| Process Overview | 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. 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 allow experts a large 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. By 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. |
| Material Description | Aluminum is lightweight yet strong. Aluminum is commonly alloyed with elements such as copper and silicon to enhance structural and performance properties. Aluminum Silicon Copper (AlSiCu) alloys are known for very high strength compared to Aluminum Silicon alloys, making them ideal for aerospace and transportation applications. |
| Performance Features | Aluminum Silicon Copper sputtering targets have excellent casting and machining characteristics. They offer good corrosion resistance and weldability, making them suitable for engine parts, gas and oil pans, and general commercial applications. High-purity AlSiCu targets can also be used for semiconductor applications, forming a uniform thin film. |
