Introduction

Tungsten filaments are used extensively for thin film deposition for a wide variety of metals and alloys. Benefits are ease of use, repeatability, low cost, long life, high evaporation rates with low power. They are used for evaporating pieces of metal wire or metal foil which can be inserted into the coils of the filament. Alternatively, thin wire can be wrapped around the coils. The evaporation process involves melting the metal to wet the filaments coils and subsequently increase power to evaporate the molten metal. The evaporation filaments are all made from tungsten wires in various thicknesses.
Available as single stand sources and sources with 3 or 4 strands. They can be used for upwards, sideways evaporation. Downwards evaporation is only advised if the substrate not directly positioned underneath the evaporation filament source. Care needs to be taken when evaporating aluminium with the filaments; aluminium forms an alloy with the tungsten filament, which drastically influences the power requirements. Best to use a new tungsten filament for each evaporation cycle with aluminium. The low cost, Z-shape tungsten filament 72-Z1W3-2.3 has been especially developed for consistent aluminium evaporation. The coiled tungsten evaporation filaments are suitable for:

  • Thin film production processes for metalising surfaces
  • Relatively small amounts of expensive materials
  • R & D and product development applications
  • Sample preparation applications
