Chrome Sputtering Target Of The Inert Gas

Haohai Metal Materials Co., Ltd. | Updated: May 10, 2017

Chrome sputtering target

1) Chrome sputtering target principle:

An orthorhombic magnetic field and an electric field are applied between the sputtering target (cathode) and the anode, and the required inert gas (usually Ar gas) is charged in the high vacuum chamber. The permanent magnet forms 250 to 350 on the surface of the target material Gaussian magnetic field, with the high voltage electric field composed of orthogonal electromagnetic field. Under the action of the electric field, Ar gas is ionized into positive ions and electrons, the target is added with a certain negative high pressure, the electrons emitted from the target are affected by the magnetic field and the ionization probability of the working gas increases, forming a high density plasma in the vicinity of the cathode Body, Ar ions in the role of Lorentz force to accelerate the flight to the target surface, at a high speed bombardment of the target surface, so that the sputtering of the target atoms follow the momentum conversion principle with a high kinetic energy from the target fly The substrate is deposited and deposited. Magnetron sputtering is generally divided into two kinds: DC sputtering and RF sputtering, DC splash device which is simple in principle, in the sputtering of metal, its rate is also fast. The use of RF sputtering is more extensive, in addition to sputtering conductive material, but also sputtering non-conductive materials, but also can be reactive sputtering preparation of oxides, nitrides and carbides and other compounds. If the frequency of the radio frequency after the microwave plasma sputtering, and now, commonly used electronic cyclotron resonance (ECR) type microwave plasma sputtering.
