Indium evaporation material requires vacuum deposition with source materials limited to molybdenum, tungsten, tantalum, graphite, or alumina to prevent chemical reaction. The low melting point (157°C) and Z-ratio (0.841) demand precise temperature control and quartz crystal monitor calibration for uniform film deposition.
- Source Material Compatibility: Use only molybdenum, tungsten, tantalum boats or graphite, alumina crucibles to avoid alloying or reaction with indium.
- Evaporation Temperature Control: Maintain precise temperature control around the melting point of 157°C to prevent spitting and ensure stable evaporation.
- Shot Loading: Load the 1-3 mm shot uniformly into the source to avoid bridging and ensure complete melting.
- Thickness Monitor Calibration: Calibrate the quartz crystal monitor using the Z-ratio of 0.841 for accurate film thickness measurement.
Why is thermal/resistive evaporation preferred over e-beam for indium shot, and what boat or crucible materials are compatible?
Thermal/resistive evaporation is preferred for indium due to its low melting point of 157°C, which allows efficient vaporization without the high-energy electron beam that can cause spitting or contamination. Compatible source materials include molybdenum, tungsten, or tantalum boats, as well as graphite or alumina crucibles, as specified in the product description.
What is the significance of the Z-Ratio of 0.841 for indium in quartz crystal monitoring during thin-film deposition?
The Z-Ratio of 0.841 is a critical parameter for calibrating quartz crystal microbalance (QCM) sensors used to monitor film thickness during deposition. It corrects for the acoustic impedance mismatch between indium and the quartz crystal, enabling accurate measurement of deposition rate and final film thickness as stated in the technical specifications.
How does the 1-3 mm shot size of indium affect loading into deposition sources and evaporation uniformity?
The 1-3 mm shot size is designed for convenient loading into boats or crucibles without pre-melting, promoting even heating and consistent evaporation rates. The product description specifies that buyers should confirm deposition source geometry compatibility, and the shot form is intended to support source loading and evaporation review, reducing the risk of spitting or non-uniform film deposition.
This Indium (In) evaporation material (99.999% purity, shot 1-3 mm) is suitable for thermal or resistive evaporation in vacuum thin-film deposition, with a low melting point (157°C) and density of 7.3 g/cm³, requiring careful process control and Z-ratio calibration for accurate film thickness monitoring.
Positive
- High purity (99.999%): Minimizes contamination in deposited thin films, critical for reproducible electronic or optical properties.
- Defined shot form (1-3 mm): Consistent particle size enables uniform loading and stable evaporation from standard Mo/W/Ta boats or alumina crucibles.
Trade-offs
- Low melting point (157°C): Requires careful thermal management and compatible source hardware to avoid uncontrolled evaporation, spitting, or premature release.
- Z-ratio calibration needed: The Z-ratio of 0.841 must be entered into the deposition controller for accurate quartz crystal microbalance film thickness monitoring.
