Exploring the applications of plasma physics in the semiconductor industry through challenge-based learning

Abstract

This study investigates the integration of Challenge-Based Learning (CBL) into a master-level plasma physics course, with the aim of bridging the gap between academic research and industrial applications in the semiconductor sector. The course design centred on reverse-engineering fabrication processes for advanced nanoelectronics, challenging students to apply plasma processing concepts to authentic, industry-relevant problems. Using a mixed-methods design (surveys and interviews), we evaluated the impact of CBL on student engagement, skill development, and knowledge integration. Results show that students valued the open-ended nature of the challenge, reporting increased motivation, deeper understanding of theoretical concepts, and improved abilities in problem-solving, literature navigation, and critical evaluation of diverse information sources. While many students initially found the project overwhelming, structured scaffolding through weekly feedback, peer review and mentoring helped sustain motivation and build confidence. The findings demonstrate that CBL can be effectively adapted to conceptually dense courses, even in the absence of direct industry collaboration. We demonstrate that combining open-ended challenges with structured theoretical instruction provides a balanced approach, preparing students with both disciplinary expertise and transferable skills essential for today’s rapidly evolving technological landscape.
