Purity: 99.9%, Size: 3”, Thickness: 0.125”, Beige to White
Sputtering is a well-established technology capable of depositing thin films from a wide variety of materials onto substrates of diverse shapes and sizes.
The process using sputter targets is consistent and can be scaled from small research and development projects to larger production batches. The process with sputter targets can be adapted for medium to large substrate areas. The chemical reaction may occur on the target surface, in-flight, or on the substrate, depending on the process parameters. The numerous parameters make sputter deposition complex but offer experts substantial control over the growth and microstructure of the deposited film.
Applications of Sputtering Targets;
Sputtering targets are used for film deposition. Deposition using sputter targets is a method of applying thin films by sputtering, which 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 selected when a high degree of etching anisotropy is required and selectivity is not a concern.
Sputter targets are also utilized 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 using the sputtering target, the composition of the target material can be determined, and even extremely low concentrations of impurities can be detected.
Sputtering targets also have applications in space. Sputtering is one form of space weathering, a process that alters the physical and chemical properties of airless bodies, such as asteroids and the Moon.
