High sputtering targetthan the traditional materials industry, general requirements, such as size, smooth degree, purity, the impurity content, density, N/O/C/S, grain size and defect control; contains higher requirements or special requirements: surface roughness, resistance value, grain size distribution, composition and microstructure, foreign body (oxide) content and size, permeability, ultra high density and ultra-fine grain and so on. Magnetron sputtering is a new physical gas phase deposition method is electronic gun system for the electron emission and focusing on the plated material to be sputtered out atoms obey the momentum transfer principle to higher energy from material toward the substrate deposition film. This is called the sputtering target material plating. Sputtering metal, alloy, ceramic, boride etc..

Sputtering Targets For Thin Film

Magnetron sputtering coating is a new type of physical vapor deposition method, in 2013 the evaporation coating method, its many advantages are quite obvious. As a mature technology, magnetron sputtering has been used in many fields.

 Sputtering Targets For Thin Film


Sputtering is one of the main technology of the thin film material preparation, it uses are generated in the ion source ion, in vacuum after accelerating aggregation, and the formation of high speed energy ion beam bombardment of solid surface, ion and a solid surface atoms undergoing kinetic exchange, make the solid surface atoms from solid and deposited on the surface of the substrate, bombarded solid is sputtering film deposition of the raw material, known as the sputtering target material. Various types of sputtered thin film materials have been widely used in semiconductor integrated circuit, recording medium, plane display and surface coating of workpiece.

Sputtering Targets For Thin Film


Sputtering target materials are mainly used in electronics and information industry, such as integrated circuit, information storage, liquid crystal display, laser memory, electronic controller parts; can also be used in the field of glass coating; can also used in wear-resistant materials, high temperature corrosion, high-grade decorative items such as industry.

According to the application areas are divided into microelectronics target, magnetic recording material and optical disc target, noble metal target material, thin film resistor target, conductive film target, surface modification of target and mask layer targets, decorative layer target material, electrode material, packaging material and other target


The principle of magnetron sputtering: the sputtering electrode (cathode) between the anode and the plus an orthogonal magnetic field and electric field, in a high vacuum chamber filled the inert gas (usually for Ar gas), permanent magnet on the surface of the target material formation 250 ~ 350 Gauss magnetic field. With the high voltage electric field group into orthogonal electric and magnetic fields. Under the action of electric field, Ar gas ionization in positive ions and electrons, the target with a negative high voltage, sent from the target pole electron ionization probability of the magnetic field and the working gas is increased, in the vicinity of the cathode form high density plasma, Ar ion in under the action of the Lorentz force accelerated toward the target surface, bombard the target surface with a high speed, the target is sputtered atoms obey the momentum conversion principle with high kinetic energy from the target surface toward the substrate deposition film. Magnetron sputtering is generally divided into two types: a tributary of the sputtering and RF sputtering, which is a tributary of the sputtering equipment is simple, in the sputtering of metal, the rate is also fast.

The radio frequency sputtering is more widely used, in addition to the conductive material, it can also be used as a non conducting material, and the material of oxide, nitride and carbide can be prepared by reactive sputtering. If the RF frequency is improved after microwave plasma sputtering, commonly used in the electron cyclotron resonance (ECR) type microwave plasma sputtering.
