R D Mathis Alumina coated evaporation sources
Examples of
Alumina coated
evaporation boat sourcesAlumina coated evaporation boat sources have been developed to replace alumina crucibles for specific applications. The advantages of the alumina coated boat sources are:
- good heat transfer
- lower power needed compared to crucibles
- inert to most metals or alloys
- no wetting of the alumina coating
- no resistant change when the metal or alloy melts
Due to the non-wetting characteristics of the alumina coating, the evaporant forms a sphere upon melting, resulting in a point source. The lifetime of the alumina coated evaporation sources is longer than the non-coated evaporation boat sources. The alumina coated evaporation sources require some 30-50% more power than the non-coated sources to enable an evaporation process. This is due to the difference in heat conduction.
The alumina coating is semi-conductor grade and is applied to the evaporation source (boat or basket) by a plasma spray technique. The maximum temperature for these sources is 1850°C. When evaporation is effected, the power should be reduced slightly to avoid overheating.
Alumina coated evaporation boat sources are suitable for:
- Materials which would cause wetting of tungsten, tantalum or molybdenum sources
- Thin film thermal evaporation processes for metalising surfaces
- Production cycles with small to large amounts of evaporant
- Medium and high rated power sources
- R & D and product development applications
