This SiO2 evaporation powder requires deposition-source compatibility confirmation before use. Evaporation method and hardware must be matched to the material's melting point and film specifications.
- Deposition-Source Compatibility: Confirm that the E-beam hearth uses a graphite, Al2O3, or BN liner, or that the boat is made of W, Mo, or Ta, as specified in the product documentation.
- Process Route Matching: Match the evaporation method and hardware to the material's melting point, density, and required film properties.
- Documentation Verification: Review the certificate of analysis, safety data sheet, and shipment conditions against laboratory requirements before procurement.
What is the significance of the Z-ratio of 1.00 for SiO2 powder in e-beam evaporation and how does it affect film thickness monitoring?
The Z-ratio of 1.00 indicates that the acoustic impedance of SiO2 matches the quartz crystal sensor, eliminating the need for a correction factor in quartz crystal microbalance (QCM) thickness monitoring. This simplifies process calibration and improves deposition accuracy for e-beam evaporation of this 99.99% purity powder.
What liner or boat materials are recommended for e-beam evaporation of this SiO2 powder to avoid contamination?
The product specification recommends an e-beam hearth with graphite, alumina (Al2O3), or boron nitride (BN) liner, or a tungsten (W), molybdenum (Mo), or tantalum (Ta) boat. Additionally, tantalum and graphite are listed as sheet2 hardware options, and Al2O3 is also noted, providing flexibility for different deposition systems.
What is the preferred evaporation method for this SiO2 powder, and can thermal evaporation be used?
E-beam evaporation is the preferred method, rated as 'Excellent' for this material. Thermal evaporation is available by request for quotation (RFQ), allowing users to explore alternative deposition routes if e-beam hardware is not accessible.
Silicon(IV) Oxide (SiO2) evaporation material in powder form with 99.99% purity and 1-5 µm particle size is evaluated for E-beam evaporation, offering excellent performance with graphite/Al2O3/BN liners or W/Mo/Ta boats, though thermal evaporation requires RFQ confirmation.
Positive
- High purity for thin-film consistency: 99.99% purity specification supports reproducible film stoichiometry and reduces contamination risk in sensitive optical or dielectric layer deposition.
- Defined particle size for source loading: Powder form with 1-5 µm sizing facilitates uniform evaporation source packing and consistent vapor flux in E-beam hearths with graphite/Al2O3/BN liners or W/Mo/Ta boats.
Trade-offs
- Thermal evaporation requires RFQ: Thermal evaporation is not directly supported and requires a request-for-quotation (RFQ) process, adding lead time and confirmation steps for alternative deposition routes.
- Infrastructure dependency for E-beam use: Optimal performance relies on specific E-beam hearth liners (graphite, Al2O3, BN) or metal boats (W, Mo, Ta), requiring users to verify compatibility with existing deposition hardware before ordering.
