A Seoul Nationwide College School of Engineering analysis workforce led by Professor Lee Jong-ho of the Division of Electrical and Pc Engineering (former Minister of Science and ICT) has developed next-generation synthetic intelligence (AI) semiconductor know-how that may scale back energy consumption and dramatically improve safety capabilities. This represents analysis achievements associated to ferroelectric supplies, a brand new materials attracting consideration within the physics group, and neuromorphic semiconductors, the ‘next-generation semiconductors that mimic the mind’.
The analysis outcomes are drawing consideration as they emerge amid ongoing safety incidents together with Web of Issues (IoT) hacking of Chinese language-made robotic vacuum cleaners and unauthorized small-payment accidents brought on by unlawful femtocells from cellular carriers.
Seoul Nationwide College School of Engineering introduced on the twenty fourth that three papers by Professor Lee’s analysis workforce have all been accepted at ‘IEEE (Institute of Electrical and Electronics Engineers) 2025’, the world’s most prestigious semiconductor know-how convention. Professor Lee is a world-renowned semiconductor scholar who first developed the three-dimensional (3D) bulk FinFET, a semiconductor micro-process construction, along with KAIST researchers.
A Seoul Nationwide College official mentioned, “Just lately, demand for low-power, high-reliability semiconductors has surged as a result of unfold of superior applied sciences equivalent to AI, IoT, and autonomous autos,” including, “Nonetheless, current semiconductors have unresolved points together with excessive energy consumption, low safety, and insufficient sensing capabilities.”
Professor Lee’s workforce introduced three analysis achievements: ultra-low-power reminiscence gadgets, hardware-based safety semiconductors, and clever gasoline sensor techniques.
Within the first analysis, they proved the innovation potential of ferroelectric reminiscence, one kind of non-volatile reminiscence. They revealed that by introducing a ‘pseudo-lattice’ construction to skinny movies surrounding hafnium-zirconium composite oxide, a ferroelectric materials, they concurrently achieved world-class polarization traits and low working voltage. By way of this, they opened prospects for implementing ultra-low-power reminiscence and neuromorphic {hardware}, the next-generation AI computing system.
Within the second analysis, they developed Bodily Unclonable Operate (PUF) know-how using ‘magnetic tunnel junction’, one other next-generation non-volatile reminiscence operation methodology. The analysis workforce proved that they may stably generate and conceal unclonable {hardware} safety keys utilizing the breakdown likelihood traits of gadgets. This may be utilized as a next-generation semiconductor resolution with excessive safety capabilities.
Within the third analysis, they introduced a blended gasoline discrimination system that integrates gasoline sensors and circuits on a single chip. They initially designed a ‘self-canceling circuit construction’ and utilized it to sensors, implementing an ultra-miniature, ultra-low-power system.
Seoul Nationwide College defined that “all three analysis tasks are suitable with current CMOS (Complementary Steel-Oxide-Semiconductor) processes, making commercialization possible.” The magnetic tunnel junction Bodily Unclonable Operate know-how might be utilized for authentication and encryption in smartphones, vehicles, IoT gadgets, and extra. The self-canceling circuit construction gasoline sensor system is anticipated to be broadly relevant in fields equivalent to meals, setting, drugs, and industrial security.
Yoo Sang-woo, the primary creator of the primary analysis, pursued his doctoral course at Seoul Nationwide College whereas working at SK Hynix. Lee Kyung-min, the primary creator of the second analysis, entered Seoul Nationwide College’s doctoral program whereas working at Samsung Electronics.
Professor Lee said, “On account of a convergent method encompassing semiconductor gadgets, supplies, circuits, and techniques, we’ve proven that Korea can preserve competitiveness in varied fields together with AI, safety, and sensors,” including, “We are going to proceed follow-up analysis to result in the commercialization of next-generation semiconductor know-how.”
