One Tool, Many Solutions

The ASTON Platform supports the broad metrology needs, including the precise in-situ process management required in today’s industry.

Aston is up to 20x more sensitive in detecting end point in high-speed sampling applications. This is especially important when measuring low concentration byproduct gases, where signal to noise ratio is critical to informing process decisions.

The ASTON Platform solves the key in-situ metrology issues

  • Corrosive gases damage sensor
    ASTON is resistant to HCl and HF as process byproducts, NF3 for chamber cleans
  • Condensate particles coat sensor
    ASTON is resistant to TEOS & Silane byproducts used for Silicon Nitride & Oxide Deposition
  • Speed and sensitivity
    ASTON delivers best-in-class, high-speed measurements combined with PPB level sensitivity for process control

Engineered from the ground up for in-situ semiconductor metrology applications.
