This material requires specific evaporation source hardware, including an E-beam hearth with a compatible liner or a high-temperature crucible by RFQ, to process the 20–35 nm pieces. The listed melting point, density, and Z-ratio must be verified against the deposition system's capabilities to avoid equipment damage or film defects.
- Source Compatibility: Use an E-beam hearth with a compatible liner or request a high-temperature crucible via RFQ for thermal evaporation.
- Evaporation Method: Confirm that E-beam evaporation is available or request a feasibility quote for thermal evaporation.
- Material Properties: The melting point, density, and Z-ratio must be cross-checked with the deposition system's parameters to ensure proper evaporation.
- Procurement Verification: Verify the material model, purity, form, size range, and pack size against the deposition source requirements before ordering.
- Documentation Review: Review the certificate of analysis, safety data sheet, and shipment conditions to confirm compliance with laboratory handling protocols.
What is the Z-ratio of 1.00 for this Si3N4 evaporation material and why does it matter for thin-film deposition monitoring?
The Z-ratio is listed as 1.00, indicating that Silicon Nitride has the same acoustic impedance as the quartz crystal sensor, simplifying thickness monitoring during e-beam evaporation. This eliminates the need for a tooling factor adjustment, making it a straightforward material for process control. The Z-ratio value is a key parameter for accurate film thickness measurement in vacuum deposition systems.
Is this Si3N4 evaporation material compatible with thermal evaporation or only e-beam evaporation?
E-beam evaporation is the preferred method for this Silicon Nitride material, as stated in the product specifications. Thermal evaporation may be feasible but requires a request for quotation (RFQ) to confirm hardware compatibility. The material requires an e-beam hearth with a compatible liner or a high-temperature crucible by RFQ, reflecting its high melting point of 1,900°C.
What crucible or liner material is required to handle the high melting point of Si3N4 during evaporation?
The product specifies that a high-temperature crucible is required, available by RFQ, and an e-beam hearth with a compatible liner is standard. Given the melting point of 1,900°C, standard crucibles may not be suitable, and buyers should confirm hardware compatibility before ordering. The density of 3.44 g/cm³ also influences hearth loading and material behavior during evaporation.
Silicon Nitride (Si3N4) evaporation material in pieces (20-35 nm, 99.6% purity) is optimized for E-beam evaporation using a compatible liner or high-temperature crucible, with a melting point of 1,900°C and density of 3.44 g/cm³, requiring careful source geometry and thermal feasibility confirmation before deployment.
Positive
- High-purity Si3N4 for thin-film deposition: The 99.6% purity and defined particle size range (20-35 nm pieces) enable consistent evaporation behavior and film stoichiometry for research-grade vacuum deposition workflows.
- Multiple pack sizes for scalability: Available in 25g, 100g, 500g, and 1kg packs, allowing researchers to match quantity to experimental scale without over-procurement.
Trade-offs
- E-beam evaporation preferred; thermal limited: The material is specified for E-beam evaporation with a compatible liner; thermal evaporation requires a feasibility RFQ, adding process validation steps for alternative methods.
- High melting point requires robust hardware: With a melting point of 1,900°C, the material demands high-temperature crucibles or specialized hearth liners, increasing infrastructure and compatibility checks before use.
