Job summary

Quandela, based in Palaiseau, Île-de-France, France, seeks a Process Engineer to develop and industrialize semiconductor fabrication processes. The role focuses on dry etching (ICP-RIE), PECVD and metal evaporation, collaborating with R&D and cleanroom operators to boost yield and throughput.

You will lead acceptance testing, recipe transfer, tool maintenance, and process monitoring to ensure robust, scalable manufacturing.

Qualifications

• In-depth knowledge of plasma etching and diagnostics (actinometry, ion flux, RGA).
• Experience with plasma-tool maintenance and process-drift correction.
• Experience with industrialization and R&D-to-production transfer (PFMEA, control plans, SPC, DoE).
• Experience with optoelectronic-device design and characterization.
• Knowledge of III–V semiconductors, particularly AlGaAs photonic structures, resonators or VCSELs.

Responsibilities

• Define and run acceptance tests with the maintenance engineer.
• Transfer and optimize recipes on new equipment.
• Establish maintenance, cleaning and conditioning procedures.
• Validate wafer-to-wafer and day-to-day reproducibility through extended runs.
• Prepare processes for larger wafers, batches and production volumes.
• Improve process robustness, uniformity and yield.
• Establish process monitoring and SPC as relevant.
• Investigate drifts, yield losses and equipment issues; implement corrective actions.
• Optimize fabrication parameters, especially dry etching, using structured experiments.
• Correlate process data with structural, optical and electrical characterization to understand device impact.
• Turn R&D building blocks into stable manufacturing processes; assess manufacturability and risks.
• Contribute to PFMEA and define appropriate controls.
