Quantum Nanofabrication Scientist — Multi-Layer Wiring

VTT; Espoo; On-site; EUR 70,000 - 100,000; Full time

Job summary

VTT in Espoo is seeking a Research Scientist, Multi-Layered Wiring, to advance superconducting nanofabrication for quantum processors. You will work hands-on in cleanroom and characterization labs, developing and qualifying wiring stacks on 200 mm wafers, and collaborating with senior scientists and EU partners.

The role emphasizes reproducible pilot-scale processes, design-of-experiments, data-driven optimization, and close interaction with cross-functional teams to bring quantum hardware from

Qualifications

• MSc or PhD in applied physics, electrical engineering, materials science, micro/nanotechnology, or similar.
• At least 3 years of cleanroom experience (incl. thesis or postdoc work).
• Experience in lithography, etching, thin film deposition, and microfabrication processes.
• Understanding of process integration, characterization, and fabrication workflows.
• Experience with DOE, data analysis, or process optimization.
• Basic programming skills (e.g., Python).
• Knowledge of CMP, wafer bonding, or advanced packaging; familiarity with superconducting materials.

Responsibilities

• Develop, optimize, and qualify nanofabrication processes for superconducting multi-layered wiring stacks
• Perform thin film deposition, lithography, dry etching (RIE/ICP), and wet processing
• Contribute to process integration, scaling, and transfer across fabrication platforms
• Plan and execute DOE and analyze data for process optimization
• Improve process stability, reproducibility, and wafer-scale uniformity
• Carry out in-line and wafer-level characterization (e.g. SEM, electrical probing)
• Analyze process-performance relationships and support continuous improvement
• Support process control, yield tracking, and KPI definition
• Collaborate with internal teams and external partners in EU projects and research initiatives
• Contribute to documentation, technology transfer, and pilot-scale process development
