This tantalum wire evaporation material requires specific deposition source hardware and evaporation method compatibility for successful thin-film deposition. The material's high melting point and Z-ratio impose constraints on source selection and process control parameters.
- Evaporation Source Compatibility: The material must be used with a water-cooled e-beam hearth or a tungsten/tantalum support by RFQ to withstand the high melting point.
- Evaporation Method Limitation: E-beam evaporation is preferred; thermal evaporation is only acceptable for thin charges with a qualified setup due to material properties.
- Z-Ratio Process Control: The Z-ratio of 0.262 must be applied to deposition rate monitoring calculations for accurate film thickness control.
- Wire Geometry Compatibility: The wire diameter of 1.0 mm must be compatible with the source crucible or feed mechanism dimensions to ensure proper loading and evaporation.
Can Tantalum wire (99.99%, 1.0 mm dia.) be used for thermal evaporation, or is e-beam required?
E-beam evaporation is the preferred method for this Tantalum wire; thermal evaporation is only acceptable for thin charges in a qualified setup. The product specification explicitly states 'E-beam evaporation preferred; thermal only for thin charge/qualified setup' and recommends a water-cooled e-beam hearth or W/Ta support by RFQ.
What evaporation source configurations are compatible with Tantalum wire (1.0 mm diameter) for thin-film deposition?
The Tantalum wire is compatible with a water-cooled e-beam hearth or a W/Ta support by RFQ. The product description lists these as the supported evaporation source configurations, and buyers must confirm deposition-source geometry before ordering.
What is the significance of the Z-ratio (0.262) for Tantalum wire during e-beam evaporation?
The Z-ratio of 0.262 is a tooling factor used in quartz crystal microbalance (QCM) monitoring to calibrate film thickness during e-beam evaporation. This value is specific to Tantalum and is provided in the technical specifications to enable accurate deposition rate control.
Tantalum (Ta) evaporation wire (99.99%, 1.0 mm diameter) offers high-purity feedstock for vacuum thin-film deposition, with a melting point of 2,996°C and density of 16.6 g/cm³, making it suitable for e-beam evaporation but requiring careful source matching and infrastructure for thermal evaporation.
Positive
- High-purity 99.99% tantalum: The 99.99% purity specification supports demanding thin-film applications requiring low contamination and consistent film properties.
- Consistent wire geometry: The 1.0 mm diameter wire form enables reproducible source loading and uniform evaporation behavior in e-beam or qualified thermal setups.
Trade-offs
- E-beam evaporation preferred: Thermal evaporation is only recommended for thin charges in qualified setups; e-beam evaporation is required for standard use, limiting deposition hardware compatibility.
- High melting point and density: With a melting point of 2,996°C and density of 16.6 g/cm³, the material demands water-cooled e-beam hearths or specialized support (W/Ta by RFQ) and may not be suitable for all thermal evaporation systems.
