This material is intended for e-beam evaporation under high vacuum and requires a water-cooled copper hearth with a compatible liner (graphite, Al2O3, BN, or Ta) to avoid contamination. The high melting point (2410°C) and density (22.42 g/cm³) demand precise power control and deposition rate monitoring for uniform film growth.
- Compatible Liner Materials: Use a liner of graphite, aluminum oxide, boron nitride, or tantalum to prevent chemical reaction with the molten iridium.
- Vacuum Requirement: Evaporation must be performed in a high-vacuum chamber to achieve the necessary mean free path for deposition.
- Deposition Rate Monitoring: Monitor the deposition rate using a quartz crystal microbalance calibrated with the Z-ratio of 0.129 for accurate thickness control.
- Power Control: Adjust e-beam power incrementally to avoid thermal shock to the pellet and ensure stable evaporation.
What is the recommended evaporation method for Iridium pellets and why are specific liner materials needed?
E-beam evaporation is preferred, using a water-cooled copper e-beam hearth. Compatible liner materials include graphite, Al2O3, BN, or Ta. This is due to iridium's high melting point of 2,410°C and density of 22.42 g/cm³, which require controlled thermal management to prevent crucible contamination.
What liner materials are compatible with Iridium evaporation pellets and how do they affect deposition quality?
Compatible liners are graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum) as stated in the product specification. The source lists these as compatible options but does not provide comparative performance data; selection should be based on the specific deposition system and film requirements.
What purity level is available for Iridium evaporation pellets and how does it impact thin-film applications?
The pellets are supplied at 99.99% purity (4N). This high purity minimizes contamination in vacuum-deposited films, which is critical for applications in semiconductor and photonics where trace impurities can alter electrical or optical properties. The source confirms the purity as 99.99% and the form as 3-6 mm pellets.
Iridium (Ir) evaporation pellets, 99.99% purity, 3-6 mm, are designed for e-beam evaporation in high-vacuum thin-film deposition. The high melting point and density demand appropriate source hardware and liner selection, while the defined form factor ensures consistent deposition.
Positive
- High Purity Iridium Pellets: 99.99% purity ensures minimal contamination in thin-film deposition, critical for applications requiring high-quality iridium films.
- Optimized Pellet Form Factor: Pellets of 3-6 mm size facilitate controlled loading into e-beam evaporation sources, reducing risk of particle ejection and improving uniformity.
Trade-offs
- High Melting Point and Density: Melting point of 2,410°C and density of 22.42 g/cm³ require high-energy e-beam systems and careful handling; the material's weight may affect source stability.
- Liner Compatibility Required: Compatible with water-cooled copper hearth and specific liners (graphite, Al2O3, BN, Ta); incorrect liner choice may lead to contamination or poor thermal contact.
