This evaporation material requires thermal or resistive evaporation with low-power e-beam as an optional method using molybdenum, tungsten, or tantalum boats or graphite/alumina crucibles. Deposition source geometry and process parameters must be matched to the material's melting point, density, and Z-ratio to ensure film quality and avoid source contamination.
- Evaporation Source Compatibility: Use a molybdenum, tungsten, or tantalum boat or a graphite or alumina crucible for thermal resistive evaporation or low-power e-beam deposition.
- Process Parameter Matching: Adjust deposition parameters according to the material's melting point of 328°C, density of 11.34 g/cm³, and Z-ratio of 1.13.
- Pack Size Selection: Select the required pack size from the available options of 100g, 500g, or 1kg based on the deposition run requirements.
- Documentation Review: Review the certificate of analysis and safety data sheet to confirm material purity and handling precautions before use.
- Deposition Source Loading: Load the lead shots into the evaporation source boat or crucible, ensuring uniform distribution for consistent evaporation.
What is the recommended evaporation method for lead shot with a melting point of 328°C, and what crucible materials are compatible?
Thermal/resistive evaporation is preferred; low-power e-beam is optional. Compatible source materials include Mo/W/Ta boats or graphite/alumina crucibles. The low melting point (328°C) allows efficient thermal evaporation with minimal power.
How does the Z-ratio of 1.13 affect thickness monitoring during lead thin-film deposition?
The Z-ratio of 1.13 is used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness measurement. This value corrects for the acoustic impedance mismatch between lead and the quartz crystal, ensuring precise deposition control.
What purity level is specified for this lead evaporation material, and how does it impact thin-film quality?
The material is specified at 99.99% purity (4N), which minimizes contamination in deposited films. This high purity is critical for applications requiring consistent electrical or optical properties in lead thin films.
This lead shot material (99.99% purity, 1–3 mm) is suitable for thermal evaporation in Mo/W/Ta boats or graphite/alumina crucibles, with a melting point of 328°C and density of 11.34 g/cm³, requiring careful handling due to lead's toxicity.
Positive
- High purity 99.99%: The 99.99% purity specification ensures minimal contamination in thin-film deposition, critical for research-grade applications.
- Optimized shot size for evaporation: The 1–3 mm shot size facilitates efficient loading and uniform evaporation in thermal/resistive sources, reducing the risk of source bridging.
Trade-offs
- Toxic material handling required: Lead is a toxic heavy metal; users must implement proper fume extraction, personal protective equipment, and hazardous waste disposal protocols.
- Limited evaporation method compatibility: The material is optimized for thermal/resistive evaporation; low-power e-beam is optional but may require careful tuning to avoid splattering or incomplete melting.
