Common uses for refractory metal sputter targets include:
- Diffusion barriers: Tantalum, molybdenum, and tungsten thin film layers can prevent inter diffusion between two materials in electronic devices.
- Electrodes: Molybdenum and tungsten thin films are deposited for their resistivity and good ohmic contact properties.
- Optical coatings: Reactively sputtered tantalum and niobium films have a desirably high refractive index and low absorption.
Key markets for sputtering include many electronic sectors such as semiconductor, flat panel display, touch screens, photovoltaics and electo-chromic glass. Many of these applications require extreme purity (> 99.95 %) with chemical and metallurgical uniformity. H.C. Starck Solutions consistently provides such materials to give the best performance for physical vapor deposition.
Materials & Specifications
H.C. Starck Solutions tantalum products, like all of our products, are characterized by their fine, uniform, high density microstructure and controlled texture, which promotes uniform sputtering rates and generally superior sputtering behavior. We offer different grades of tantalum sputter target plates, ranging from 99.95% purity to 99.995%, to meet the specific application requirements of our customers.
We supply pure tungsten sputter target plates at purity levels of up to 99.95% at full density with fine uniform grain size through the thickness. Our pure molybdenum sputter targets are offered in both planar and tubular configurations with purity levels of up to 99.95%. Other materials are also available including MoW, MoNb and our exclusive DynaMoTM alloy for touch screen applications.
