz et al., 2022). Atoms sputter more often as a
The sputtering process is governed by a range of different parameters. These parameters can be manipulated to alter the properties of the deposited film. In DC sputtering systems, the maximum energy E) of the atoms ejected from the target is determined by the applied voltage.
