ISO Molds for Target

The target material is one of the main materials for preparing thin films. It is mainly used in integrated circuits, flat panel displays, solar cells, recording media, smart glass, etc., and has high requirements for material purity and stability. The working principle of sputtering target: Sputtering is one of the main technologies for preparing thin film materials. It uses the ions generated by the ion source to accelerate and gather in a vacuum to form a high-speed energy ion beam, which bombards the solid surface. Kinetic energy exchange occurs with the atoms on the solid surface, so that the atoms on the solid surface leave the solid and deposit on the surface of the substrate. The bombarded solid is the sputtering target. The development trend of the target is: high sputtering rate, grain orientation control, large size, high-purity metal.

The hot isostatic pressing method is to put the powder or the pre-pressed blank into the package, then vacuumize the inside of the package, weld and seal it, put it in a high-pressure container, and make the powder sinter under high temperature and equal pressure, forming and sintering simultaneously. In the development of ITO targets, it is difficult to obtain high-density and large-size materials by the hot isostatic pressing technology adopted in the early stage. With the emergence of the atmospheric pressure sintering method, the target material prepared by the hot isostatic pressing method is small in size, low in density, high in oxygen loss rate, expensive in equipment and high in cost, making hot isostatic pressing in The preparation of ITO ceramic targets no longer has a competitive advantage, and subsequent research and industrialization are gradually downplayed by the industry, but they are still more suitable for ceramic targets that require oxygen deficiency.

The cold isostatic pressing method is to put the pre-formed blank into the rubber sheath and immerse it in the high-pressure liquid to make it bear isotropic pressure, so as to realize the strengthening of the density of the green blank. Cold isostatic pressing is only to obtain the green body with the highest possible density, which makes the sintering and densification of the green body easier. Since cold isostatic pressing does not have the sintering ability of hot isostatic pressing, an independent sintering process is required to fire the green body. Cold isostatic pressing can press large-sized targets, and is currently the preferred molding method for most companies. Forming studies at home and abroad have shown that cold isostatic pressing can produce high-quality blanks that meet the requirements of ceramic targets. However, due to the limitation of the size of the chamber, the cold isostatic pressing will cause very expensive equipment investment, and there will be deformation problems when the green body is thinner and larger in size.
