This material requires specific deposition source hardware and process conditions for optimal film formation. Compatibility with E-beam or thermal evaporation systems must be confirmed before use.
- Evaporation Method: E-beam evaporation is the preferred method; thermal evaporation requires RFQ and appropriate boat material selection.
- Source Hardware Compatibility: Recommended liners for E-beam hearth include graphite, Al2O3, or BN; compatible boat materials include W, Mo, or Ta.
- Material Properties: Melting point is 795°C, density is 4.69 g/cm³, and Z-ratio is 1.00, which influence deposition behavior.
- Process Matching: Deposition source geometry and process route must be matched to material behavior, melting point, and film requirements.
- Pre-Use Verification: Confirm model, purity, form, size range, and deposition-source compatibility before quotation and use.
Why is electron-beam evaporation preferred over thermal evaporation for MoO3 pellets?
Electron-beam evaporation is preferred for MoO3 pellets to maintain stoichiometry and avoid decomposition, as thermal evaporation is only available by RFQ and requires specific liner materials such as graphite, Al2O3, or BN in an E-beam hearth, or W/Mo/Ta boats for thermal methods. The product specification explicitly lists E-beam evaporation as the preferred method with thermal evaporation available by special request.
What evaporation source hardware is compatible with 3 mm MoO3 pellets?
For E-beam evaporation, 3 mm MoO3 pellets can be used with a hearth lined with graphite, Al2O3, or BN. For thermal evaporation, compatible boats include W (tungsten), Mo (molybdenum), or Ta (tantalum). The product description provides these compatibility details to assist in deposition-source matching before procurement.
What are the melting point, density, and Z-Ratio of the 99.95% MoO3 pellets, and how do they affect deposition control?
The MoO3 pellets have a melting point of 795°C, a density of 4.69 g/cm³, and a Z-Ratio of 1.00. These values directly influence evaporation power requirements, film density, and quartz crystal monitor calibration. A Z-Ratio of 1.00 simplifies thickness monitoring by eliminating the need for material-specific correction factors during deposition.
This MoO3 pellet evaporation material at 99.95% purity and 3 mm pellet size is specified for e-beam evaporation with thermal evaporation available by RFQ. The listed melting point (795°C), density (4.69 g/cm³), and Z-ratio (1.00) enable direct process matching for thin-film deposition.
Positive
- High purity 99.95%: The 99.95% purity specification supports consistent film stoichiometry and reduces contaminant-related defects in deposited layers.
- Defined pellet size 3 mm: The 3 mm pellet form factor is explicitly sized for controlled source loading and repeatable evaporation in standard e-beam hearths.
Trade-offs
- Non-standard thermal evaporation: Thermal evaporation requires RFQ and is not a standard process route; e-beam evaporation is the preferred method, limiting direct drop-in compatibility.
- Source hardware verification required: Buyers must confirm deposition source geometry, liner material (graphite/Al2O3/BN or W/Mo/Ta boat), and quantity before ordering to ensure physical fit and process compatibility.
