This iridium evaporation material requires water-cooled copper e-beam hearth and compatible liner materials (graphite, Al2O3, BN, or Ta) for deposition. The high melting point of 2410°C and density of 22.42 g/cm³ necessitate appropriate source power and thickness monitoring using the Z-ratio of 0.129.
- Evaporation Source Compatibility: Use only with water-cooled copper e-beam hearth and liners made of graphite, Al2O3, BN, or Ta to avoid contamination or damage.
- Deposition Parameter Matching: Match the evaporation source power to the material's melting point of 2410°C and density of 22.42 g/cm³ for stable deposition.
- Thickness Monitoring: Calibrate the quartz crystal monitor using the Z-ratio of 0.129 to ensure accurate film thickness measurement.
- Material Handling: Handle iridium pieces with clean tools to avoid contamination that could affect film purity.
- Pre-Deposition Verification: Confirm the material purity (99.95%) and piece size (3-6 mm) match the source crucible and process requirements.
What is the significance of the Z-ratio of 0.129 for Iridium (Ir) evaporation material in e-beam deposition?
The Z-ratio of 0.129 is a material-specific parameter used in quartz crystal microbalance (QCM) monitoring to correct for the acoustic impedance mismatch between Iridium and the quartz crystal, enabling accurate film thickness measurement and deposition rate control. This value is explicitly listed in the product specifications for this 99.95% pure Iridium evaporation material.
What liner materials are compatible with Iridium evaporation in e-beam systems?
The compatible liner materials for Iridium evaporation are graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum). The product specifies a water-cooled copper e-beam hearth as the primary evaporation source, with these liners listed as compatible options for containing the Iridium pieces (3-6 mm size) during deposition.
How does the high melting point of Iridium (2410°C) influence the required evaporation method and source configuration?
The melting point of Iridium is 2,410°C, which necessitates e-beam evaporation as the preferred method because it can achieve the high temperatures required for vaporization. The product specifies a water-cooled copper e-beam hearth as the compatible evaporation source, which prevents melt contamination and thermal damage to the crucible while handling the high-density (22.42 g/cm³) material.
Iridium (Ir) evaporation material in piece form (3-6 mm, 99.95% purity) is evaluated for E-beam deposition. Its high melting point and density demand careful process control, while compatibility with multiple liner materials provides flexibility for thin-film applications.
Positive
- High purity and defined form: 99.95% purity and uniform 3-6 mm pieces ensure consistent evaporation behavior and reliable film stoichiometry for research-grade thin-film deposition.
- Flexible liner compatibility: Compatible with water-cooled copper e-beam hearth and graphite/Al2O3/BN/Ta liners, allowing adaptation to various evaporation source configurations without requiring custom hardware.
Trade-offs
- High melting point requires high-power E-beam: Melting point of 2,410°C necessitates high-energy e-beam evaporation systems, limiting use with lower-power thermal sources and increasing infrastructure demands.
- High density and low Z-ratio complicate rate control: Density of 22.42 g/cm³ and Z-ratio of 0.129 require careful calibration of quartz crystal microbalance (QCM) thickness monitors and deposition rate feedback to avoid film thickness errors.
