The AJA UHV Orion dielectric sputter system is capable of reaching UHV pressures as low as 1E-10 Torr. It is equipped with a load lock that allows for automatic sample transfer. There are eight magnetron guns, seven 2" guns, and one 3" gun. A total of two RF and three DC power supplies can be used on any of the eight guns, some with an internal switch box allowing for one power source to be sequentially routed to different guns, enabling automatic processes without manual cable swapping. One of the DC guns is a pulsed DC supply. Uniformity across a 6" wafer is <5% variation for the 2" guns. Pre-mixed targets of specific alloys and compounds may be sputtered. In addition, having multiple power supplies allows for co-sputtering of up to five materials simultaneously. Reactive sputtering may be performed by introducing oxygen and/or nitrogen into the chamber during process, allowing oxides and nitrides to be formed from pure metal targets. The pulsed DC supply is ideally suited for such reactive processes where a dielectric material is synthesized. Co-sputtering multiple elements in a reactive process can produce complex ceramics. An RF power supply is also present specifically for generating a localized plasma at the substrate. This can be used as a surface cleaner, etcher, for techniques such as ion-assisted deposition, and to assist in the reactive formation of metal-nitrides. This tool is also capable of substrate heating up to 800 °C, which can be used to facilitate reactions, alloying, to control film stress, and to control crystal growth mechanisms.

Reasons to Utilize Sputtering
  • Ability to synthesize compounds and control compositions
  • Wide variety of high quality oxides & nitrides may be synthesized
  • Generally produces more uniform, better adhering films when compared to evaporation
  • More conformal sidewall coverage for coating patterned substrates
    • More conformal than evaporation, less conformal than CVD & ALD
  • Metal and dielectric deposition
  • Surface cleaning & in-situ plasma etch
  • Ion-Assisted Deposition
