Maintenance And Handling Of Metal Sputtering Targets
Storage: Store metal sputtering targets in a dry, low humidity,and temperature-controlled environment, preferably inside avacuum-sealed package, to prevent oxidation and other forms ofcontamination.
Cleaning: Before and after use, clean the surface of the targetswith ethanol to remove debris, oil, or other non-target materialsto improve target cleanliness.
Handling: Handle metal sputtering targets with clean and drygloves or tools to avoid damage and prevent contamination arisingfrom handling.
Mounting: Mount the targets using clean target holders to ensurethat the target is entirely in contact with the holder's surface,avoid damage, and improve the consistency of the deposition.
Regular Inspection: Regularly inspect the metal sputteringtargets for any damage or deteriorations such as cracks, pitting,or corrosion that may affect the target's performance and ifnecessary, replace them.
Cleaning Frequency: Cleaning frequency should be determineddepending on the frequency of use, the type of material, and theproduction application.
Protect from Bumps and Scratches: Handle the targets with care.Avoid placing them in a position that can lead to bumps, chips,or scratches, which can damage the targets' surface and affectthe quality of the thin films deposited.
Manufacturing Process Of Metal Sputtering Targets
Material selection: The first step is selecting the righthigh-purity metal for the sputtering target. The metal istypically chosen based on the target application, such aselectronics, optics, or semiconductor applications.
Melting: The metal is melted in a high-temperature furnace,typically using a process known as vacuum arc melting orinduction melting. This process can remove impurities from themetal and ensure high purity.
Casting: Once the metal is melted, it is cast into the desiredtarget shape using casting molds. Depending on the shape requiredfor the sputtering process, the casting mold may be a flat plateor a cylindrical tube.
Machining: After casting, the metal sputtering target is machinedinto its final shape, typically using CNC machining or wire EDMcutting. This process ensures precise dimensions and smoothsurface finish.
Finishing: Finally, the sputtering target is polished to ensure ahigh-quality surface finish and to remove any burrs or roughedges. This step is critical to ensure the uniformity andconsistency of the sputtering process.
