AtOMS Atomic Spectroscopy for Advanced Thin Film Process Control

Atomic Spectroscopy for Advanced Thin Film Process Control

Advances in thin film coating and architectures are quickly outpacing the capacities of conventional monitoring systems. AtOMS (Atomic Absorption Optical Emission Spectroscopy System), powered by Accustrata, enables you to move beyond traditional method of monitoring and process control by measuring where it matters. Establish a competitive edge in manufacturing yield, product performance, and process stability in thin film etching and deposition.

“By working together with ADS and National Instruments, we believe we can solve the toughest RF spectrum record, playback, real-time analysis and real-time emulation problems that face our mutual customers in the aerospace, defense, aviation and communications industries.”

Operational Environments that will benefit from AtOMS

Key Features

  • Developed by Accustrata under US Department Energy Program for in-situ process control in the manufacturing of extreme UV optical coating for 13.5 nm lithography.
  • Simultaneously monitors deposition rate, film, quality and composition.
  • Monitors any material: metals, alloy, opaque materials, semiconductors and dielectrics.
  • Fiber optics-based solution allows installation on any chamber geometry without chamber redesign.
  • Multi-beam measurement close to substrate allows in-situ control of uniformity.
  • Optical components uniquely designed to prevent sensor contamination.
  • Works with any substrate shape and rotation.
  • Reduced maintenance and cost compared to quartz crystal and optical monitors.

How it Works

  • The system collects the plasma emission in the range 190-800 nm in real-time and analyzes the spectrum to detect specific emission peaks of some elements and radicals, that are specific for the deposition/etching process.
  • The system launches a probe beam of light at a wavelength, specific to the element it needs to monitor. It uses a specific hollow cathode light (HCL) sources, which emit the desired wavelength.
