Research Scientist, QPU Integration and TSV Technologies

Are you interested in superconducting quantum device fabrication and three-dimensional integration? We are offering an exciting opportunity to develop through-silicon via technologies that enable the scaling of future quantum processors. Would you like to work hands-on in a state-of-the-art cleanroom and turn advanced research into reproducible, pilot-ready processes? VTT might be just the place for you. VTT is one of the leading applied research organisations in Europe. What unites us are curiosity, a passion for learning, and a purpose: to solve the biggest challenges of our time and turn them into sustainable growth and well-being. Our cross-disciplinary community of over 2000 brilliant minds from 55+ different nationalities focuses on creating impact through science-based innovation. In recent years, we have created ground-breaking innovations such as the world's fastest and most accurate radiation detector, a cancer-sniffing sensor device for smartphones, and a headphone set entirely made of microbial materials. Get to know us further by exploring VTT's tech & infra . We are now looking for Research Scientist, QPU Integration and TSV Technologies to join our Quantum Scaling and Integration team. You will join our Quantum Scaling and Integration Team, contributing to the development of superconducting through-silicon via processes and QPU integration technologies on 200 mm wafers. In this role, you will develop, characterize, and optimize key fabrication modules in close collaboration with senior scientists, device integration experts, packaging teams, and European partners. You will help bridge advanced quantum research and scalable manufacturing. Our Quantum Scaling and Integration Team develops advanced technologies for scaling superconducting quantum processors, from TSVs and multilayer wiring to flip-chip integration and full QPU module concepts. We work closely with leading European industrial and academic partners to enable reproducible, wafer-scale fabrication and pilot-ready processes for future quantum computing systems. As Research Scientist, QPU Integration and TSV Technologies, you will: Develop, optimize, and qualify superconducting TSV processes on 200 mm wafers Perform thin film deposition, lithography, DRIE/RIE/ICP-RIE, and wet processing Contribute to process integration, scaling, and tool matching across fabrication platforms Plan and execute DOE campaigns and short-loop experiments for yield and performance optimization Improve process stability, reproducibility, and wafer-scale uniformity Carry out in-line and wafer-level characterization such as SEM, electrical probing, and resistance mapping Analyze relationships between process parameters and electrical and device performance Support process monitoring, SPC, 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 Who we are looking for: For this position, we are looking for a hands-on expert in micro- and nanofabrication who is motivated to develop scalable integration technologies for quantum processors.
