This alloy evaporation material requires deposition-source hardware compatibility and process route matching to avoid contamination or film failure. The material's melting point and density must be verified against the evaporation system's operating parameters before use.
- Deposition Source Compatibility: Confirm that the evaporation source hardware (Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth) is compatible with the material's melting point of 640 °C and density of 2.82 g/cm³.
- Purity Verification: Verify that the composition (Al 99 wt%, Cu 1 wt%) and total purity meet the specific film requirements, as purity is provided by RFQ and may vary between batches.
- Physical Form Handling: Handle the pieces (3-6 mm) with care to avoid size segregation or contamination, as the pellet size affects source loading uniformity and evaporation rate.
This procedure outlines the steps to verify material specifications and load the evaporation material into the deposition source. Proper preparation ensures consistent film deposition and minimizes process variability.
Required Equipment: Mo/W/Ta boat or graphite/alumina crucible or e-beam hearth, Vacuum deposition system, Analytical balance
- Verify Material Specifications
Confirm that the material composition (Al 99 wt%, Cu 1 wt%), purity (RFQ), and piece size (3-6 mm) match the deposition process requirements. - Select Deposition Source Hardware
Choose a compatible evaporation source (Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth) based on the material's melting point of 640 °C and the intended evaporation method (thermal/resistive or e-beam). - Weigh Required Quantity
Weigh the appropriate amount of material (e.g., 100g, 500g, or 1kg) using an analytical balance to ensure accurate deposition thickness. - Load Material into Source
Carefully load the pieces into the selected boat, crucible, or hearth, ensuring even distribution to promote uniform evaporation. - Set Deposition Parameters
Configure the vacuum system parameters (e.g., chamber pressure, source current or power) according to the material's Z-ratio of 1.00 and the desired film properties.
What is the significance of the 'total purity RFQ' specification for Al/Cu 99/1wt% evaporation material, and how does it affect film quality?
The 'total purity RFQ' means the overall metallic purity is not fixed but subject to request for quotation, allowing the supplier to adjust purity levels based on customer requirements and budget. This introduces a trade-off between cost and film purity; the base composition is fixed at Al 99 wt% and Cu 1 wt%, but total impurity levels are negotiable. Buyers must confirm purity specifications before quotation to ensure the material meets their deposition process needs.
Which evaporation sources are compatible with Al/Cu 99/1wt% pieces of 3-6 mm size?
The material is compatible with thermal/resistive or e-beam evaporation using Mo/W/Ta boats, graphite or alumina crucibles, or e-beam hearths. The 3-6 mm piece size is designed for loading into these sources, but users must confirm deposition source geometry and hardware compatibility before quotation, as stated in the product documentation. The melting point of 640°C and density of 2.82 g/cm³ should also be considered when matching source type.
What does the Z-ratio of 1.00 indicate for the Al/Cu 99/1wt% evaporation material in thin-film deposition?
The Z-ratio of 1.00 is the tooling factor used for quartz crystal microbalance (QCM) thickness monitoring during evaporation. A value of 1.00 implies that the acoustic impedance of the deposited film is similar to that of the quartz crystal, simplifying thickness calibration. Users should verify whether this default value is accurate for their specific alloy composition and deposition conditions to ensure precise film thickness control.
This Al/Cu 99/1 wt% alloy evaporation material, supplied as 3-6 mm pieces, is specified for thermal/resistive or e-beam evaporation with a melting point of 640°C, density of 2.82 g/cm³, and Z-ratio of 1.00, requiring source-hardware and purity confirmation via RFQ before deposition.
Positive
- Defined alloy composition: The Al 99 wt%, Cu 1 wt% composition provides a clear material identity for matching deposition processes that require controlled copper doping in aluminum films.
- Specified physical form and size: Pieces sized 3-6 mm are suitable for loading into Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths, supporting consistent evaporation source loading.
Trade-offs
- Purity requires RFQ confirmation: Total purity is listed as RFQ, meaning buyers must confirm the exact purity grade and certificate requirements before ordering to ensure it meets application specifications.
- Source compatibility must be verified: Evaporation source hardware (boat, crucible, or e-beam hearth) and process route must be matched to the material's melting point and film requirements, requiring pre-order technical review.
