Gold pellets require specific deposition source hardware and process parameters for successful thin-film deposition. The material's melting point, density, and Z-ratio must be incorporated into evaporation system calibration and operation.
- Deposition Source Compatibility: Use a molybdenum, tungsten, or tantalum boat for thermal evaporation or a water-cooled e-beam hearth with graphite or alumina liner for e-beam evaporation.
- Evaporation Method Selection: Select either thermal/resistive or e-beam evaporation depending on film purity requirements and deposition rate control.
- Melting Point Consideration: The evaporation source must reach and maintain the 1,064°C melting point of gold for consistent deposition.
- Z-Ratio Calibration: The Z-ratio of 0.381 must be programmed into the thickness monitor for accurate film thickness measurement.
- Pellet Size Compatibility: The pellet size of 1-3 mm must be compatible with the boat or hearth dimensions to ensure proper loading and evaporation.
What is the significance of the Z-ratio of 0.381 for gold evaporation pellets in e-beam deposition?
The Z-ratio of 0.381 is a material-specific parameter used in e-beam evaporation to calibrate the deposition rate monitor, ensuring accurate film thickness control. For gold, this relatively low value indicates a higher tendency for electron reflection, which may require adjustments in sensor calibration. The product's specified Z-ratio allows users to directly input this value into their deposition controller without empirical determination.
Which evaporation source materials and liners are compatible with these 99.99% gold pellets?
The gold pellets are compatible with molybdenum, tungsten, or tantalum boats for thermal evaporation, and with water-cooled e-beam hearths using graphite or alumina liners. These materials are specified to withstand the melting point of 1,064°C and avoid contamination, as gold readily wets and alloys with certain metals. Users must confirm that their deposition source geometry matches the pellet size of 1–3 mm.
What storage and handling considerations are required for 99.99% gold evaporation pellets to maintain purity?
The gold pellets should be stored in a clean, dry environment, preferably in the original sealed container to prevent surface contamination and oxidation. While gold is chemically inert, handling with clean gloves and tools is recommended to avoid introducing impurities that could affect film quality. The product's certificate of analysis should be reviewed to confirm the specified 99.99% purity is maintained upon receipt.
Gold (Au) pellets (99.99%, 1-3 mm) for thermal/e-beam evaporation, compatible with Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners. The defined pellet size and high purity support consistent deposition rates, but the high density (19.32 g/cm³) and melting point (1,064°C) require careful source loading and process validation.
Positive
- High-purity pellet form: 99.99% purity and 1–3 mm pellet size provide consistent evaporation behavior and reduces contamination risk in thin-film deposition.
- Broad source compatibility: Specified for Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners, covering both thermal and e-beam evaporation methods.
Trade-offs
- Pre-order compatibility check required: Buyers must confirm model, purity, form, size, pack size, and deposition-source compatibility before quotation to avoid process mismatch.
- High density and melting point: Density of 19.32 g/cm³ and melting point of 1,064°C demand careful source loading, thermal management, and process parameter tuning to achieve uniform film deposition.
