This document specifies the mandatory equipment and process constraints for using Iridium (Ir) evaporation material in vacuum thin-film deposition. The material requires an e-beam evaporation source with a water-cooled copper hearth and compatible liner materials.
- Evaporation Source Compatibility: The Iridium evaporation material must be used with an e-beam evaporation source employing a water-cooled copper hearth and a liner made of graphite, Al2O3, BN, or Ta.
- Source Geometry Confirmation: Deposition source geometry must be confirmed before ordering to ensure the 1-3 mm pieces fit the source crucible or liner.
- Process Route Matching: The evaporation source hardware and process route must be matched to the material's melting point (2,410°C) and the required film properties.
How does the 99.95% purity of Iridium (Ir) evaporation material affect thin-film quality in e-beam deposition?
The 99.95% purity ensures minimal contamination, making this material suitable for research-grade thin-film applications where film stoichiometry and electrical properties are critical. The specified Pieces 1–3 mm size range supports uniform evaporation from a water-cooled copper e-beam hearth, reducing spitting and source depletion irregularities.
What are the recommended evaporation source and liner materials for Iridium (Ir) evaporation material?
E-beam evaporation is preferred using a water-cooled copper hearth. Compatible liner materials include graphite, Al2O3, BN, or Ta, as stated in the product specifications. The high melting point of 2,410°C requires a high-power e-beam source and careful thermal management to avoid liner degradation.
What is the significance of the Z-ratio (0.129) for Iridium (Ir) evaporation material in quartz crystal microbalance (QCM) monitoring?
The Z-ratio of 0.129 is used to correct the acoustic impedance mismatch between the quartz crystal and the deposited iridium film. This value must be programmed into the deposition controller to ensure accurate thickness monitoring; a Z-ratio far from 1.0 indicates a substantial correction factor, which is typical for high-density metals like iridium (density 22.42 g/cm³).
This Atomfair iridium evaporation material is supplied as 99.95% pieces in 1-3 mm sizing for e-beam deposition in a water-cooled copper hearth with compatible graphite/Al2O3/BN/Ta liners; its reported melting point of 2,410, density of 22.42, and Z-ratio of 0.129 require source-specific process matching before use. Variable pack sizes from 1g to 100g allow the quantity to be matched to the evaporation campaign.
Positive
- Defined 99.95% Iridium Pieces: Supplied as 99.95% iridium in 1-3 mm piece form, providing defined material identity and physical sizing for evaporation source loading and deposition-process matching.
- E-beam Hearth and Liner Compatibility: Specified for water-cooled copper e-beam hearths with graphite, Al2O3, BN, or Ta liner compatibility, which supports source-hardware matching during procurement.
Trade-offs
- High-Melting-Point Processing Constraints: With a reported melting point of 2,410 and density of 22.42, the material requires source hardware and process route matching to accommodate its evaporation behavior, with e-beam evaporation listed as the preferred method.
- Pre-Order Compatibility and Documentation Checks: Deposition source geometry, required quantity, certificate requirements, and shipment conditions must be confirmed before quotation, and certificate, safety data sheet, and export conditions should be reviewed against laboratory use requirements.
