On Monday, April 14, Seoul National University signed a Memorandum of Understanding (MoU) with Hyundai Engineering & Construction for collaboration on the development and commercialization of superconductor-based fusion reactor technology. The signing ceremony was held at Seoul National University’s Gwanak campus, with key figures in attendance, including SNU President Honglim Yoo and Hyundai E&C CEO Hanwoo Lee. Fusion power technology—often referred to as the “energy of dreams”—is gaining attention as a game-changer in the future energy sector. It has abundant fuel, poses low risk of explosion, and produces minimal emissions and radioactive waste, making it a safe and clean energy source capable of addressing both the explosive power demand driven by the Fourth Industrial Revolution and the goal of carbon neutrality. One of the core technologies of nuclear fusion is maintaining ultra-high-temperature plasma in a stable state for extended periods. To achieve this, a strong magnetic field generated by superconducting magnets is used to effectively confine the plasma. With recent advances in high-temperature superconducting magnet technology, the magnetic field strength inside fusion devices has more than doubled compared to previous technologies. As a result, the massive superconducting magnets used in fusion reactors—once spanning several tens of meters—are now being scaled down to just a few meters, making compact fusion reactors a reality. This breakthrough is fueling rapid growth in the field, with global private sector investments surpassing 10 trillion KRW, aiming for commercialization by the 2030s. Seoul National University is a global leader in high-temperature superconducting magnet and application research, centered around the Applied Superconductor Research Center (Director: Prof. Seungyong Han, Department of Electrical and Computer Engineering). Additionally, the university leads fusion research through the Fusion Reactor Engineering Research Center (Director: Prof. Yongseok Hwang, Department of Nuclear Engineering), which operates the VEST (Versatile Experiment Spherical Torus) device for education and research purposes. Supported by the Ministry of Science and ICT (MSIT), the High-Temperature Superconducting Magnet Technology Development Project (2022–2026, Project Director: Visiting Professor Sangjin Lee, Department of Electrical and Computer Engineering) is led by the Applied Superconductor Research Center. This large-scale national initiative involves over 200 researchers across 27 institutions in Korea and focuses on developing a wide range of core source technologies related to high-temperature superconducting magnets. The outcomes of this project are having a broad impact, including technological collaboration with Hyundai E&C in the field of fusion energy, and extending to both domestic and international superconducting applications. In July 2024, the Ministry of Science and ICT (MSIT) announced a 1.2 trillion KRW initiative titled the “Accelerated Realization Strategy for Fusion Energy”, highlighting the importance of technological innovations—such as high-temperature superconducting magnet technology—and public-private collaboration in advancing the commercialization of fusion energy. As a follow-up to this strategy, the government established the Fusion Innovation Alliance (Director: Boseon Kang, Director of KFE Center), an independent, industry-led organization aimed at laying the groundwork for private-sector growth and promoting the industrialization of fusion. Through this alliance, MSIT is also emphasizing the importance of university-industry collaboration in fusion-related research. Through this agreement, Seoul National University and Hyundai Engineering & Construction plan to closely collaborate on superconducting fusion reactor technologies, both domestically and internationally. Their cooperation will include: △ Joint research and technology development △ Business development and participation △ Human resource support and operation of mutual consultative bodies. Seoul National University will accelerate its research into core technologies in the fields of fusion and superconductivity, while Hyundai E&C, drawing on its extensive experience with various large-scale nuclear power plants including SMRs,aims to take a leading role in the construction and commercialization of fusion power plants. Together, the two institutions intend to generate strong synergy based on their unique strengths and drive innovation in future energy. Furthermore, Seoul National University recently launched the SNU Energy Initiative (SNU Energy Initiative, Chair: Professor Sungjae Kim, Department of Electrical and Computer Engineering) to comprehensively address issues across the full energy lifecycle. This new agreement with Hyundai E&C is expected to serve as a foundation for exploring new alternative solutions for future energy production together with SNU Energy Initiative. President Honglim Yoo of Seoul National University stated, “This agreement marks an important milestone in the history of superconductivity and fusion research in Korea. Through the collaboration between our two institutions, I hope our country will secure world-leading technological capabilities and contribute to strengthening national competitiveness.” Hanwoo Lee, CEO of Hyundai Engineering & Construction, remarked, “This partnership between leading academic and industrial institutions in Korea is expected to drive a new momentum for the transition to future energy. Today’s agreement is a meaningful step toward moving fusion power development from the laboratory to the construction of commercial reactors, ultimately creating real-world value.” This MoU between Seoul National University and Hyundai Engineering & Construction represents the first instance of a major Korean conglomerate formally entering the fields of fusion energy and high-temperature superconductivity, marking a significant milestone in the history of domestic research in these areas. Moreover, the agreement is especially meaningful as it lays the groundwork for rapidly securing a foothold in the global market, leveraging Korea’s world-class superconducting fusion technology at a time when international competition in this domain is intensifying.

