This gold wire evaporation material requires precise matching of evaporation source geometry and process parameters. The Z-ratio and melting point must be incorporated into deposition system calibration and thermal management.
- Evaporation Source Compatibility: The wire diameter of 1.0 mm must be compatible with the selected W/Mo/Ta filament, basket, coil, or boat geometry to ensure uniform loading and evaporation.
- Thickness Monitoring Calibration: The Z-ratio of 0.381 must be entered into the quartz crystal monitor for accurate film thickness measurement during thermal evaporation.
- Thermal Process Requirements: The evaporation source must reach and maintain a temperature of 1064°C under vacuum to achieve the melting point of gold for vaporization.
How does the Z-ratio of 0.381 for gold evaporation wire influence the accuracy of quartz crystal microbalance (QCM) thickness monitoring during thermal evaporation?
The Z-ratio of 0.381 is a material-specific acoustic impedance factor used to correct QCM readings for the viscoelastic properties of gold. This value is required for precise film thickness control, especially when depositing gold at 99.999% purity. The specified Z-ratio ensures that the QCM tooling factor is calibrated correctly for gold wire with a density of 19.32 g/cm³ and melting point of 1,064°C, as provided in the technical specifications.
Is this gold wire (1.0 mm diameter, 99.999% purity) compatible with both tungsten (W) and molybdenum (Mo) evaporation sources, and are there any constraints on source geometry?
Yes, this gold wire is explicitly specified for thermal/resistive evaporation using W, Mo, or Ta filament, basket, coil, or boat sources. The 1.0 mm wire diameter is designed to fit into standard filament coils and boat crucibles. Precautions should be taken to ensure the wire is cut to appropriate lengths for the specific source geometry to avoid uneven heating or splattering.
What are the implications of the 1,064°C melting point for gold wire in thermal evaporation, and does the wire require pre-melting or wetting before deposition?
The melting point of 1,064°C indicates that gold melts at a relatively low temperature compared to many refractory metals, allowing for efficient thermal evaporation. For wire form, pre-melting on the source is often recommended to achieve a uniform melt pool and consistent evaporation rate. The technical specification does not prescribe a specific pre-melting procedure, but users should monitor the melt behavior and adjust power gradually to avoid thermal shock.
Gold (Au) evaporation wire at 99.999% purity and 1.0 mm diameter offers high material quality for thermal evaporation, but requires careful source hardware matching and contamination-free handling.
Positive
- High Purity 99.999% Gold: Ensures minimal contamination in thin-film deposition for sensitive applications such as semiconductor, photonics, or advanced materials research.
- Defined Wire Form and Diameter: Wire form with 1.0 mm diameter facilitates consistent loading and evaporation in thermal sources using W/Mo/Ta filaments, baskets, coils, or boats.
Trade-offs
- Source Hardware Compatibility Required: The wire must be matched to specific evaporation source geometry and filament material; improper selection may lead to uneven deposition or source damage.
- High Purity Handling Sensitivity: The 99.999% purity demands careful handling and storage to avoid surface contamination, often requiring cleanroom or glovebox conditions for optimal film quality.
