Aluminum Chromium Sputtering Target Description

The aluminum chromium sputtering target from TFM is an alloy sputtering material containing aluminum (Al) and chromium (Cr). This combination allows the aluminum chromium sputtering target to benefit from the properties of both elements.

Aluminum

Aluminum:

  • Origin: Derived from the Latin name for alum, ‘alumen’ meaning bitter salt.
  • Discovery: First mentioned in 1825 by H.C. Ørsted, who also accomplished its isolation.
  • Symbol: Al
  • Atomic Number: 13
  • Position in Periodic Table: Period 3, Group 13, p-block
  • Relative Atomic Mass: 26.9815386(8) Dalton

Chromium

Chromium:

  • Origin: Derived from the Greek word ‘chroma’, meaning color.
  • History: Used as early as before 1 AD and discovered by the Terracotta Army.
  • Symbol: Cr
  • Atomic Number: 24
  • Position in Periodic Table: Period 4, Group 6, d-block
  • Relative Atomic Mass: 51.9961(6) Dalton

The aluminum chromium sputtering target harnesses the lightweight and corrosion-resistant properties of aluminum along with the hardness and high melting point of chromium. This makes it suitable for a wide range of high-performance applications in industries such as electronics, optics, and protective coatings.

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).
