Cobalt Oxide Sputtering Target Description

The Cobalt Oxide Sputtering Target from TFM is an oxide sputtering material with the chemical formula CoO.

Cobalt

Cobalt is a chemical element whose name originates from the German word ‘kobald,’ meaning goblin. It was first mentioned in 1732 and observed by G. Brandt. The chemical symbol for cobalt is “Co,” and its atomic number is 27. Cobalt is located in Period 4, Group 9 of the periodic table, within the d-block. Its relative atomic mass is 58.933195(5) Dalton, with the number in brackets indicating the measurement uncertainty. Cobalt is essential in the production of high-strength alloys and is widely used in batteries, magnets, and catalysts.

OxygenOxygen is a chemical element that originated from the Greek ‘oxy’ and ‘genes’ meaning acid-forming. It was first mentioned in 1771 and observed by W. Scheele. The isolation was later accomplished and announced by W. Scheele. “O” is the canonical chemical symbol of oxygen. Its atomic number in the periodic table of elements is 8 with a location at Period 2 and Group 16, belonging to the p-block. The relative atomic mass of oxygen is 15.9994(3) Dalton, the number in the brackets indicating the uncertainty.

Cobalt Oxide Sputtering Targe Handling Notes

  • Indium Bonding: Indium bonding is recommended for the CoO sputtering target due to its brittleness and low thermal conductivity, which make it less suitable for traditional sputtering methods.
  • Thermal Conductivity: This material has low thermal conductivity and is susceptible to thermal shock. Proper handling and bonding are essential to avoid damage during the sputtering process.

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).
