This pure indium evaporation material requires specific deposition source hardware and process parameters for optimal film quality. Compatible sources include Mo/W/Ta boats or graphite/alumina crucibles, with thermal/resistive evaporation preferred over e-beam.
- Source Compatibility: Use only Mo/W/Ta boat or graphite/alumina crucible to avoid contamination or poor evaporation.
- Evaporation Method: Thermal/resistive evaporation is recommended; low-power e-beam is optional but may require parameter adjustment.
- Melting Point Consideration: The material's melting point of 157°C must be accounted for in temperature ramping profiles.
- Density and Z-Ratio: Density of 7.3 g/cm³ and Z-ratio of 0.841 influence deposition rate monitor calibration.
- Physical Form Handling: The shot form (3-6 mm) requires uniform loading to ensure consistent evaporation rate.
Why is Indium supplied as 3–6 mm shot rather than other forms for thermal evaporation, and how does this form factor affect deposition uniformity?
Indium is supplied as 3–6 mm shot to facilitate loading into boats or crucibles and to provide a consistent surface area for evaporation. The specified shot size range supports predictable source loading and uniform evaporation behavior during thermal deposition, which is critical for achieving repeatable film thickness.
What boat or crucible materials are recommended for evaporating Indium shot, and can low-power e-beam be used?
Indium shot is compatible with molybdenum, tungsten, or tantalum boats, as well as graphite or alumina crucibles. Thermal/resistive evaporation is preferred, but low-power e-beam evaporation is also an option with these source materials. The choice depends on the specific deposition system configuration and film requirements.
What is the Z-ratio of Indium (0.841) and why is it important for quartz crystal microbalance (QCM) calibration during thin-film deposition?
The Z-ratio of 0.841 is a material-specific parameter used in quartz crystal microbalance (QCM) monitoring to correct the measured frequency shift for the acoustic impedance of the deposited film. Accurate Z-ratio input ensures the QCM reports the correct film thickness and deposition rate for Indium, preventing errors in process control.
This Indium (In) evaporation material, supplied as 99.999% pure shot in 3–6 mm size, is optimized for thermal or low-power e-beam deposition in Mo/W/Ta boats or alumina/graphite crucibles. Its low melting point (157°C) and Z-ratio (0.841) require careful rate control but enable high-purity films for research applications.
Positive
- High-purity 99.999% specification: The 5N purity level minimizes contamination in deposited thin films, critical for semiconductor and photonics research where trace impurities degrade device performance.
- Consistent shot form and size: The 3–6 mm shot geometry ensures reproducible loading and uniform evaporation behavior across thermal or low-power e-beam sources, reducing run-to-run variability.
Trade-offs
- Low melting point requires thermal control: With a melting point of 157°C, Indium melts rapidly and may cause spitting or uneven flux if power ramping is not carefully managed, demanding precise temperature profiling.
- Low Z-ratio complicates deposition rate monitoring: A Z-ratio of 0.841 is lower than many common metals, requiring recalibration of quartz crystal microbalance sensors to maintain accurate film thickness control during evaporation.
