Aluminium Scandium Germanium Tantalum Alloy Target

Specifications

Product Features

Prepared from high-purity feedstock under controlled processing for stable and uniform thin-film deposition.

Applications

Aluminum-scandium-germanium-tantalum quaternary alloy targets are used for one-step sputtering of 5G millimeter-wave AlScGeN piezoelectric films, while tantalum contributes natural diffusion-barrier properties. They are also used for IGZO high-end display backplane doping and FeRAM ferroelectric memory composite films, simplifying device film-stack processes. Additional applications include buffer layers for third-generation semiconductor power devices, passivated electrodes for perovskite photovoltaics, and high-temperature aerospace protective coatings. In displays, they can replace aluminum and aluminum-neodymium targets to reduce hillock issues during coating and help panels withstand higher operating-temperature conditions.
