Iridium evaporation pellets require e-beam deposition with a water-cooled copper hearth and compatible liners. The material's high melting point (2410°C) and density (22.42 g/cm³) demand precise power control and source configuration.
- Deposition Method: E-beam evaporation is the preferred method for this material.
- Source Compatibility: Compatible with water-cooled copper e-beam hearth and graphite, Al2O3, BN, or Ta liner materials.
- Melting Point: Melting point of 2410°C requires sufficient electron beam power and thermal management.
- Density: Density of 22.42 g/cm³ must be considered for material loading and source capacity.
- Z-Ratio: Z-ratio of 0.129 affects quartz crystal microbalance thickness monitoring calibration.
How does the Z-ratio of 0.129 impact thickness monitoring accuracy during e-beam evaporation of iridium pellets?
The Z-ratio of 0.129 indicates the acoustic impedance mismatch between iridium and quartz crystal sensors, requiring proper tooling factor calibration in deposition controllers for accurate film thickness measurement. This value is characteristic of high-density metals like iridium (density 22.42 g/cm³) and must be entered into the monitoring system to compensate for material-specific acoustic properties.
Which liner materials are recommended for e-beam evaporation of iridium pellets given its high melting point?
Compatible liner materials include graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum), as specified for use with a water-cooled copper e-beam hearth. These materials provide thermal stability and chemical inertness at iridium's melting point of 2,410°C to prevent contamination or liner failure during deposition.
Why is e-beam evaporation the preferred method for depositing iridium thin films from pellet form?
E-beam evaporation is preferred due to iridium's high melting point (2,410°C) and density (22.42 g/cm³), which require concentrated electron beam heating for efficient vaporization. The water-cooled copper hearth prevents thermal damage to the source assembly while accommodating the high energy density needed to evaporate this refractory metal.
Iridium (Ir) evaporation pellets at 99.99% purity and 1-3 mm size are optimized for e-beam evaporation with water-cooled copper hearth. The high melting point (2410°C) and density (22.42 g/cm³) require careful process calibration, but the pellet form and multiple pack sizes (1g–100g) support R&D scalability.
Positive
- 99.99% high purity specification: The 99.99% purity grade ensures minimal contamination in deposited thin films, supporting consistent electrical and optical properties for research-grade applications.
- Wide pack size range for R&D: Available in 1g, 5g, 10g, 25g, and 100g packs, allowing incremental material procurement and cost scaling from small experiments to larger deposition runs.
Trade-offs
- Requires specific evaporation hardware: This material is preferred for e-beam evaporation using a water-cooled copper hearth with compatible liners (graphite, Al2O3, BN, or Ta), limiting use to facilities with that exact infrastructure.
- High melting point and density constraints: With a melting point of 2410°C and density of 22.42 g/cm³, the material demands high electron beam power and careful process control to achieve stable evaporation rates.
