This evaporation material must be used with a water-cooled e-beam hearth or tungsten/tantalum support for thermal evaporation, and e-beam evaporation is the preferred method. The material's high melting point and Z-ratio require careful calibration of deposition parameters for consistent film quality.
- Evaporation Source Requirement: The wire must be loaded into a water-cooled e-beam hearth or a tungsten/tantalum support for thermal evaporation, and e-beam evaporation is the preferred method for this material.
- Thermal Evaporation Limitation: Thermal evaporation is only acceptable for thin charges or qualified setups, and users should confirm method compatibility with their deposition system.
- Calibration Parameter Influence: The melting point of 2,617°C, density of 10.2 g/cm³, and Z-ratio of 0.257 must be used to calibrate deposition rate and thickness monitoring.
- Physical Form Dimension: The 0.5 mm diameter wire must be verified against the deposition source crucible or feed mechanism for proper loading.
How does the Z-Ratio of 0.257 affect deposition rate monitoring for molybdenum evaporation?
The Z-Ratio of 0.257 must be entered into the quartz crystal microbalance (QCM) thickness monitor to correct for acoustic impedance mismatch between molybdenum and quartz during e-beam evaporation. Using an incorrect Z-Ratio can introduce systematic errors in film thickness measurement; this value is specific to molybdenum at the stated density of 10.2 g/cm³.
What are the recommended evaporation source configurations for this molybdenum wire?
E-beam evaporation is preferred due to molybdenum's high melting point of 2617°C and density of 10.2 g/cm³. Thermal evaporation is only suitable for thin charges in qualified setups using a water-cooled e-beam hearth or tungsten/tantalum support confirmed via RFQ; standard thermal boats may not withstand the required temperatures.
What handling considerations apply when using molybdenum wire with a diameter of 0.5 mm for vacuum deposition?
The wire diameter of exactly 0.5 mm requires careful handling to avoid kinking or surface contamination before loading into the evaporation source. For e-beam systems ensure secure contact with the water-cooled copper hearth; for thermal setups confirm via RFQ that the W/Ta support geometry accommodates this wire size without excessive resistance heating.
This 99.95% pure molybdenum wire (0.5 mm dia.) is evaluated for e-beam evaporation with thermal compatibility only under qualified thin-charge conditions; pre-order confirmation of source geometry and documentation is required for procurement.
Positive
- High purity 99.95% molybdenum wire: The defined material identity and 99.95% purity ensure reproducible thin-film properties and clear procurement matching for vacuum deposition processes.
- Specified physical form for source loading: Wire form with 0.5 mm diameter facilitates consistent loading into e-beam hearths or thermal sources, supporting evaporation review and process control.
Trade-offs
- E-beam evaporation preferred: Thermal evaporation is only recommended for thin charge or qualified setups, limiting direct compatibility with standard thermal evaporators without process validation.
- Pre-order confirmation required: Buyers must confirm deposition source geometry, pack size, certificate, and shipment conditions before quotation, adding procurement lead time.
