Molybdenum metal

Molybdenum metal sputtering target is a key material with high purity, high density, good electrical and thermal conductivity, excellent corrosion resistance, prepared by powder metallurgy method or melting method, and widely used in sputtering coating in the fields of electronics, optics, decorative and energy.

Characteristics

Chemical formula: Mo

Atomic weight: 95.94

Density: about 10.28 g/cm³

Melting point: 2623°C

High density: Its high density characteristics help to better control the emission and deposition of sputtered particles during the sputtering process, resulting in a better thickness uniformity of the film and a denser structure, thus improving the performance of the film.

Good electrical and thermal conductivity: Molybdenum metal has good electrical and thermal conductivity, which can effectively transfer the current and heat during the sputtering process to ensure the stability of the sputtering process, and at the same time help to improve the growth quality of the film and the bonding force with the substrate.

Excellent corrosion resistance: it has good corrosion resistance to most chemicals, and can remain stable in different working environments, not easy to be corroded or oxidized, which prolongs the service life of the sputtering target, and also ensures the chemical stability of the prepared film.

Applications

Electronic industry: in the integrated circuit manufacturing, for the preparation of metallization layer, barrier layer and other films, such as in the chip interconnection structure, molybdenum metal film can be used as a tungsten plug blocking layer to prevent the diffusion of tungsten and silicon, to improve the performance and reliability of the chip; in the flat-panel display manufacturing, it can be used to prepare thin-film transistor (TFT) electrodes, back electrodes and so on, to improve the display’s electrical performance and display effect.

Optical field: It can be used for the preparation of optical films, such as mirrors and filters. Molybdenum metal film has good reflectivity and low absorption rate, and has excellent optical performance in the infrared band, which can be used to manufacture infrared mirrors, laser mirrors and other optical components to improve the performance of optical systems.

Decorative industry: through sputtering coating technology, a layer of molybdenum metal film is plated on the surface of various materials, which can obtain a decorative effect with metallic luster and good abrasion resistance, and is widely used in the fields of jewelry, watches, automobile interiors, etc., to improve the aesthetics and added value of products.

Energy field: in the manufacture of solar cells, molybdenum metal film can be used as the back electrode material, with good conductivity and adhesion to the silicon substrate, can effectively collect and transmit the current, improve the photoelectric conversion efficiency of solar cells; in the manufacture of lithium-ion batteries, it can be used for the preparation of thin film battery electrode materials, improve the performance of electrodes and battery charging and discharging performance.
