Join Us at the Forefront of Quantum Computing Innovation 🚀 Role Overview We are looking for a Process Engineer to support the development, stabilization and industrialization of our semiconductor fabrication processes. At our current stage of maturity, this position combines advanced process development, hands-on R&D and manufacturing engineering. The Process Engineer will play a key role in bridging the gap between Advanced R&D and Production, transforming newly developed process building blocks into robust, repeatable and scalable manufacturing processes. The role will have a strong focus on dry etching processes, particularly ICP and RIE, as well as PECVD and metal evaporation. The successful candidate will work closely with R&D teams, fabrication engineers, equipment owners and cleanroom operators to improve process capability, reproducibility, yield and production throughput. This is a highly hands-on position requiring a strong understanding of semiconductor fabrication, rigorous experimental methodology and the ability to investigate complex interactions between process parameters and device performance. Key Responsibilities Process Development & Industrialization • Develop, optimize and stabilize semiconductor fabrication processes, with a primary focus on ICP / RIE dry etching, PECVD deposition and metal evaporation. • Validate and qualify new fabrication equipment and associated processes. • Define process windows, recipes, operating conditions and acceptance criteria. • Use structured experimentation, including Design of Experiments (DoE) where appropriate, to understand process sensitivities and optimize performance. • Improve process repeatability, reproducibility, robustness and within-wafer / wafer-to-wafer homogeneity. • Prepare processes and equipment for increasing wafer sizes, batch sizes and production volumes. R&D to Production Transfer • Act as a key technical interface between Advanced R&D and Production. • Convert R&D process building blocks into stable, documented and manufacturable processes. • Assess manufacturability, scalability and process risks before transfer to production. • Define qualification plans and acceptance criteria before releasing new or modified processes to production. • Lead or contribute to Process Failure Mode and Effects Analysis (PFMEA) for critical fabrication steps, identifying potential failure modes, their effects on device performance and appropriate prevention and control measures. • Translate PFMEA outcomes into process controls, monitoring plans, acceptance criteria, Control Plans and documentation. • Support technology transfer through clear documentation, operator training and technical communication. Process Control & Yield Improvement • Monitor and improve production process performance, yield and throughput. • Establish regular process checks, controls and monitoring methodologies, including Statistical Process Control (SPC) where relevant. • Detect process drifts, investigate deviations and define corrective and preventive actions. • Lead root-cause analysis and troubleshooting activities for yield losses, process excursions and equipment-related issues. • Define and maintain relevant process KPIs and contribute to continuous-improvement initiatives. • Promote best practices that increase process stability, repeatability and equ
