Preparation of CIGS absorber layer

1. Preparation of Cu/In film by magnetron sputtering In order to accurately control the element ratio of Cu/In, CuIn film is prepared by co-sputtering method. That is, the Cu/In alloy target and the In elemental target are simultaneously sputtered in the same sputtering chamber. The distribution of Cu/In content has a great influence on the...

Advantages and disadvantages of ion beam sputtering

Ion beam sputtering is a thin film process technology that uses an ion source to sputter a target onto a substrate. Compared to other PVD technologies, ion beam sputtering is more accurate and can accurately control the thickness of the substrate. Its main advantages and disadvantages are as follows: Advantages Sputter coating utilizes momentum exchange...

Five sputter coating technologies

Unbalanced magnetron sputtering If the magnetic fluxes of the inner and outer magnetic pole sections of the cathode by magnetron sputtering are not equal, it is called an unbalanced magnetron sputtering cathode. The magnetic field of the common magnetron sputtering cathode is concentrated near the target surface; the magnetic field of the unbalanced magnetron sputtering...

Four main molding methods for ITO (Indium Tin Oxide) targets

As is known, the ITO sputtering target is a black-gray ceramic semiconductor formed by a series of production processes after indium oxide and tin oxide powder are mixed in a certain proportion, and then sintered in a high temperature atmosphere (1600 degrees, oxygen sintering). The ITO film was subjected to magnetron sputtering to oxidize the ITO...

Influencing Factors of the Sputtering Deposition Rate of Magnetron Targets

Sputter deposition rate is a parameter that characterizes the film formation rate. In addition to the influencing factors such as the type and pressure of the working gas, target type and area size of the “sputter etched area”, and target surface temperature and target surface magnetic field strength, the deposition rate is also directly affected...

What are the uses of PVD (Physical Vapor Deposition) coating?

PVD(Physical Vapor Deposition) coating, a physical terminology which is seemingly difficult to understand, actually is connected closely to our daily lives. Your beautiful jewelry, expensive camera and sharp knives may all use PVD coating. If you want to know more about PVD coating, just continue to read.   What is PVD coating? PVD Coating, or...
