Jobbeschreibung

The opportunity

The energy landscape is rapidly evolving, requiring increasingly complex and reliable power distribution systems. The growing integration of renewable energy sources and converter interfaces introduces new challenges for transmission and distribution operators. Silicon carbide (SiC) power semiconductors have matured significantly and offer superior electrical performance, making them highly attractive for power electronics applications. However, challenges related to the gate stack reliability of SiC MOSFETs must still be addressed to enable their widespread adoption. The Semiconductors Packaging and Reliability Engineering research team seeks an intern to support the development of an innovative test setup for reliability investigations. The setup targets threshold voltage stability of SiC MOSFETs under extensive cycling and accelerated aging conditions. The successful candidate will develop and monitor a real-time system for tracking device aging. Experiments are conducted on a double pulse tester with a half-bridge evaluation board rated at 3.3 kV and 150 A. The internship duration is six months.

How you'll make an impact

• Conduct measurement campaigns and data analysis based on the latest models available in literature

• Propose innovative solutions for gathering more insights from the experimental tests: creating sensors array prototypes and automated data collection software

• Optimize a half-bridge converter for long-term dynamic testing of SiC MOSFETs

• Upgrade test electronics and data acquisition software needed to run high-precision measurements for extended test time

• Document and communicate the solutions developed, to disseminate the gained knowledge within the research team, academic collaborators and the business unit of pertinence

Your background

• Currently pursuing a Masters degree in electronics engineering, materials engineering, physics or a related discipline (official enrolment is essential)

• Familiar with electrical measurements setup and with the design and construction of electronics systems. Previous experience with semiconductor physics and/or power devices is a strong plus

• Experience with LabView programming, and knowledge of programming languages (e.g. Python, C, Matlab)

• Fluency in written and spoken English

• Good communication and technical writing skills

• Creative and able to work autonomously
