Purity: 99.999%, Size: 1”, Thickness: 0.125”
Sputtering is a proven technology capable of depositing thin films from a wide variety of materials onto diverse substrate shapes and sizes.
The process with sputter targets is repeatable and can be scaled up from small research and development projects. The process with sputter targets can be adapted to production batches involving medium to large substrate areas. The chemical reaction can occur on the target surface, in-flight, or on the substrate depending on the process parameters. The many parameters make sputter deposition a complex process but provide experts with a high degree of control over the growth and microstructure of the area.
Applications of Sputtering Targets
Sputtering targets are used for film deposition. The deposition made by sputter targets is a method of depositing thin films by sputtering that involves eroding material from a “target” source onto a “substrate” such as a silicon wafer.
Semiconductor sputtering targets are used to etch the target. Sputter etching is chosen in cases where a high degree of etching anisotropy is needed and selectivity is not a concern.
Sputter targets are also used for analysis by etching away the target material.
One example occurs in secondary ion spectroscopy (SIMS), where the target sample is sputtered at a constant rate. As the target is sputtered, the concentration and identity of sputtered atoms are measured using mass spectrometry. With the help of the sputtering target, the composition of the target material can be determined, and even extremely low concentrations of impurities are detected.
Sputtering targets also have applications in space. Sputtering is one of the forms of space weathering, a process that changes the physical and chemical properties of airless bodies, such as asteroids and the Moon.
Aluminum is both lightweight and high-strength. Aluminum plating is ideal for use on motorcycles, automobiles, and aircraft. Aluminum is usually alloyed with a range of elements to enhance performance and structural properties, including copper and silicon.
Aluminum silicon copper alloys are well-known for very high strength compared with aluminum silicon alloys. Due to their high strength, aluminum silicon copper sputtering targets are suitable for use in the aerospace and transportation sectors.
Aluminum silicon copper sputtering targets have excellent casting and machining characteristics. Corrosion resistance and weldability of this alloy are very good, making it suitable for use in engine parts, gas and oil pans, and general commercial applications.
Aluminum silicon copper sputtering targets can also be used for semiconductor applications. Since this alloy is of high purity, it forms a uniform film.
