This evaporation material is intended for vacuum thin-film deposition using e-beam evaporation as the primary method. Successful deposition requires matching the material's thermal properties and physical form to the specific evaporation source hardware and process parameters.
- Deposition Source Compatibility: Use only with water-cooled e-beam hearth or W/Ta support by RFQ, and restrict thermal evaporation to thin charge or qualified setups only.
- Process Matching Requirements: Match evaporation source hardware and process route to the material's melting point, density, and Z-ratio to ensure uniform film deposition.
- Pre-Order Confirmation: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before placing an order.
- Documentation Review: Review certificate, safety data sheet, shipment conditions, and export requirements against laboratory use requirements before handling.
What is the Z-ratio of 0.257 for molybdenum and why is it important for e-beam evaporation process control?
The Z-ratio of 0.257 for molybdenum is a material-specific parameter used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the crystal and the deposited film. This value must be entered into the deposition controller to ensure accurate film thickness measurement during e-beam evaporation.
Can this molybdenum wire be used in thermal evaporation systems, or is it strictly for e-beam evaporation?
E-beam evaporation is the preferred method for this molybdenum wire due to its high melting point of 2,617°C. Thermal evaporation is only recommended for thin charges or qualified setups, as the high temperature required may exceed the capabilities of standard thermal sources. Buyers should confirm their deposition source geometry and compatibility.
What deposition source hardware is required to evaporate molybdenum wire effectively?
The recommended deposition source configuration for molybdenum wire is a water-cooled e-beam hearth or a tungsten/tantalum (W/Ta) support by RFQ (request for quotation). The water-cooled hearth prevents thermal damage to the source, while W/Ta supports can be used for custom setups.
Molybdenum wire (99.95%, 2.0 mm diameter) is specified for e-beam evaporation, with thermal evaporation restricted to thin charge setups; buyers must confirm deposition source compatibility and may require RFQ for W/Ta support.
Positive
- 99.95% purity for consistent films: The 99.95% material specification provides a well-defined purity baseline for standard evaporation processes, reducing batch-to-batch variability in thin-film composition.
- Precise wire form and diameter: Supplied as 2.0 mm diameter wire, enabling controlled loading into e-beam hearths or thermal sources and simplifying geometry matching for deposition hardware.
Trade-offs
- Thermal evaporation limited: Thermal evaporation is only recommended for thin charge or qualified setups; standard use requires e-beam evaporation, which may restrict available deposition equipment.
- Source compatibility via RFQ: For water-cooled e-beam hearths or W/Ta supports, compatibility must be confirmed by quotation, adding a procurement step to verify source geometry before ordering.
