Tantalum Oxide (Ta₂O₅) Sputtering Target

Tantalum Oxide (Ta₂O₅) Sputtering Target Description

Heeger Materials supplies high-purity Tantalum Oxide (Ta₂O₅) Sputtering Targets for optical coatings, semiconductor thin films, dielectric layers, electronic devices, display technologies, and research applications.

Ta₂O₅ is widely used as a thin-film material because of its high refractive index, excellent dielectric properties, chemical stability, and optical performance. These characteristics make tantalum oxide an important coating material for optical and electronic applications.

Our Ta₂O₅ sputtering targets are available in circular, rectangular, and custom geometries, with bonded and unbonded configurations available according to sputtering-system requirements.

Purity, target dimensions, density, surface condition, bonding method, and backing plate configuration can be customized according to customer specifications.

Tantalum Oxide Sputtering Target Specifications

Final specifications should be confirmed according to target size, density, bonding configuration, sputtering system, and application requirements.

Key Properties of Ta₂O₅

Tantalum pentoxide is an important functional oxide material for optical and electronic thin films.

Key characteristics include:

• High refractive index
• Excellent dielectric properties
• Good chemical stability
• Good thermal stability
• Low optical absorption in appropriate wavelength ranges
• Suitable for high-k dielectric applications
• Suitable for optical thin-film coatings
• High-purity target options
• Custom target dimensions
• Bonded target configurations

These properties make Ta₂O₅ particularly useful in advanced optical, semiconductor, and electronic coating systems.

Standard Target Dimensions

Circular Ta₂O₅ Targets

Standard circular target diameters include:

1" / 2" / 3" / 4" / 5" / 6"

Custom circular targets can be supplied in larger diameters according to manufacturing requirements, with the current product range listing sizes up to 21 inches.

Standard thicknesses include:

0.125" / 0.25"

Custom thicknesses are available upon request.

Rectangular Ta₂O₅ Targets

Standard rectangular target sizes include:

• 5" × 12"
• 5" × 15"
• 5" × 20"
• 5" × 22"
• 6" × 20"

Custom width, length, thickness, tolerance, and backing configurations can be reviewed according to your sputtering system.

Bonded Tantalum Oxide Sputtering Targets

Because tantalum oxide is a ceramic target material, appropriate target mounting, bonding, thermal management, and sputtering conditions are important.

Bonded Ta₂O₅ sputtering targets are available with backing plates according to customer requirements.

Bonding can help provide mechanical support and thermal transfer during sputtering, particularly for brittle ceramic target materials.

When requesting a bonded target, please provide:

• Target diameter or dimensions
• Target thickness
• Backing plate material
• Backing plate dimensions
• Bonding requirement
• Sputtering system
• Operating requirements, if applicable

Custom bonding configurations can be reviewed according to target geometry and equipment requirements.

Ta₂O₅ Sputtering Target Applications

Optical Coatings

Ta₂O₅ is widely used in optical thin-film systems because of its high refractive index and useful optical properties.

Applications include:

• Anti-reflective coatings
• Optical filters
• Multilayer optical coatings
• Laser optics
• Precision optical components

Semiconductor Thin Films

Tantalum oxide thin films are used in semiconductor and electronic applications where dielectric performance and material stability are required.

• High-k dielectric layers
• Insulating layers
• Thin-film capacitors
• Electronic thin films
• Semiconductor research

Display and Electronic Applications

Ta₂O₅ sputtering targets can be used in thin-film deposition for selected display, electronic, and functional coating applications.

Protective and Functional Coatings

Tantalum oxide thin films can also be investigated for applications requiring chemical stability, dielectric behavior, wear resistance, or other functional surface properties.

Research & Development

Standard and custom Ta₂O₅ targets are available for universities, laboratories, coating-development projects, prototype deposition, and materials research.

Why Target Density Matters

Density is an important specification for ceramic sputtering targets.

A dense and well-controlled target can support more consistent sputtering behavior and reduce problems associated with excessive porosity or structural defects.

For demanding applications, specify the required:

• Relative density
• Purity
• Target dimensions
• Surface condition
• Microstructure
• Bonding configuration

If your project has a minimum density requirement, include it with your inquiry rather than requesting only a generic “high-density” target.

Custom Ta₂O₅ Sputtering Targets

Heeger Materials can review custom tantalum oxide target requirements according to customer drawings and sputtering-system specifications.

Customization options include:

• Purity
• Circular diameter
• Rectangular dimensions
• Thickness
• Dimensional tolerances
• Target density
• Surface finish
• Flatness
• Custom geometry
• Bonding
• Backing plate material
• Backing plate dimensions
• Custom mounting features

For custom targets, attaching a technical drawing is recommended.

How to Specify a Ta₂O₅ Sputtering Target

For a faster and more accurate quotation, please provide:

Purity: Required Ta₂O₅ purity

Shape: Circular, rectangular, or custom

Dimensions: Diameter × thickness or width × length × thickness

Density: Minimum or target density, if specified

Surface Finish: If required

Bonding: Bonded or unbonded

Backing Plate: Material and dimensions

Sputtering System: Equipment/model if relevant

Quantity: Required number of targets

Drawing: Recommended for custom or bonded targets

Handling Considerations for Ta₂O₅ Targets

Tantalum oxide is a ceramic target material and should be handled carefully to reduce the risk of chipping, cracking, or mechanical damage.

Appropriate bonding and controlled sputtering procedures may be recommended depending on target dimensions, power conditions, backing configuration, and sputtering equipment.

For large or custom ceramic targets, please provide your operating and mounting requirements so the appropriate target configuration can be reviewed.

Delivery & Packaging

Typical lead time for tantalum oxide sputtering targets is 2–5 weeks, depending on target dimensions, purity, bonding requirements, and quantity.

Targets are carefully packaged to protect the target surface and reduce the risk of mechanical damage during transportation.

Technical documentation such as COA and SDS/MSDS can be supplied as applicable.
