Senior Engineer II, Systems Engineering - Plasma
Originally posted 9 November 2026 by the employer.
About the role
The Systems Engineer II, Plasma is responsible for the development, characterization, integration, and deployment of plasma-based sensing, diagnostics, and process control technologies across ASM semiconductor manufacturing equipment. The role resides within the Sensor Technology Group, focusing on understanding plasma behavior, developing diagnostic methodologies, and leveraging process data to improve process performance and reliability.
What you'll do
- Support the development, characterization, and qualification of plasma-based processes, subsystems, and technology upgrades across ASM product platforms.
- Evaluate plasma behavior, plasma-surface interactions, and process performance under varying operating conditions to improve stability, uniformity, and repeatability.
- Develop and implement diagnostic methodologies utilizing tools such as Optical Emission Spectroscopy (OES), RF diagnostics, VI probes, Langmuir probes, and Residual Gas Analysis (RGA).
- Correlate diagnostic measurements with process performance and characterize hardware performance to identify opportunities for process optimization.
- Design experiments and collect, analyze, and interpret complex process and equipment datasets in collaboration with Process, Mechanical, Electrical, Software, Firmware, and Manufacturing Engineering teams.
What you'll need
- Experience in plasma systems engineering, plasma science, or process diagnostics within semiconductor manufacturing equipment.
- Direct hands-on experience using diagnostic tools such as Optical Emission Spectroscopy (OES), RF diagnostics, VI probes, Langmuir probes, or Residual Gas Analysis (RGA).
- Demonstrated capability in design of experiments (DOE), analyzing complex process datasets, and evaluating plasma-surface interactions.
- Background participating in requirements definition, test planning, and technology validation activities across multidisciplinary engineering teams.
