From FinFET to CFET: Semiconductor Roadmap, Materials & Device Junctions | 2026 L2

Value of the Information & Strength of the Argument

The lecture provides a comprehensive overview of the semiconductor roadmap, connecting device scaling goals to power consumption challenges. It effectively argues that reducing subthreshold swing and off-current are key to lowering operating voltage and power. The discussion of more-than-Moore technologies, such as GaN and SiC for power conversion, illustrates the broader impact of semiconductor innovation. The argumentation is logical and well-structured, though some claims (e.g., efficiency improvements) are presented without detailed evidence.

Scientific Rigor, Source Quality, Title Accuracy

The lecture is scientifically rigorous, based on established semiconductor physics and industry trends. It references TSMC roadmaps and NVIDIA data, but these are not formally cited. The title accurately reflects the content, which covers the roadmap from FinFET to CFET and discusses materials and junctions. The lecture is suitable for an academic audience, and the content is consistent with current knowledge in the field.
