Atomic Layer Deposition System(FlexAL ALD)@remote plasma

Remote plasma & thermal ALD in one flexible tool

The FlexAL® systems provide a new range of flexibility and capability in the engineering of nanoscale structures and devices by offering remote plasma atomic layer deposition (ALD) processes and thermal ALD within a single ALD system.

The FlexAL system delivers:

  • Maximum flexibility in the choice of materials and precursors
  • Low-temperature processes enabled by plasma ALD
  • Low damage maintained by the use of remote plasma
  • Controllable, repeatable processes via recipe-driven software interface
  • Can be configured for both R&D and Production environments

    FlexAL System Benefits:

  • Ability to handle from small wafer pieces up to full 200mm wafers
  • Load-locked wafer entry for low particle count and short loading-to-process-start time
  • Integral glove box on precursor modules for in-situ change-over
  • Integral ports to allow the addition of in-situ ellipsometry measurement tools
  • May be integrated in cluster system with other process tools, including Oxford Instruments PlasmaPro 100 range of etch and deposition tools

  • Key Features

  • Remote plasma & thermal ALD in one flexible tool
  • Automated 200mm load lock for process flexibility
  • Clusterable for vacuum transfer of substrates
  • Cassette to cassette handling increases throughput suitable for production
  • Hex handler with robot and 25 wafer cassette for 100mm, 150mm or 200mm wafers (no tools required to swap between wafers)
  • All configurations can be located entirely within the cleanroom or through-the-wall
