The opportunity

As a global leader in power semiconductors, we offer one of the most diverse product portfolios including thyristors, diodes, GTOs, IGCTs, IGBTs and MOSFETs recognized by industry, power transmission & distribution, mobility, renewable energy for their ultimate in quality and reliability. As a Senior Engineer in Photolithography, you will lead the development, optimization, and implementation of lithography processes for power semiconductor manufacturing. You will work cross-functionally to ensure high yield, process stability, and continuous improvement across the production line.

How you’ll make an impact

• Lead the development and optimization of photolithography processes to ensure high yield, stability, and cost-efficiency

• Drive continuous improvement initiatives across the production line, focusing on throughput, quality, and innovation

• Collaborate with cross-functional teams (wet etch, diffusion, metals, dry etch, implant, integration) to ensure seamless process integration

• Evaluate and implement new technologies in partnership with equipment and material suppliers

• Analyze process data using SPC and other statistical tools to identify trends and troubleshoot issues

• Plan and lead equipment installation, qualification, and ramp-up activities

• Support metrology tools and methodologies, including CD and overlay measurements

• Document and communicate project plans, results, and recommendations clearly and effectively

Your background

• Master’s degree in Electrical Engineering, Physics, Materials Science, or a related field

• Ideally 5 years of hands-on experience in photolithography process engineering within the semiconductor industry

• Deep understanding of lithography principles, resist chemistry, and process integration

• Experience with lithography tools (e.g., steppers, coat/develop tracks)

• Proficiency in data analysis tools (Python, Excel) and statistical methods (SPC, DOE)

• Strong communication, problem-solving, and project management skills

• Fluent in English; German is a strong plus

• Willingness to participate in on-call duties during weekends and public holidays as required by production
