The Arradiance Gemstar atomic layer deposition (ALD) system supports thermal ALD coating processes with precise ultrathin and pinhole free films in a compact benchtop platform. The system deposits films with thicknesses ranging from one atomic layer to several nanometers on a variety of substrate materials and can accommodate substrates ranging from small pieces to 200 mm diameter wafers. Standard processes include Titanium Oxide and Hafnium Oxide.

Specifications/Capabilities

  • Precisely controlled ultrathin and pinhole free film coating.
  • Film thicknesses ranging from one atomic layer to tens of nanometers.
  • Maximum temperature: 200 °C.
  • Standard deposition processes:
    • Titanium Oxide.
    • Hafnium Oxide.
