Potassium Niobate Sputtering Target Features

Potassium Niobate (KNbO₃) Sputtering Target is a ferroelectric and piezoelectric material commonly used in optical, electro-optic, and nonlinear applications. In addition to its sensitivity to moisture, it offers several key features:

  • High Nonlinear Optical Coefficient: KNbO₃ is widely used in second harmonic generation (SHG) and frequency doubling of lasers.

  • Strong Ferroelectric and Piezoelectric Properties: Ideal for thin-film applications in sensors, actuators, and electro-optic modulators.

  • Perovskite Crystal Structure: Ensures good lattice matching with oxide substrates, making it suitable for epitaxial growth in thin film research.

  • Moderate Sputtering Rate: Allows for controlled deposition, though proper process parameters and substrate heating are important.

  • Moisture Sensitivity: Requires dry handling and storage, as exposure to humidity can cause surface hydrolysis and reduce target life.

Overall, KNbO₃ targets are best used in vacuum deposition environments with strict moisture control to preserve their functional properties.

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).
