Gold wire for thermal evaporation requires compatibility with W/Mo/Ta filament, basket, coil, or boat sources. The material's melting point of 1064 °C and Z-ratio of 0.381 must be considered for deposition rate monitoring.
- Source Material Compatibility: The evaporation source must be made of tungsten, molybdenum, or tantalum to withstand the gold melting point without contamination.
- Melting Point Requirement: The deposition system must reach and maintain a temperature of at least 1064 °C to vaporize the gold wire.
- Purity Specification: The 99.999% purity level ensures minimal impurity incorporation into deposited films.
- Wire Diameter Constraint: The 0.5 mm wire diameter must be compatible with the feed mechanism or source holder geometry.
- Deposition Method Requirement: Thermal evaporation under vacuum is the intended technique; other methods may require process revalidation.
This procedure outlines the steps to confirm and prepare gold wire for thermal evaporation. Following these steps ensures material compatibility and process reproducibility.
Required Equipment: Thermal evaporator with W/Mo/Ta source
- Verify Material Specifications
Confirm the gold wire purity, form, and diameter match the deposition requirements and source geometry. - Review Documentation
Review the certificate of analysis, safety data sheet, and shipment conditions for handling and storage guidelines. - Select Evaporation Source
Choose a tungsten, molybdenum, or tantalum source that can accommodate the wire diameter and withstand the melting point. - Confirm Source Compatibility
Match the deposition source hardware and process route to the material's melting point, density, and Z-ratio for accurate rate monitoring.
Why is the Z-ratio of 0.381 important when using this gold wire in thermal evaporation?
The Z-ratio of 0.381 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring. It accounts for the acoustic impedance mismatch between gold and the quartz crystal, directly affecting the accuracy of film thickness and deposition rate measurements. This value is specific to 99.999% pure gold and must be programmed into the deposition controller to achieve precise control over thin-film properties.
What evaporation source types are compatible with this 0.5 mm diameter gold wire?
This 0.5 mm gold wire is compatible with W/Mo/Ta filament, basket, coil, or boat sources used in thermal/resistive evaporation. The wire diameter is designed to fit standard source geometries, ensuring reliable loading and consistent evaporation. Buyers should verify that their source clamps or feeders can accommodate 0.5 mm wire before ordering.
How do the melting point (1,064 °C) and density (19.32 g/cm³) affect handling and process parameters for this gold evaporation material?
The melting point of 1,064 °C indicates moderate heating requirements, compatible with standard thermal evaporation sources. The high density of 19.32 g/cm³ means that even a 1 g pack provides limited volume, making pack size selection critical for deposition run duration. These properties also influence material behavior in the crucible, requiring careful temperature ramping to avoid spitting and ensure uniform film growth.
This gold wire evaporation material (99.999% purity, 0.5 mm diameter) is designed for thermal resistive evaporation using standard W/Mo/Ta sources, with a melting point of 1064°C and a Z-ratio of 0.381 for process monitoring.
Positive
- High-purity wire form: At 99.999% purity and 0.5 mm diameter, this wire form ensures consistent evaporation rates and minimal contamination in thin-film deposition.
- Broad source compatibility: Compatible with W/Mo/Ta filament, basket, coil, or boat sources, this material integrates into existing thermal evaporation systems without hardware modification.
Trade-offs
- Source geometry verification required: Buyers must confirm that the 0.5 mm wire diameter matches their deposition source geometry and loading mechanism to avoid process interruptions.
- Handling and documentation prerequisites: The material requires careful handling to avoid surface contamination, and certificate of analysis, safety data sheet, and shipment conditions must be reviewed before ordering.
