This alloy evaporation material requires vacuum thin-film deposition equipment with compatible source hardware. Process parameters must account for the material's melting point of 640°C and density of 2.69 g/cm³.
- Source Compatibility: Use Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth for evaporation.
- Evaporation Method: Select thermal/resistive or e-beam evaporation based on material behavior and film requirements.
- Process Monitoring: The Z-Ratio of 1.00 indicates no thickness correction is needed for quartz crystal monitoring.
- Procurement Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before ordering.
- Documentation Review: Review certificate of analysis and safety data sheet for purity and handling requirements.
What is the specified purity and composition of the Al/Si 99/1wt% evaporation material?
The composition is fixed at Al 99 wt% and Si 1 wt%. The total purity is listed as 'RFQ' (request for quotation), meaning the buyer can specify the exact purity grade required during the quotation process. This allows the material to be tailored for applications demanding standard, high-purity, or custom-controlled levels.
What deposition source hardware and methods are compatible with this Al/Si pellet material?
The material is suitable for both thermal/resistive and e-beam evaporation. Compatible source hardware includes Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths. With a melting point of 640°C and density of 2.69 g/cm³, it is well-suited for these deposition methods; sheet hardware options are also available via RFQ.
What is the Z-ratio of this Al/Si alloy and why is it important for deposition monitoring?
The Z-ratio is specified as 1.00. This value is used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the deposited material and the quartz crystal. A Z-ratio of 1.00 indicates that a tooling factor adjustment may be needed for accurate in-situ film thickness control during evaporation.
The Al/Si 99/1 wt% alloy evaporation pellet (3-6 mm) offers a defined binary composition for controlled thin-film deposition, but requires RFQ-based purity confirmation and careful source matching due to its alloy nature and specified evaporation hardware constraints.
Positive
- Defined alloy composition for deposition: The Al 99 wt%, Si 1 wt% composition provides a fixed binary ratio, enabling reproducible film stoichiometry in thermal or e-beam evaporation processes without requiring separate source blending.
- Multiple pack sizes for scalability: Available in 100 g, 500 g, and 1 kg packs, allowing laboratories to match procurement quantity to experimental or pilot-scale deposition runs without over-ordering.
Trade-offs
- Purity requires RFQ confirmation: Total purity is listed as RFQ (request for quotation), meaning the exact impurity profile is not pre-specified; buyers must confirm acceptable purity levels and obtain certificates before ordering for sensitive applications.
- Evaporation source compatibility must be verified: The material is compatible only with Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths using TiB2-BN liners; users must confirm their deposition hardware matches these specified source materials to avoid contamination or process failure.
