As Moore's Law decelerates, the performance enhancement in electronic devices and chips becomes increasingly challenging. In response to the urgent demand for high performance and low power consumption, Professor Kuan-Chang Chang introduces environmentally friendly low-temperature supercritical fluids into the field of electronics. Leveraging a multidisciplinary research background, he has conducted an in-depth exploration of the interplay between supercritical fluids and electronic devices/materials. This report outlines the bottlenecks faced by electronic devices and materials, the challenges that need addressing, and introduces the characteristics and applications of supercritical fluids. Emphasis is placed on various supercritical fluid methodologies developed by Chang’s research group, encompassing oxidation, carbide formation, dehydrogenation, purification, and on the research progress of these supercritical approaches made in diverse electronic devices and materials. Furthermore, the report delves into the application of supercritical fluids in fields such as neuromorphic devices, bio-materials, and related devices, and provides prospects for the future development of supercritical fluid applications.
