Tantalum Evaporation Data

Tantalum is a refractory metal with a very high melting point and relatively low vapor pressure. These characteristics are important when selecting an appropriate evaporation method.

Because of the high temperatures required to achieve useful vapor pressure, electron-beam evaporation is generally a suitable method for tantalum deposition.

Heeger Materials' Thin Film Evaporation Guide lists e-beam evaporation as an excellent method for Ta and notes that high vacuum is important for mitigating oxygen incorporation in deposited films.

Tantalum for E-Beam Evaporation

Tantalum's high melting point makes e-beam evaporation particularly useful because the electron beam can deliver concentrated energy directly to the evaporation material.

For tantalum deposition, process considerations may include:

• Evaporation-source geometry
• Material purity
• Vacuum level
• E-beam power
• Deposition rate
• Substrate temperature
• Oxygen control
• Crucible or hearth configuration
• Desired film thickness and properties

Actual deposition conditions should be optimized for the specific evaporation system and desired thin-film characteristics.

Why Purity Matters

Purity is an important consideration for evaporation materials because impurities in the source material can affect deposited-film composition and performance.

Higher-purity tantalum may be appropriate for demanding semiconductor, electronic, optical, and research applications where contamination control is critical.

When requesting material, specify both the required nominal purity and any critical individual impurity limits.

For high-purity requirements, request a lot-specific Certificate of Analysis (COA).

Tantalum Evaporation Material Applications

Semiconductor & Electronic Thin Films

High-purity tantalum evaporation materials can be used in research and manufacturing involving tantalum thin films for semiconductor and electronic applications.

Optical Coatings

Tantalum can be deposited in thin-film systems for selected optical and functional coating applications.

PVD Thin-Film Deposition

Tantalum pellets, pieces, and slugs can be used as source materials in vacuum PVD systems where high-purity tantalum films are required.

Electron-Beam Evaporation

Due to tantalum's high melting point, e-beam evaporation is an important deposition route for tantalum source materials.

Research & Development

Small quantities and custom tantalum evaporation forms are suitable for universities, laboratories, coating development, prototype deposition, and materials research.
