Sputtering Targerts

Targeting leading quality 

Our product portfolio of PVD materials includes sources for metal and metal-oxide films for semiconductor, display, LED and photovoltaic devices. At Praxair, we have earned our reputation as a leading supplier through extensive research and development, and dedication to produce the highest quality sputtering targets. Explore our sputtering target product portfolio below.


AdvanTage™ Tantalum Targets

These targets provide consistent, reproducible process performance with high thickness uniformity and repeatable target-to-target sputtering deposition. The elimination of texture banding during fabrication produces a uniform microstructure, which delivers improved early-life stability and consistent-through-life sputter performance.

Fine-Grain Copper (Cu) and Copper Alloy Targets

With uniform microstructure and controlled texture, our fine grain 6N copper and copper alloy targets offer consistent performance and reliability, with increased target life. The well-controlled fine-grain microstructure enables innovative designs and higher yield strength allows for monobloc target structures, which exhibit minimal deflection and increased target life of up to 50%.

Ultrafine-Grain Aluminum (Al) Alloy Targets

Using advanced metallurgical fabrication techniques, our aluminum and aluminum-copper (Al-0.5Cu) targets exhibit enhanced yield strengths, with a nominal grain size of 0.5 µm, compared to 40-50µm obtained through conventional processing. The improved yield strength permits single-piece designs, which extend the life of our targets.

Long-Life Aluminum (Al) Targets (RE-Al â PLUS) 

Designed to improve the cost of ownership for aluminum deposition on 200mm wafers, the RE-Al â PLUS target demonstrates excellent performance throughout its rated lifetime of 1600 kWh (equivalent to 9,500 1-µm films).

When used with electrostatic chuck shield kits, the RE-Al â PLUS target can significantly increase the interval between kit and target replacements, allowing for increased tool utilization. In addition to the RE-Al â PLUS target, the RE-Al Supreme target is available with the same benefits for 150mm wafer processing.

Tungsten W Targets (high-purity, high-density)

In order to achieve optimal film properties and minimize particle generation, it is essential to control tungsten target purity, density, grain size and orientation. Through a tightly controlled manufacturing process, Praxair can deliver 5Ns (99.999%) pure W targets with a density greater than 99.7%. High-purity Ti-W, and W-Si targets are also available for semiconductor, solar and other thin film processes.
