new VCD tool prototype

The Depositron

VCD is

a new patented technology to make a thin film coating of any material

  • VCD is a vacuum plasma technology similar to PLD- but uses a powerful e-beam instead of a laser
  • Virtual plasma cathode is the heart of VCD - it generates an e-beam of >1kA@20keV focused to <1mm on the target

Depositron Solo parameters

Benefits of VCD

Deposition temperature <60ᵒC due to short pulse duration

High deposition rate due to high pulse energy/repetition rate

High quality of film (same as PLD’s or better)

Industrialisation (Simplicity, reliability & scalability)

Virtual Plasma Cathode is the electron beam source of the Depositron

Virtual Plasma Cathode – originates from a plasma that temporarily appears in front of the target, generates an e-beam and then disappears for each pulse. So it:

  • has practically infinite lifetime
  • is easy-to-scale for extremely high pulse power and repetition rate
  • is highly efficient and reliable
