Role Overview
We are looking for a Process Engineer to develop and industrialize semiconductor fabrication processes, bridging Advanced R&D and Production.
This hands-on role focuses on dry etching (ICP-RIE), PECVD and metal evaporation. Working closely with R&D and cleanroom operators, you will improve device performance, process reproducibility, yield and throughput.
Key Responsibilities
1. Equipment Validation and Recipe Transfer
- 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.
2. Production Capacity and Yield
- Prepare processes for larger wafers, batches and production volumes.
- Improve process robustness, uniformity and yield.
- Establish process monitoring, KPIs and Statistical Process Control (SPC) where relevant.
- Investigate process drifts, yield losses and equipment issues; implement corrective and preventive actions.
3. Device Performance
- Optimize fabrication parameters, particularly dry etching, using structured experimentation and scientific literature.
- Correlate process data with structural, optical and electrical characterization to understand their impact on device performance.
4. R&D-to-Production Transfer
- Turn R&D building blocks into stable, documented manufacturing processes.
- Assess manufacturability, scalability and process risks.
- Contribute to Process Failure Mode and Effects Analysis (PFMEA) and define appropriate controls.
How You Will Grow :
First 3 months: Learn Quandela’s fabrication and characterization flow and contribute to ongoing technical challenges.
Within 6 months: Take ownership of a tool, validate new equipment and support the transition to larger wafers and batches.
Within 1 year: Improve device performance, strengthen statistical process monitoring and support increasing production volumes.
Requirements
Requirements
Must-Have
- PhD or equivalent research and development experience in semiconductor engineering, materials science, physics, micro/nanotechnology, electrical engineering or a related field.
- Hands-on cleanroom experience in semiconductor fabrication, including dry etching, ideally ICP-RIE.
- Experience with complementary processes such as PECVD, metal evaporation or lithography.
- Understanding of optics and optoelectronics sufficient to connect fabrication parameters with device performance.
- Ability to independently troubleshoot technical problems using experimental data, root-cause analysis and scientific literature.
- Strong communication and documentation skills, with fluent written and spoken English.
- Familiarity with Python for data analysis.
Appreciated Extra Skills
- In-depth knowledge of plasma etching physics and diagnostics, such as actinometry, ion-flux measurements or residual gas analysis.
- Experience with plasma-tool maintenance and process-drift correction.
- Experience with industrialization, R&D-to-production transfer, PFMEA, control plans, SPC or Design of Experiments (DoE).
- Experience with optoelectronic-device design and characterization.
- Knowledge of III-V semiconductors, particularly AlGaAs photonic structures, resonators or VCSEL technologies.
Profile
You combine R&D curiosity and analytical skills with manufacturing rigor. You enjoy hands-on cleanroom work, data analysis and collaborative problem-solving, and can turn exploratory processes into controlled production workflows.
Benefits
- Competitive salary, flexible based on your experience
- Profit-sharing & company savings plan
- 100% health coverage (Alan)
