Introduction

Alumina 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
