Internship - Thermal Characterization of Power Devices (Rth Measurements)

OUR STORYAt STMicroelectronics, we believe in the power of technology to drive innovation and make a positive impact on people, businesses, and society. As a global semiconductor company, our advanced technologies and chips form the hidden foundation of the world we live in today.When you join ST, you will be part of a global business with more than 115 nationalities, present in 40 countries, and comprising over 50,000 diverse and dedicated creators and makers of technology around the world.Developing technologies takes more than talent: it takes amazing people who understand collaboration and respect. People with passion and the desire to disrupt the status quo, drive innovation, and unlock their own potential.Embark on a journey with us, where you can innovate for a future that we want to make smarter and greener, in a responsible and sustainable way. Our technology starts with you.You will contribute to test improvement activities focused on the thermal characterization of power devices . The goal of the internship is to develop and validate a robust measurement methodology for junction‑to‑case thermal resistance (Rth) on power packages, minimizing parasitic effects and ensuring both accuracy and repeatability of results.Main ResponsibilitiesPerform electrical and thermal measurements on power semiconductor packages (e.g. MOSFETs, IGBTs).Analyze and understand the influence of test conditions (mounting, boundary conditions, instrumentation, measurement sequences, etc.) on the measured Rth.Identify and reduce undesired effects and measurement artifacts (e.g. self‑heating dynamics, contact resistance, environmental influences).Propose, implement and validate an optimized measurement procedure for Rth, focused on:repeatability (short‑term and long‑term)measurement uncertainty and accuracyrobustness to operator and setup variationsProcess experimental data using basic statistics (repeatability, standard deviation, confidence intervals, comparison of methods).Document experimental setups, test conditions, procedures and results in clear technical reports and presentations .Required SkillsSolid background in basic electronics and circuit analysis (DC, AC, power circuits).Familiarity with electrical measurements (use of oscilloscopes, power supplies, multimeters, etc.).Basic understanding of heat transfer in electronic devices (thermal resistance, transient thermal behavior) is a strong plus.Ability to perform data analysis and basic statistical treatment (e.g. in Excel, MATLAB, Python, or similar).Good problem‑solving attitude and attention to experimental details .Ability to work in a laboratory environment, following safety and quality procedures .Good written and spoken English .ST is proud to be one of the 17 companies certified as a 2025 Global Top Employer and the first and only semiconductor company to achieve this distinction. ST was recognized in this ranking thanks to its continuous improvement approach and stands out particularly in the areas of ethics & integrity, purpose & values, organization & change, business strategy, and performance.At ST, we endeavor to foster a diverse and inclusive workplace, and we do not tolerate discrimination. We aim to recruit and retain a diverse workforce that reflects the societies around us. We strive for equity in career development, career opportunities, and equal remuneration. We encourage candidates who may not meet every single requirement to apply, as we appreciate diverse perspectives and provide opportunities for growth and learning. Diversity, equity, and inclusion (DEI) is woven into our company culture.To discover more, visit st.com/careers. #J-18808-Ljbffr
