Silicon Carbide (SiC) evaporation powder requires E-beam evaporation with a compatible liner or high-temperature crucible. The material's high melting point (~2700°C) and Z-ratio of 1.00 necessitate specific deposition source geometry and process calibration.
- Evaporation Method: E-beam evaporation is the preferred method; thermal evaporation feasibility requires RFQ confirmation.
- Crucible and Liner: A compatible liner or high-temperature crucible must be used to avoid contamination and equipment damage.
- Particle Size: The 790 nm powder size affects source loading density and evaporation rate uniformity.
- Melting Point: The high melting point (~2700°C) requires robust crucible materials and controlled heating protocols.
- Z-Ratio: The Z-ratio of 1.00 simplifies quartz crystal microbalance thickness monitoring calibration.
Why is e-beam evaporation preferred over thermal evaporation for this Silicon Carbide (SiC) powder?
E-beam evaporation is preferred because SiC has a melting point of approximately 2700°C, which exceeds the practical limits of conventional thermal evaporation. Thermal evaporation may be feasible only by RFQ and requires a high-temperature crucible. The material's density of 3.22 g/cm³ and Z-ratio of 1.00 are also specified for e-beam deposition rate monitoring.
What is the significance of the 790 nm particle size for this SiC evaporation material?
The 790 nm powder size is specified to support source loading and consistent evaporation behavior in e-beam hearths. This particle size range ensures uniform deposition and compatibility with the recommended e-beam evaporation hardware. The product is supplied as Powder with 99.5% purity.
What does the Z-ratio of 1.00 indicate for this SiC evaporation material?
The Z-ratio of 1.00 indicates that the acoustic impedance of SiC matches the standard quartz crystal monitor calibration, allowing direct deposition rate monitoring without correction factor adjustments. This is consistent with the specified density of 3.22 g/cm³ and simplifies process control during e-beam evaporation.
Silicon Carbide (SiC) evaporation material in powder form with 99.5% purity and 790 nm particle size, optimized for E-beam evaporation using a compatible hearth liner; its high melting point (~2,700°C) and Z-Ratio of 1.00 simplify process control but require high-temperature crucible hardware and careful source matching.
Positive
- Defined purity and particle size: 99.5% purity and 790 nm powder sizing enable consistent evaporation behavior and film stoichiometry, reducing batch-to-batch variability in thin-film deposition.
- Z-Ratio of 1.00 simplifies monitoring: A Z-Ratio of 1.00 allows direct quartz crystal microbalance (QCM) thickness monitoring without correction factors, streamlining process setup for E-beam evaporation.
Trade-offs
- High melting point requires specialized hardware: With a melting point of ~2,700°C, this material necessitates a high-temperature crucible (by RFQ) and E-beam hearth with compatible liner, limiting compatibility with standard thermal evaporation systems.
- Powder form requires careful handling: The powder form with 790 nm particle size may present dust hazards and requires controlled loading procedures to avoid contamination or loss during source preparation.
