Gold pellets require specific evaporation source hardware such as Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners for thermal or e-beam deposition. The material's melting point of 1064°C, density of 19.32 g/cm³, and Z-ratio of 0.381 must be accounted for in deposition rate control and film uniformity.
- Evaporation Source Compatibility: Use Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners for thermal or e-beam evaporation.
- Evaporation Method: Thermal/resistive or e-beam evaporation under vacuum conditions is required for thin-film deposition.
- Material Properties: The melting point of 1064°C, density of 19.32 g/cm³, and Z-ratio of 0.381 affect deposition rate control and film uniformity.
- Vacuum Environment: A vacuum chamber is necessary to enable evaporation and prevent contamination of the deposited film.
- Pack Size Selection: Select the pack size from 1g to 100g based on the required film thickness and deposition run duration.
How does the 99.99% purity of gold evaporation pellets affect the electrical properties of deposited thin films?
The 99.99% purity minimizes contaminants that could introduce scattering centers or alter resistivity in gold films. This is critical for applications requiring high conductivity, such as electrodes in semiconductor devices. The source specifies this purity grade for research-grade deposition.
What evaporation source configurations are compatible with the 3-6 mm gold pellets?
The pellets are compatible with thermal/resistive evaporation using Mo, W, or Ta boats, and e-beam evaporation using a water-cooled hearth with graphite or alumina liner. The 3-6 mm size ensures uniform loading and consistent melt characteristics across these source types.
What density and Z-ratio values are provided for the gold evaporation material, and why are they necessary for process calibration?
The gold pellets have a density of 19.32 g/cm³ and a Z-ratio of 0.381. These values are essential for calibrating quartz crystal microbalance (QCM) sensors to monitor film thickness accurately during deposition. Without correct Z-ratio, thickness readings can be off by up to 30% for gold.
This Gold (Au) evaporation pellet material (99.99% purity, 3-6 mm pellets) offers a well-defined, research-grade source for high-quality thin-film deposition. The specified pellet size and purity enable consistent evaporation rates, but users must match source hardware (boat or e-beam hearth) and process parameters to the material's high density and melting point.
Positive
- High Purity (99.99%): Minimizes contamination in thin-film deposition, critical for reproducible electrical and optical properties.
- Defined Pellet Form and Size: 3-6 mm pellets facilitate consistent source loading and uniform evaporation rate in both thermal and e-beam systems.
Trade-offs
- Source Compatibility Constraints: Requires specific evaporation source hardware (Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner) and process tuning to avoid material wetting or alloying.
- High Density and Melting Point: Gold's high density (19.32 g/cm³) and melting point (1064°C) demand careful power management and may cause thermal stress in thin boats.
