What is magnetron sputtering deposition?

Magnetron sputtering is a high-rate vacuum coating technique that allows the deposition of many types of materials, including metals and ceramics, onto as many types of substrate materials by the use of a specially formed magnetic field applied to a diode sputtering target.

What is the working principle of sputtering?

The principle of Sputtering is to use the energy of a plasma (partially ionized gas) on the surface of a target (cathode), to pull the atoms of the material one by one and deposit them on the substrate.

What is the principle working of RF magnetron sputtering process?

As with DC Sputtering, RF Sputtering runs an energetic wave through an inert gas in a vacuum chamber which becomes ionized. The target material or cathode which is to become the thin film coating is bombarded by these high energy ions sputtering off atoms as a fine spray covering the substrate to be coated.

What is thin film sputtering?

Sputtering is a PVD (Physical Vapour Deposition) class of thin film technology. The material to be coated (the sputtering target) is bombarded with plasma ions and the removed particles enter into the gas phase. The vapour then condenses on the substrate surface, adheres to it firmly, and forms a very thin layer.

What are the types of sputtering?

Several types of sputtering processes exist, including: ion beam, diode, and magnetron sputtering. Angstrom Sciences specializes in Magnetron Sputtering Technology. In a magnetron sputtering application, the high voltage is delivered across a low pressure gas (usually argon) in order to create high-energy plasma.

What is the difference between RF and DC magnetron sputtering?

The main difference is that the power used in RF sputtering is AC, while that in DC sputtering is DC. Basically, during DC sputtering, the working gas will be ionized.

What is the RF frequency used for sputtering process?

Using power delivered at radio frequencies (RF) – typically at 13.56 MHz – and an automatic impedance matching network, the total impedance of the circuit can be regulated to 50 Ω which is suitable for plasma ignition in typical sputtering environments.

What’s spatter mean?

: to spurt forth in scattered drops blood spattering everywhere. transitive verb. 1 : to splash with or as if with a liquid also : to soil in this way his coat was spattered with mud. 2 : to scatter by or as if by splashing spatter water.

What means Frizzle?

Frizzle definition To form into small, tight curls; frizz; crimp. verb. A small, tight curl. noun. To fry something until crisp and curled.
