Yttrium metal

Yttrium metal sputtering target is a kind of silver gray metal target with high purity, high density, good electrical and thermal conductivity, widely used in the preparation of thin films in the fields of electronic devices, optical thin films, magnetic materials and so on.

Properties

Chemical formula: Y

CAS No.: 7440-65-5

Appearance: usually silver gray metallic luster

Good electrical and thermal conductivity: Yttrium metal itself has good electrical and thermal conductivity, in the sputtering process can quickly conduct current and heat, is conducive to the formation of a stable plasma, improve the sputtering rate, and to prevent the target material due to localized overheating and deformation or damage.

Applications

Electronic device manufacturing: In semiconductor integrated circuit manufacturing, it is used to deposit yttrium films as electrode materials, barrier layers or interconnect materials. Yttrium films have good electrical conductivity and chemical stability, which can improve the performance and reliability of electronic devices. In addition, in the manufacture of flat panel displays, such as liquid crystal displays (LCD) and organic light-emitting diode displays (OLED), it can be used to deposit transparent conductive films or functional films such as electron injection layers to improve the display effect and electrical properties of the display.

Optical film preparation: It can be used to prepare various optical films, such as high reflectivity films, anti-reflective films, optical filters and so on. Thin films formed by yttrium metal sputtering have specific optical constants and refractive indices, which can accurately control the propagation and reflection characteristics of light, and are widely used in the fields of optical instruments, laser equipment, optical communications, etc. to improve the performance and efficiency of optical systems.

Magnetic material preparation: it is the key material for the preparation of magnetic films such as yttrium iron garnet (YIG).YIG films have excellent magneto-optical and microwave properties, and have important applications in the fields of magneto-optical storage, microwave communications, and sensors. By sputtering Yttrium metal sputtering target, the composition, thickness and microstructure of YIG films can be precisely controlled, thus realizing the regulation of their magneto-optical and microwave properties.

Other fields: It can also be applied to the preparation of thin films in superconducting materials, catalysts, ceramic coatings and other fields. For example, in the preparation of superconducting films, yttrium, as one of the important constituent elements, can give superconducting materials special superconducting properties;

In the field of catalysts, yttrium films can be used as the carrier or active component of catalysts to improve the activity and selectivity of catalysts;

In the field of ceramic coatings, yttrium films can improve the surface properties of ceramic materials and enhance their hardness, wear resistance and corrosion resistance.
