Semiconductors Advance to Angstrom Scale—NCKU's Breakthrough Gains Global Attention.-國立成功大學永續發展SDGs

Currently, semiconductor manufacturing primarily operates at the nanoscale, but the industry is pushing toward the angstrom scale (one-tenth of a nanometer). NCKU’s Assistant Professor Bang-Yu Hsu’s team has utilized self-assembled equipment to achieve angstrom-scale precision, advancing semiconductor processes. This breakthrough, published in the prestigious journal Macromolecules, has gained significant international attention.(Forming Long-Range Order of Semiconducting Polymers through Liquid-Phase Directional Molecular Assemblies)


Bang-Yu Hsu highlights that, beyond the recognition, the team is proud of their advanced technology developed using cost-effective, self-assembled equipment. Despite Taiwan’s leading semiconductor industry investing billions, NCKU proves that creativity and expertise can achieve remarkable results with limited resources.


Hsu notes that while current semiconductor processes achieve sub-3-nanometer precision, the push toward angstrom precision is a necessary industry evolution. The team’s work addresses significant technical challenges and demonstrates high precision and control at the angstrom scale, achieving orderly molecular arrangements over large areas, which was previously considered unattainable.


The team, including graduate students Yong-Ping Yang, Cheng-Tai He, Yu-Han Huang, and Tzu-Cheng Hsu, assembled advanced equipment themselves, such as systems combining low-temperature, micro-Raman scattering, and visible light absorption, at a fraction of commercial costs. This hands-on approach has provided valuable practical experience and demonstrated that innovation can succeed even with limited funding.
