This evaporation material requires specific source hardware and process conditions for optimal deposition. The material's melting point, density, and Z-ratio must be matched to the evaporation method and source geometry.
- Evaporation Source Compatibility: Use only Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners for thermal or e-beam evaporation.
- Process Parameter Matching: Match the evaporation method (e-beam or thermal/resistive) to the material's melting point of 921°C and required film characteristics.
- Physical Form Handling: Ensure the pellet size range of 1-10 mm is compatible with the deposition source loading mechanism and feed rate.
What evaporation methods are compatible with Lanthanum pellets?
Lanthanum pellets support both e-beam and thermal/resistive evaporation methods by RFQ using Ta/W boat or Ta liner for thermal processes and water-cooled e-beam hearth with liner for e-beam deposition.
What boat or liner materials are recommended for evaporating Lanthanum?
Tantalum (Ta) or Tungsten (W) boats are recommended for thermal/resistive evaporation of Lanthanum pellets; a Ta liner is specified for use in water-cooled e-beam hearths to prevent contamination during deposition.
How does the Z-Ratio of Lanthanum affect deposition rate monitoring?
The Z-Ratio of 0.92 is used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness monitoring during Lanthanum evaporation; this value accounts for acoustic impedance mismatch between the crystal and deposited film.
Atomfair's Lanthanum (La) evaporation pellets (99.99%, 1-10 mm) provide high-purity material for thin-film deposition, but require source compatibility verification and Z-Ratio calibration for reliable operation.
Positive
- High purity and defined pellet form: 99.99% purity and 1-10 mm pellet size ensure consistent evaporation behavior and uniform film deposition in vacuum processes.
- Multiple evaporation source compatibility: Compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner, offering flexibility for different deposition systems.
Trade-offs
- Deposition source compatibility required: The material's melting point (921°C) and pellet form necessitate careful matching with boat/liner materials and source geometry to avoid contamination or process failure.
- Z-Ratio calibration needed: The specified Z-Ratio of 0.92 must be input into quartz crystal microbalance controllers for accurate deposition rate and film thickness monitoring.
