Products Description
Hafnium is a high melting point, corrosion-resistant transition metal with important applications in semiconductors, nuclear industry, and high-temperature coatings.
Hafnium sputtering target has the same performance as metal hafnium (Hf). Hafnium with melting point of 2233°C, boiling point of 4603°C, and density of 13.31g/cm3. It is a shiny silver-gray transition metal. Metal hafnium has moderate strength, good corrosion resistance, and high neutron absorption capacity. It is widely used in the atomic energy industry. Hafnium can form a variety of alloys and can also be used as a surface coating for base metals. We can provide imported high-purity hafnium with low-zirconium, which can be processed into targets and particles.
Application of hafnium sputtering target
(1) Semiconductor industry
High-k gate material: HfO₂ thin film is used to replace SiO₂ (process below 45nm).
Barrier layer: HfN or HfC prevents copper interconnect diffusion.
(2) Nuclear industry
Neutron absorption layer: Hf's high neutron capture cross section (105 barns) is used for nuclear reactor control rod coating.
(3) High temperature protection
Aerospace engine coating: Hf-Ta or Hf-Si alloy target material is used to prepare ultra-high temperature resistant (>1500°C) thin film.
(4) Optical coating
Extreme ultraviolet (EUV) optical elements: Hf/Si multilayer film reflector (13.5nm wavelength).
