Sputtering Target for Thin Film Deposition

Sputtering is a physical vapor deposition (PVD) process where atoms are ejected from the surface of a material when it is bombarded by high-energy particles. In sputtering deposition, a controlled gas, typically inert argon, is introduced into a vacuum chamber. A cathode is then electrically energized to create a self-sustaining plasma. The surface of the cathode that is exposed is known as the sputtering target.

Sputtering targets are usually solid pieces that come in various sizes and shapes. These targets can be made from pure metals, alloys, or compounds such as oxides or nitrides. The substrate, which is the object to be coated, can be a semiconductor wafer, a solar cell, an optical component, or many other types of materials. The thickness of the coatings typically ranges from angstroms to microns. The thin film can consist of a single material or multiple materials in a layered structure.

Applications of Sputtering Targets in Thin Film Deposition

Semiconductors

Semiconductor manufacturing relies heavily on thin-film deposition for creating essential components like transistors, diodes, and integrated circuits. Our sputtering targets are used to deposit thin, high-quality films of metals, oxides, nitrides, and other materials onto silicon wafers or gallium arsenide substrates to create microchips and semiconductor devices.

Optical Coatings

Optical coatings are applied to lenses, mirrors, displays, and other optical devices to control light reflection, transmission, and absorption. Our sputtering targets are used to deposit thin layers of materials like silicon dioxide (SiO2), titanium dioxide (TiO2), and magnesium fluoride (MgF2) to produce antireflection coatings, filters, and beamsplitters with high precision.

Solar Cells

Thin-film solar cells benefit from sputtering targets for the deposition of material layers such as cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and amorphous silicon. These materials are crucial for the absorption of sunlight and conversion of energy into electricity. Our sputtering targets ensure uniform deposition to maximize the efficiency of solar panel production.

Hard Coatings and Wear Protection

For industries requiring durable coatings with superior wear and corrosion resistance, such as automotive, aerospace, and tool manufacturing, our sputtering targets can be used to deposit hard coatings like titanium nitride (TiN), chromium carbide (CrC), and diamond-like carbon (DLC). These coatings improve the performance and lifespan of critical components by reducing friction and wear.

Glass and Display Manufacturing

In the flat-panel display and glass coating industries, thin-film deposition is essential for creating coatings that improve optical properties, such as reflective coatings for touch screens or transparent conductive films for LED displays. Our indium tin oxide (ITO) and zinc oxide (ZnO) sputtering targets are ideal for depositing these types of coatings.
