This material requires thermal evaporation using a refractory metal boat or ceramic crucible to avoid contamination. The deposition process must account for the material's melting point of 649°C and a Z-ratio of 1.61 for accurate thickness monitoring.
- Evaporation Source Material: Use Mo, W, or Ta boats or graphite/alumina crucibles to prevent alloying or reaction with molten magnesium.
- Deposition Method: Thermal resistive evaporation is preferred; low-power e-beam is optional but may require careful power control.
- Source Geometry Matching: Confirm that the pellet size of 1-3 mm is compatible with the source pocket dimensions to ensure proper loading.
- Melting Point Control: Control the evaporation temperature around the melting point of 649°C to achieve consistent vaporization rates.
- Thickness Calibration: Set the quartz crystal microbalance to the Z-ratio of 1.61 for accurate film thickness monitoring.
What is the melting point of the Mg pellets and how does it influence the recommended evaporation method?
The melting point is 649°C. This relatively low melting point makes thermal/resistive evaporation the preferred method, as it can be achieved with standard resistive heating or low-power e-beam using Mo, W, or Ta boats or graphite/alumina crucibles. The low melting point minimizes source degradation and allows efficient deposition.
What boat or crucible materials are compatible with evaporating these 99.99% magnesium pellets?
Compatible source materials include molybdenum (Mo), tungsten (W), and tantalum (Ta) boats, as well as graphite or alumina crucibles. These materials are specified to withstand the melting temperature of Mg (649°C) and are recommended to avoid contamination during evaporation.
How does the 1-3 mm pellet size affect loading and evaporation performance?
The 1-3 mm pellet size is designed to support reliable source loading into boats or crucibles and promote consistent evaporation rates during deposition.
This evaluation covers Atomfair Magnesium (Mg) Evaporation Material (99.99% purity, 1-3 mm pellets) for thermal/e-beam deposition. The material's defined purity, pellet form, and source compatibility data support informed process integration, though the low melting point and preferred thermal evaporation method impose operational constraints.
Positive
- High purity and defined pellet size: Specified at 99.99% purity with 1-3 mm pellet form, enabling consistent evaporation behavior and reproducible thin-film deposition.
- Compatible with multiple evaporation sources: Compatible with Mo/W/Ta boats and graphite/alumina crucibles for thermal/resistive evaporation, with low-power e-beam as an optional method, providing flexibility in source selection.
Trade-offs
- Low melting point requires careful thermal control: With a melting point of 649°C and density of 1.74 g/cm³, the material may evaporate rapidly, demanding precise temperature management to avoid splattering or non-uniform films.
- Pellet form limits e-beam source compatibility: The 1-3 mm pellet size is primarily suited for thermal evaporation; low-power e-beam is only optional, and users must confirm source geometry compatibility.
