Doctoral Researcher – Heterogeneous Integration for Power Electronics

Electronics Integration and Reliability (EILB) (Electronics Integration and Reliability | Aalto University) is a research group at Aalto University School of Electrical Engineering. We advance next‑generation electronics through innovative materials, device design, and bonding technologies. By leveraging high‑quality AlN and high‑Al‑content AlGaN, distributed polarization doping, and advanced packaging and interconnection concepts, we develop solutions for cutting‑edge power electronics based on wide‑bandgap (WBG) and ultra‑wide‑bandgap (UWBG) semiconductors, as well as for RF applications and smart sensors. Our mission is to enable miniaturized, sustainable, and energy-efficient systems with superior power handling, higher breakdown voltages, and enhanced high temperature performance.

We are looking for a doctoral researcher to advance miniaturised, high‑density heterogeneous integration of WBG and UWBG power electronics through novel high‑temperature interconnects—including solid–liquid interdiffusion (SLID), hybrid and diffusion bonding, and sintering technologies—in collaboration with our international research partners. The research will investigate how interconnect interfacial compatibility, metallurgy and microstructures, and local interface states and defects influence electrical and thermal performance, and long‑term reliability of power electronic modules. These innovative solutions necessitate profound requirement specifications and co-design of thermal, thermomechanical, and microstructural aspects, based on a deep understanding of the electrical requirements of WBG/UWBG semiconductors. The goal is to design, manufacture, and characterise reliable, highly integrated, ultra‑high‑power‑density power modules [~50 kW/L (or kg)] or “power chiplets”. These power modules incorporate innovative control and sensing functions by utilising novel interconnection technologies, which are developed by utilizing advanced materials characterisation methods, electrical and thermal measurements, and multiphysics modelling.

Requirements

• M.Sc. or equivalent degree in a suitable area (e.g. electrical engineering, physics or materials science)
• good knowledge and understanding of WBG and UWBG power semiconductor technologies
• experience in multiphysics simulation tools such as COMSOL, ANSYS and circuit design tools like SPICE or PLEX
• experience of working in a cleanroom  
• experience or genuine interest in advanced microfabrication, novel interconnection and material characterization methods
• experience or genuine interest in electronics reliability assessment and failure analysis tools
• strong analytical and writing skills

If you are chosen for this position, you will then apply for the study right in doctoral studies at Aalto University School of Electrical Engineering. Thus, please see the student information and admission criteria at https://www.aalto.fi/en/study-options/aalto-doctoral-programme-in-electrical-engineering.

We offer

• The position is fixed term and follows the school’s standard 2+2 model for doctoral researchers. It will be made initially for two years, with a six-month probationary period, and extended by two further years after a successful mid-term review, giving a total duration of four years
• opportunity to conduct independent research in a cutting-edge OtaNano infrastructure of Micronova (https://www.aalto.fi/en/otanano/micronova) and Nanomicroscopy Center (https://www.aalto.fi/en/otanano/nanomicroscopy-center)
• possibility of building international industrial and academic networks within large national and pan-European public-private-partnership projects, in which the EILB team is participating
• multidisciplinary course curriculum of Aalto University
• starting salary of 3143 €/month
• occupational health and social security benefits

The position is available immediately
