This powder requires careful selection of evaporation source hardware to avoid contamination and ensure proper deposition. The material is best suited for e-beam evaporation; thermal evaporation requires prior qualification due to potential decomposition or reactivity with boat materials.
- Evaporation Source Liner Compatibility: Load the powder into an e-beam hearth with a graphite, Al2O3, or BN liner, or into a W, Mo, or Ta boat to prevent chemical reaction with the source.
- Preferred Evaporation Method: Use e-beam evaporation as the preferred method; submit a request for quotation if thermal evaporation is required, as it may need process adjustments.
- Melting Point and Source Temperature: The high melting point of 2852°C requires that the evaporation source can reach and maintain this temperature without material degradation.
- Thickness Monitoring Parameter: Set the crystal monitor tooling factor using the Z-ratio of 0.411 to ensure accurate film thickness measurement during deposition.
- Pre-Use Documentation and Compatibility: Review the certificate of analysis, safety data sheet, and shipment conditions to confirm that the material meets laboratory requirements before opening the container.
What is the recommended evaporation method for this MgO powder, and why is e-beam preferred over thermal evaporation?
E-beam evaporation is the preferred method for this MgO powder, with thermal evaporation available by RFQ. The e-beam performance is rated as Good when using a graphite/Al2O3/BN liner or W/Mo/Ta boat. This preference arises from MgO's high melting point of 2,852°C and density of 3.58 g/cm³, which require the high-energy electron beam to achieve efficient vaporization without contamination from boat materials.
Which liner and boat materials are compatible with MgO evaporation in an e-beam hearth?
Compatible liner materials include graphite, Al2O3, and BN for e-beam hearths, and boats made of W, Mo, or Ta. The specification also lists graphite as a Sheet2 hardware option. These materials are selected to withstand MgO's high melting point (2,852°C) and to avoid chemical reaction with the molten oxide during deposition.
What does the Z-ratio of 0.411 indicate for MgO deposition process monitoring?
The Z-ratio of 0.411 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring during thin-film deposition. It corrects the acoustic impedance mismatch between the quartz crystal and the deposited MgO film, enabling accurate real-time measurement of film thickness. This value is specific to MgO and must be entered into the deposition controller to ensure precise process control.
Magnesium Oxide (MgO) evaporation powder (99.5%, 35 nm) offers defined nanoscale morphology for E-beam deposition of high-melting-point dielectric films, but requires specialized evaporation hardware and is not suited for standard thermal evaporation without prior RFQ.
Positive
- Specified nanoscale particle size: The 35 nm powder size enables controlled evaporation rates and consistent film deposition for thin-film applications, as stated in the product specifications.
- E-beam evaporation compatibility: The material is optimized for E-beam evaporation with good performance using graphite, Al2O3, or BN liners, allowing integration into standard deposition systems as noted in the evaporation source details.
Trade-offs
- Restricted evaporation method: Thermal evaporation is only available by RFQ, limiting process flexibility for users without E-beam capability, as explicitly stated in the evaporation method description.
- High melting point requires high power: With a melting point of 2852°C, this material demands high-energy E-beam sources and compatible hearth liners, increasing operational constraints and hardware requirements.
