Understanding the physical vapor deposition (PVD) process of metallic coatings on an inorganic substrate is essential for the packaging and semiconductor industry. Mo thin films were sputtering deposited on glass substrates. [5] This bonding procedure is most commonly used for Si or glass wafers that are coated with an Au/Al film and partly with adhesive layer. 999%) is available in various forms, purities, sizes, and prices, for use in semiconductor, film coating, physical vapor deposition (PVD) display and optical applications. Available in purities from 99. Materials and Methods Thin films of germanium–gold alloy were fabricated by magnetron sputtering from. Chemical Formula: Pt Catalog Number: ST0035 CAS Number: 7440-6-4 Purity: 99. Since its discovery during ancient times, it has been utilized as jewelry, coins, and tools. It is a very efficient procedure to deposit multilayered films for mirrors or magnetic films for spintronic devices.
