This aluminium wire must be used in thermal/resistive evaporation under vacuum with a compatible tungsten, molybdenum, or tantalum source. The material's melting point of 660°C and Z-ratio of 1.08 require precise process control to avoid film contamination.
- Source Material Compatibility: Only tungsten, molybdenum, or tantalum evaporation sources are compatible with this aluminium wire.
- Vacuum Environment Requirement: The evaporation process must be conducted in a vacuum chamber to achieve thin-film deposition.
- Deposition Geometry Confirmation: Buyers must confirm deposition source geometry and pack size before quotation.
This procedure outlines the key steps for loading and evaporating aluminium wire in a thermal/resistive evaporation system. Follow these steps to ensure proper material handling and deposition consistency.
Required Equipment: Tungsten, molybdenum, or tantalum evaporation source (filament, basket, coil, or boat), Vacuum deposition chamber
- Confirm source compatibility
Confirm the evaporation source material is tungsten, molybdenum, or tantalum to ensure compatibility with the aluminium wire. - Load the wire
Load the aluminium wire into the selected evaporation source, ensuring even distribution for consistent evaporation. - Evacuate and heat
Place the loaded source in the vacuum chamber, evacuate to the required base pressure, then heat the source to the melting point of aluminium (660°C) to initiate evaporation.
What is the impact of the 99.999% purity specification on the performance of aluminium thin films?
The 99.999% purity grade minimizes contamination, reducing impurity levels to below 10 ppm. This is critical for achieving low electrical resistivity and high reflectivity in aluminium thin films, making it suitable for semiconductor metallization and optical coatings.
Which evaporation boat or filament materials are recommended for depositing this aluminium wire?
This aluminium wire is compatible with thermal evaporation sources made of tungsten (W), molybdenum (Mo), or tantalum (Ta) in filament, basket, coil, or boat configurations. These materials can withstand the 660°C melting point of aluminium and provide reliable wetting.
What is the significance of the Z-ratio value of 1.08 for monitoring aluminium deposition thickness?
The Z-ratio of 1.08 is used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the quartz crystal and the deposited aluminium film. This ensures accurate real-time thickness measurement during evaporation.
Atomfair Aluminium Evaporation Material (99.999%, wire, 2.0 mm dia.) is a high-purity pure metal source for thermal resistive evaporation, suitable for W/Mo/Ta filaments. The wire form and defined diameter facilitate repeatable loading, while the 660°C melting point and 2.7 g/cm³ density require process calibration for consistent deposition rates.
Positive
- High Purity (99.999%): Minimizes contamination in deposited thin films, critical for research-grade coatings and reproducible film properties.
- Specified Wire Form and Diameter: Enables reproducible loading into evaporation sources, reducing process variability and improving run-to-run consistency.
Trade-offs
- Low Melting Point (660°C): Requires careful temperature control to avoid overheating or alloying with refractory metal sources; may limit achievable deposition rates for certain applications.
- Z-Ratio of 1.08: Necessitates calibration of quartz crystal monitors for accurate thickness measurement, as the deviation from unity affects frequency-to-thickness conversion.
