Senior Process Engineer Plasma

About This Position
At the forefront of Europe's photonics innovation, TNO is building a state-of-the-art pilot line for Indium Phosphide (InP) photonic chips at the High Tech Campus in Eindhoven. As part of the EU-funded PIXEurope program, this pilot line will enable the transition from groundbreaking research to large-scale industrial manufacturing, making advanced photonic technologies faster, more reliable, and widely accessible. To help realize this ambitious step, we are looking for a Senior Process Engineer Plasma. In this role, you will develop, optimize, and manage plasma processes that are critical for wafer-scale photonic chip production. With your expertise in deposition and etching of dielectrics and dry etching of III/V semiconductor materials, you will ensure that innovative research is transformed into stable, scalable, and high-yield manufacturing processes.

What will be your role?
As Senior Process Engineer Plasma, you are responsible for process development and optimization in a high-tech cleanroom environment. You will focus on deposition and etching of SiO2 and SiN layers, as well as dry etching processes for III/V semiconductors such as InP, GaAs, and GaN, enabling robust 6-inch wafer manufacturing. By collaborating with R&D, equipment engineers, and QA teams, you ensure stable production, improve yield, and introduce new technologies into the pilot line.

Key responsibilities include

• Developing, qualifying, and improving plasma processes (e.g. PECVD, ICP, RIE) for 6-inch InP wafers.
• Analyzing process data, performing root cause analyses, and applying statistical methods (SPC, FMEA, DoE).
• Supporting operators and technicians with process-related issues, ensuring smooth continuation of wafer manufacturing.
• Troubleshooting disruptions and ensuring process stability and quality.
• Leading improvement projects and the introduction of new plasma tools and processes.
• Collaborating in cross-functional teams (R&D, Equipment, QA) and reporting progress to management.
• Creating and maintaining process documentation, work instructions, and best practices.
• Conducting audits and quality checks to ensure compliance and reliability.
• Mentoring junior engineers, acting as a sparring partner for cluster leads, and representing process engineering in the absence of the team leader.

What We Expect From You
You are a highly skilled process engineer with deep knowledge of plasma etching and industrial wafer manufacturing. You combine analytical strength with hands-on problem solving and leadership skills. You thrive in a cleanroom environment and are motivated to shape Europe's future in integrated photonics.

You Also Bring The Following Qualifications

• A PhD, MSc, or BSc degree in physics, chemistry, materials science, electrical engineering, or a related field.
• 8+ years of experience in semiconductor process engineering, preferably in industrial wafer fabs.
• Strong expertise in dry etching of III/V semiconductor materials such as InP, GaAs, or GaN.
• Proven experience in process development, optimization, troubleshooting, and yield improvement.
• Familiarity with statistical tools (SPC, FMEA, DoE) and process characterization methods.
• Leadership experience as a cluster lead or acting cluster lead.
• Coaching and mentoring skills, with the ability to support junior colleagues and guide larger projects.
• A strategic and analytical mindset, with excellent communication and stakeholder management abilities.

What You'll Get In Return
