Hafnium evaporation material requires deposition in a compatible e-beam source with a water-cooled copper hearth and appropriate liner such as graphite, Al2O3, BN, or Ta. Handling must avoid contamination to maintain 99.99% purity for consistent thin-film deposition.
- Evaporation Source Compatibility: Use only in a compatible e-beam evaporation source with a water-cooled copper hearth and a graphite, Al2O3, BN, or Ta liner.
- Purity Maintenance: Maintain 99.99% purity by handling with clean tools and storing in a clean, dry environment to prevent contamination.
- Melting Point Consideration: The material's melting point of 2,227°C determines the required evaporation power and source temperature.
- Z-Ratio Impact: The Z-ratio of 0.36 affects film thickness monitoring and must be accounted for in process control.
How does the Z-ratio of 0.36 for hafnium evaporation material affect quartz crystal microbalance (QCM) thickness monitoring during e-beam deposition?
The Z-ratio of 0.36 is used to correct the acoustic impedance mismatch between the quartz crystal and the deposited hafnium film, ensuring accurate thickness monitoring via QCM. This value is specific to hafnium (Hf) and must be entered into the deposition controller; an incorrect Z-ratio leads to systematic film thickness errors. The product specification lists density as 13.31 g/cm³ and melting point as 2,227°C, which together with the Z-ratio define the tooling factor for e-beam evaporation processes.
What liner materials are compatible with hafnium evaporation in a water-cooled copper e-beam hearth?
The product description explicitly states that graphite, Al₂O₃, BN, and Ta liners are compatible with the water-cooled copper e-beam hearth for hafnium evaporation. These liner materials withstand the high melting point of hafnium (2,227°C) and prevent contamination of the deposited film. Buyers should confirm that their deposition source geometry matches the chosen liner type before ordering.
Why is e-beam evaporation the preferred method for hafnium (Hf) evaporation material, and what infrastructure is required?
E-beam evaporation is preferred for hafnium due to its high melting point of 2,227°C, which exceeds the capability of thermal evaporation sources. The required infrastructure includes a water-cooled copper e-beam hearth and a compatible liner (graphite, Al₂O₃, BN, or Ta) to contain the molten material. The product is supplied as 1–3 mm pieces, which are suitable for loading into e-beam crucibles, and the Z-ratio of 0.36 must be used for accurate QCM thickness monitoring during deposition.
Hafnium (Hf) evaporation material in pieces (1-3 mm, 99.99% purity) is suitable for e-beam deposition requiring high-purity metallic films. The specified particle size and high melting point (2,227°C) support controlled evaporation in compatible water-cooled copper hearths with appropriate liners.
Positive
- High purity 99.99%: The 99.99% purity specification enables consistent thin-film stoichiometry and reduces contamination risk in vacuum deposition processes.
- Defined particle size 1-3 mm: The 1-3 mm piece size facilitates controlled loading into e-beam evaporation sources and supports uniform evaporation rates.
Trade-offs
- Specific hardware compatibility required: Optimal use requires a water-cooled copper e-beam hearth with graphite, Al2O3, BN, or Ta liner; alternative source configurations may not achieve stable evaporation.
- High melting point and process sensitivity: With a melting point of 2,227°C, density of 13.31 g/cm³, and Z-ratio of 0.36, deposition parameters must be carefully calibrated to avoid source damage or film non-uniformity.
