This evaporation material requires E-beam deposition with a water-cooled copper hearth or compatible liner. Source geometry and process parameters must match the material's melting point of 2,617°C and density of 10.2 g/cm³.
- Deposition Method Preference: E-beam evaporation is the preferred deposition method for this material.
- Source Compatibility: Use a water-cooled copper e-beam hearth or compatible liners made of graphite, Al2O3, BN, or Ta.
- Process Matching: Match the evaporation source hardware and process route to the material's melting point, density, and Z-ratio for optimal film quality.
- Pre-Quotation Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before ordering.
- Documentation Review: Review the certificate of analysis, safety data sheet, shipment conditions, and export requirements for laboratory compliance.
What is the significance of the Z-ratio of 0.257 for molybdenum evaporation material in e-beam deposition?
The Z-ratio (0.257) is a material-specific parameter used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness monitoring during e-beam evaporation. A lower Z-ratio indicates a higher acoustic impedance mismatch, requiring proper tooling factor adjustment to avoid thickness errors. This value is critical for process control when depositing Mo films.
Which liner materials are compatible with molybdenum evaporation in a water-cooled copper e-beam hearth?
Compatible liner materials include graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum). These liners provide thermal and chemical stability at Mo's high melting point of 2,617°C and prevent contamination of the melt. The choice depends on specific process requirements and liner durability.
Why is e-beam evaporation the preferred method for molybdenum evaporation material?
E-beam evaporation is preferred because molybdenum has a very high melting point (2,617°C) which requires localized heating to avoid thermal damage to the crucible or hearth. The water-cooled copper hearth with compatible liners allows controlled evaporation without melting the entire crucible, ensuring high-purity film deposition.
Molybdenum (Mo) evaporation material in piece form with 99.99% purity and 3–6 mm size range is specified for e-beam evaporation using water-cooled copper hearths and compatible liners. The high melting point (2,617°C) and Z-ratio (0.257) impose operational constraints on power requirements and deposition rate control.
Positive
- High purity for consistent films: 99.99% purity minimizes contamination in thin-film deposition, enabling reproducible electrical and optical properties in Mo layers.
- Defined piece size for source loading: Pieces sized 3–6 mm provide a controlled geometry for consistent loading into e-beam crucibles and liners, reducing bridging or spitting risks.
Trade-offs
- High melting point requires high power: Melting point of 2,617°C demands high-power e-beam sources and careful thermal management to avoid hearth damage or incomplete evaporation.
- Z-ratio affects rate monitoring accuracy: A Z-ratio of 0.257 requires calibration of quartz crystal monitors for accurate thickness measurement, adding complexity to process setup.
