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.

Usage Information

Supported Sample Sizes

  • Maximum wafer diameter: 200 mm.
  • Small pieces supported: Yes.

Typical Applications

  • Nanolaminates coatings.
  • Nanostructure conformal coatings.
  • High-aspect ratio feature coatings.
