This material is intended for use in vacuum thin-film deposition processes and requires careful matching of evaporation source hardware to material properties. Proper handling of the pellets, including confirmation of source geometry and process parameters, is essential to achieve consistent film quality and avoid equipment contamination.
- Evaporation Source Compatibility: Deposition must use a Ta/W boat, Ta liner, or water-cooled e-beam hearth with a liner to prevent material reaction with the source.
- Process Parameter Matching: The melting point of 1,529°C and Z-ratio of 0.74 must be considered when setting evaporation power and rate to achieve stable deposition.
- Pre-Installation Verification: Confirm the pellet size range of 1–10 mm is compatible with the source feeder or crucible geometry before loading.
- Documentation and Safety Review: Review the safety data sheet, certificate of analysis, and shipment conditions prior to handling to ensure laboratory compliance.
- Application Matching: Evaporation source hardware and process route should be matched to material behavior, melting point, and film requirements.
What is the significance of the Z-Ratio of 0.74 for erbium evaporation material in e-beam deposition?
The Z-Ratio of 0.74 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring during e-beam evaporation of erbium. It corrects for the acoustic impedance mismatch between the erbium film and the quartz crystal sensor, enabling accurate real-time film thickness control. This value must be programmed into the deposition controller to achieve correct thickness readings for this specific material.
Which evaporation source and liner materials are recommended for erbium (Er) pellet evaporation?
For erbium pellet evaporation, recommended source configurations include tantalum (Ta) or tungsten (W) boats, Ta liners, or a water-cooled e-beam hearth with liner. Both electron-beam and thermal/resistive evaporation methods are suitable, but the specific source hardware should be confirmed via RFQ based on the material's melting point of 1,529°C and deposition requirements.
How does the melting point of erbium (1,529°C) influence the evaporation method and source selection?
Erbium has a melting point of 1,529°C, which is relatively high for a pure metal evaporation material. This makes e-beam evaporation the preferred method to achieve sufficient vapor pressure without exceeding boat material limits. The product datasheet recommends using a water-cooled e-beam hearth with liner for this material, as well as Ta/W boats or Ta liners for thermal evaporation, to safely handle the high-temperature deposition process.
Erbium (Er) evaporation pellets at 99.9% purity and 1–10 mm size range are specified for e-beam or thermal evaporation, with defined density and Z-ratio enabling process matching. The product requires pre-order confirmation of deposition-source geometry and hardware compatibility, and the 1529°C melting point may necessitate water-cooled e-beam hearths or high-temperature liners.
Positive
- Defined purity and physical form: Supplied as 99.9% pure pellets in 1–10 mm size range, ensuring consistent material identity and loading geometry for vacuum thin-film deposition.
- Multi-source evaporation compatibility: Compatible with Ta/W boats, Ta liners, and water-cooled e-beam hearths with liners, supporting both thermal/resistive and e-beam evaporation workflows.
Trade-offs
- Pre-order compatibility verification required: Buyers must confirm deposition-source geometry, pack size, and certificate requirements before quotation to avoid mismatch with existing hardware.
- High melting point imposes process constraints: The 1529°C melting point necessitates water-cooled e-beam hearths or high-temperature liners, limiting compatibility with standard thermal evaporation boats.
