Gadolinium Sputtering Target Description

Gadolinium

The gadolinium sputtering target is a silvery target made from high-purity gadolinium metal. Named after Johan Gadolin, a chemist, physicist, and mineralogist, gadolinium was first mentioned in 1880 by J. C. G. de Marignac, with isolation later achieved by F. L. de Boisbaudran. The chemical symbol for gadolinium is “Gd,” and it has an atomic number of 64, located in Period 6 and Group 3 of the periodic table, within the f-block. The relative atomic mass of gadolinium is 157.25(3) Dalton, with the number in brackets indicating uncertainty.

Gadolinium Sputtering Target Application

  • Gadolinium sputtering target is used for thin film deposition.
  • Gadolinium can be used for making gadolinium yttrium garnets in superconducting and microwave applications.
  • Gadolinium can also be used as a magnetic component for sensing both hot and cold variations.
  • Gadolinium compounds are used for producing phosphors for color TV tubes. It is used as an alloying element for better workability and improved resistance to high-temperature oxidation in chromium, iron, and their associated alloys.
  • Gadolinium ethyl sulfate has very low noise properties and can be used to mimic the performance of high-frequency amplifiers, like the maser.

Handling Notes

  • Bonding services for gadolinium sputtering targets are currently unavailable.
  • Due to its high chemical reactivity, gadolinium sputtering targets require oil packaging and thorough cleaning to prevent environmental reactions.

FAQ

It’s the source material (in solid form) used in sputter deposition to eject atoms or molecules that then form a thin film on a substrate.

Targets can be pure metals (e.g., gold, copper, aluminum), ceramics (e.g., Al₂O₃, SiO₂, TiO₂), alloys, or composites—chosen based on the film’s desired properties.

 

They are produced by processes such as melting/casting for metals or sintering (often with hot isostatic pressing) for ceramics and composite targets to ensure high density and purity.

 

In a vacuum chamber, a plasma (typically argon) bombards the target, ejecting atoms that travel and condense on a substrate, forming a thin film.

 

Key factors include the target’s purity, density, grain structure, and the sputtering yield (i.e. how many atoms are ejected per incident ion), as well as operating conditions like power density and gas pressure.

 

Operators monitor target erosion (often by measuring the depth of the eroded “race track”) or track total energy delivered (kilowatt-hours) until it reaches a threshold that can compromise film quality.

 

Fragile materials (such as many ceramics or certain oxides) and precious metals often require a backing plate to improve cooling, mechanical stability, and to allow thinner targets that reduce material costs.

 

DC sputtering is used for conductive targets, while RF sputtering is necessary for insulating targets (like many oxides) because it prevents charge buildup on the target’s surface.

 

In reactive sputtering, a reactive gas (e.g., oxygen or nitrogen) is introduced to form compound films on the substrate, but it may also “poison” the target surface if not carefully controlled.

 

Many manufacturers prefer to control raw material quality by sourcing their own powders; using external powders can risk impurities and inconsistent target properties.

 

Targets should be stored in clean, dry conditions (often in original packaging or re-wrapped in protective materials) and handled with gloves to avoid contamination, ensuring optimal performance during deposition.

Deposition rate depends on factors such as target material and composition, power density, working gas pressure, substrate distance, and the configuration of the sputtering system (e.g., magnetron design).
