In a remarkable achievement, the Department of Electrical Engineering at National Taiwan University (NTU) boasts not one, but three professors serving as Editors-in-Chief for international journals under the prestigious Institute of Electrical and Electronics Engineers (IEEE). This exceptional distinction positions Taiwan's academic community squarely within the international academic mainstream. The Institute of Electrical and Electronics Engineers (IEEE), established in 1963, stands as a globally renowned association for electronic technology and electrical engineers. It ranks among the world's largest professional technical organizations, with a membership comprising approximately 430,000 professionals hailing from over 160 countries. IEEE operates in over 150 countries, features 39 specialized societies, and houses seven technical committees. Each year, IEEE publishes an impressive 258 technical journals and magazines and hosts more than 800 professional technical conferences worldwide. Moreover, IEEE holds a pivotal role in the development of international standards, with nearly 1,600 standards currently in effect.

The recent emergence of Gate-All-Around (GAA) technology has attracted significant attention due to its relevance in addressing the challenge of shrinking transistor sizes for the 3-nanometer semiconductor technology node. GAA technology enhances the gate's control over electric current by completely enveloping the electrical channel. It introduces a nanowire/nanosheet field-effect transistor architecture to boost performance. The transistor design has evolved from planar to now three-dimensional, transitioning from the fin-shaped structure to a multi-wire/multi-sheet configuration, aiming to maintain performance and enhance current flow while reducing size.

Research and development of miniaturized devices has long been a goal pursued by many scientists. Since Intel co-founder Gordon Moore proposed Moore’s Law in 1965, predicting that the number of transistors on a chip would double every 24 months
