What are the Uses of Metal Sputtering Targets?

What is the “target”?

The target refers to the target material. They can be used in high-energy laser weapons; different power densities, different output waveforms, and different wavelengths of lasers can have different killing effects when interacting with different targets. Another major use for them is for sputtering in physical film coating.

What is the “sputtering target”?

Magnetron sputtering coating is a new type of physical vapor deposition method, and its advantages in many aspects are quite obvious compared with the earlier evaporation coating method. As a relatively mature technology that has been developed, magnetron sputtering has been applied in many fields. Sputtering targets serve as source materials in magnetron sputtering coatings.

What are the application areas?

1: Microelectronics field

2: Target for flat panel display

3: Targets for storage technology

Sputtering materials are mainly used in electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memories, electronic control devices, etc.; they can also be used in the field of glass coating; they can also be applied to wear-resistant materials, high temperature corrosion resistance, high-grade decorative products and other industries.

The technological development trend of target materials is closely related to the development trend of thin-film technology in the downstream application industry. As technology in the application industry improves on film products or components, target technology should also change. In recent years, flat panel displays (FPDs) have largely replaced the market for computer monitors and televisions, which are mainly cathode ray tubes (CRTs), and will greatly increase the technical and market demand for ITO targets.

Stanford Advanced Materials (SAM) Corporation is a global supplier of various sputtering targets such as metals, alloys, oxides, ceramic materials. For more information, please visit https://www.sputtertargets.net/.

Applications of High Purity Copper Sputtering Target

The copper sputtering target is a coating material made of metallic copper, which is suitable for DC bipolar sputtering, three-pole sputtering, four-stage sputtering, radio frequency sputtering, counter target sputtering, ion beam sputtering, and magnetron sputtering, etc. It can be applied to manufacture reflective films, conductive films, semiconductor films, capacitor films, decorative films, protective films, integrated circuits, displays, and etc. Compared with other precious metal sputtering targets, the price of copper targets is lower, so the copper target is the preferred target material under the premise of satisfying the function of the film layer.

Copper sputter targets are divided into the planar copper target and rotary copper target. The former is sheet-shaped, with round, square, and the like; the latter is tubular, and the utilization efficiency is high.

High-purity copper sputter targets are mainly used in electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memories, electronic control devices, etc.; they can be applied to the field of glass coating; they can also be applied to wear-resistant materials, high-temperature corrosion resistance, high-end decorative supplies and other industries.

Information storage industry: With the continuous development of information and computer technology, the demand for recording media in the world market is increasing, and the corresponding target media for recording media is also expanding. Related products include hard disks, magnetic heads, and optical disks. (CD-ROM, CD-R, DVD-R, etc.), a magneto-optical phase-change optical disc (MO, CD-RW, DVD-RAM).

Integrated circuit industry: In the field of semiconductor applications, sputtering targets are one of the main components of the world target market. They are mainly used for electrode interconnect film, barrier film, contact film, optical disk mask, capacitor electrode film, and resistive film, etc.

Flat-panel display industry: Flat panel displays include liquid crystal displays (LCDs), plasma displays (PDPs), and the like. At present, LCD is the main market in the flat panel display market, and its market share exceeds 85%. LCD is considered to be the most promising flat display device and is widely used in notebook monitors, desktop monitors and high definition televisions. The manufacturing process of the LCD is complicated, in which the reflective layer, the transparent electrode, the emitter and the cathode are all formed by a sputtering method, and therefore, the sputtering target plays an important role in the manufacture of LCD.

Introduction to Aluminum, Aluminum Alloy and Aluminum Sputtering Target

Aluminum is a light metal with low density (2.79/cm3), good strength and excellent plasticity. As for aluminum alloy, the strength of super-hard aluminum alloy can reach 600Mpa, and the tensile strength of ordinary hard aluminum alloy can reach 200-450Mpa, which is much higher than steel in steel. Therefore, aluminum and aluminum alloy are widely used in machinery manufacturing.

The conductivity of aluminum is second only to silver and copper, so aluminum is used in the manufacture of various conductors. Aluminum also has a good thermal conductivity that can be used as a variety of heat dissipating materials. Besides, aluminum has good corrosion resistance and excellent plasticity, and is suitable for various pressure processing.

Aluminum alloy

Aluminum alloy can be divided into the deformed aluminum alloy and the cast aluminum alloy according to the processing method.

The deformed aluminum alloy can be further divided into a non-heat treatable reinforced aluminum alloy and a heat treatable reinforced aluminum alloy. Non-heat-treated reinforced aluminum alloy cannot improve the mechanical properties by heat treatment, and can only be strengthened by cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and rust-proof aluminum. The heat-treatable reinforced aluminum alloy can be improved in mechanical properties by heat treatment such as quenching and aging, and can be classified into hard aluminum, wrought aluminum, super-hard aluminum, and special aluminum alloy. The aluminum alloy can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.

Cast aluminum alloy can be divided into aluminum silicon alloy , aluminum-copper alloy, aluminum-magnesium alloy and aluminum-zinc alloy according to chemical composition. Cast aluminum alloy is classified into four types according to the main elements other than aluminum in the composition: silicon, copper, magnesium and zinc.

Pure aluminum products

Pure aluminum products are divided into two categories: smelting and pressure processing. The former is represented by chemical composition Al, and the latter is represented by LG (aluminum, industrial). The aluminum sputtering target is a kind of pure aluminum product.

Pressure processing aluminum alloy

Aluminum alloy pressure processing products are divided into seven categories: rustproof (LF), hard (LY), forged (LD), superhard (LC), coated (LB), special (LT) and brazed (LQ). The state of the commonly used aluminum alloy material is three types of annealing (M igniter), hardening (Y), and hot rolling (R).

Aluminum sputtering target

The aluminum sputtering target is one of the sputtering targets used in the vacuum coating industry, and is therefore called aluminum sputtering target. The aluminum target is obtained after a series of processing of high-purity aluminum. It is available in a specific size and shape, which is mounted on a vacuum coater to form a film on the surface of the substrate by sputtering.
