Tanaka begins shipments of SJeva, a high-quality Au deposition material
Tanaka Holdings Co. Ltd. announces the start of sample shipments of SJeva, a newly-developed, high-quality Au deposition material, by Tanaka Kikinzoku Kogyo. The new deposition material has higher purity than earlier products, making it possible to reduce the amount of precious metals used, increase productivity and cut costs by reducing processing, and raise recoverability and recyclability. By improving manufacturing methods, Tanaka Kikinzoku Kogyo successfully reduced the amount of non-metallic inclusions in the deposition material compared to conventional materials. Tanaka Kikinzoku Kogyo previously handled Au deposition materials with a purity of 4N (99.99% gold content) to 5N (99.999% gold content), and the new deposition material enhances the lineup of high-quality products. By using a deposition material with extremely low non-metallic inclusions, contaminants that collect on the surface during melting of the deposition material are reduced, eliminating the need for cleaning. The high-purity deposition material also makes it possible to shorten the preheating time before film formation, decreasing consumption of deposition material that does not contribute to film formation and reducing costs. In addition, the new deposition material contains low levels of gas, and as a result, a reduction in splash phenomenon from the deposition source during film formation can be expected, and it is possible to reduce the number of particles[4] that form on substrates, even during high-rate deposition. As a result of the above properties and benefits of the new deposition material, it is expected to contribute to higher end-user productivity and lower costs when manufacturing final products that use deposition materials such as micro-wiring and MEMS in the semiconductor fields as well as optical devices, LEDs, and medical equipment. Benefits of the New Deposition Material – Reduced number of cleaning processes Usually, various shapes of deposition materials including pellet, plate, ribbon, wire, and grain shapes are used depending on […]
