Characteristics of Molybdenum sputtering target

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 of Molybdenum sputtering target

Electronic Industry: Molybdenum sputtering targets are used to deposit films in integrated circuits, such as barrier and metallization layers, and in flat-panel displays for TFT and back electrodes, improving device performance and reliability.

Optical Field: Used to deposit optical films like mirrors and filters, molybdenum targets provide high reflectivity, low absorption, and excellent infrared optical performance.

Decorative Industry: Through sputtering, molybdenum targets produce metallic, wear-resistant coatings for jewelry, watches, and automotive interiors, enhancing aesthetics and durability.

Energy Field: In solar cells and thin-film batteries, molybdenum targets are used to deposit back electrodes or thin-film electrodes, improving conductivity, efficiency, and charge-discharge performance.

Packaging and Storage

Molybdenum sputtering targets are usually packed in protective, anti-moisture and anti-oxidation materials, often with foam or padding to prevent scratches and damage during transport.

They should be stored in a clean, dry, and ventilated environment, away from humidity, corrosive chemicals, and high temperatures, to maintain surface quality and performance.