Professor Jaejoon Kim, Department of Electrical and Computer Engineering, Seoul National University [Provided by the Ministry of Science and ICT. Redistribution and database storage prohibited.] (Seoul = Yonhap News) Reporter Cho Seung-han – The Ministry of Science and ICT and the National Research Foundation of Korea announced that Professor Jaejoon Kim of the Department of Electrical and Computer Engineering at Seoul National University has been selected as the May recipient of the Scientist of the Month Award. Professor Kim was recognized for his contributions in developing lightweight AI models and designing semiconductor accelerators that efficiently compute these models, thereby proposing AI-based technologies that can operate with low power consumption across various environments. Efficiency optimization of AI models—gaining attention recently due to power consumption concerns—can be divided into two approaches: software-centric model compression and hardware-centric semiconductor accelerator technologies. However, since these approaches have typically been developed independently, applying compressed models in practice has often resulted in reduced computational speed. Professor Kim conducted integrated research to develop lightweight AI techniques that take hardware characteristics into account, while simultaneously designing a dedicated semiconductor chip to efficiently support them. This technology supports AI lightweight models with “variable bit precision,” which adjusts the number of bits used in computation according to the required accuracy level or hardware resource constraints. The system uses a single accelerator circuit to handle these models, enabling efficient support for variable precision with a simpler computational unit structure than before. In addition, Professor Kim challenged the conventional belief that achieving high computational accuracy requires floating-point units—which are large in chip area and consume significant power—and demonstrated that integer arithmetic units can achieve the same level of accuracy. These research results were published in the IEEE Journal of Solid-State Circuits in June 2022 and presented at the International Conference on Learning Representations (ICLR) in May 2023. Professor Kim stated, “I will continue to focus on designing low-power integrated circuits that minimize energy consumption to contribute to the sustainable development of AI,” and added, “I expect this research to serve as a core foundational technology enabling AI computation in mobile environments where power efficiency is critical.” Professor Jaejoon Kim’s research team [Provided by the Ministry of Science and ICT.

Development of RIS Technology Compatible with Commercial Satellite Frequencies Installable on Skyscrapers without the Assistance of Additional Equipment Based on Transparent Materials, Performance has been Verified by Attaching to a Moving Vehicle [Edaily Reporter Hyunah Kim] We still have to wait at least 5 years for the commercialization of 6G where satellites become base transceiver stations, but technology that enables 5G operation at satellite frequencies has been recently developed and gaining attention. This technology is expected to maintain connectivity in various environments, including skyscrapers above 60-stories high, KTX trains cruising over the speed of 300km/h, and Urban Air Mobility (UAM, Small aircrafts used in urban areas, anticipated to become a new revolution in transportation). KT(CEO: Youngshub Kim), along with the Seoul National University (SNU) Department of Electrical and Computer Engineering (ECE) research team announced last 27th that they have developed Reconfigurable Intelligent Surface (RIS) technology that operates at 5G wireless communication frequency bands (3.5GHz) and KT Skylife satellite frequency bands (12GHz). This technology was unveiled by KT at the MWC 2024. Usage on Outer Walls of Skyscrapers RIS technology induces the reflection and transmission of electromagnetic waves in desired directions. For example, if we attach RIS to the outer walls of skyscrapers, it enables the transmission of high frequency waves into the building, making it possible for receiving & transmitting such signals without exposing wireless communication equipment outside of the building. Such technology can help the construction of network infrastructures more efficiently. The RIS technology developed by KT and the research team of SNU ECE Department’s professor Jungsuek Oh, transmits not only 6G candidate frequencies, but also 5G wireless communication frequencies and KT Skylife satellite frequencies, through a small surface area. Until now, KT has been developing RIS materials and technologies that operate in the mmWave frequency bands (28GHz) and 6G candidate frequency bands (8GHz, 15GHz). On the other hand, the commercialization of RIS technology for 5G communication seemed to be more challenging, since it required samples with larger surface area, due to the relatively lower frequencies of the 5G frequency bands. However, the newly developed RIS simultaneously obtained a wide transmission angle of over 90 degrees (negative refraction angle) and a high transmission rate by utilizing novel structures and surface engineering technologies. The wide transmission angle helps in improving the quality of indoor wireless transmission. Also, due to the transparency of the RIS material, it can be easily installed by attaching it to a vehicle’s window or manufacturing it as an all-in-one structure. Performance Testing on Car Windows In order to verify the versatility of their RIS technology, the KT and SNU research team attached the RIS to a vehicle window moving on a freeway. They observed that signals directed perpendicular to the vehicle’s moving direction, such as 5G waves from communication towers of the outskirts of the freeway or KT Skylife satellite signals, were refracted into the vehicle. KT will continue to collaborate with equipment manufacturers, material & component companies to apply this RIS technology to building & vehicle windows. In addition, it plans to continuously explore key technologies applicable to various wireless network environments such as RIS to secure technological leadership in the field of 6G wireless communication. Professor Jungsuek Oh from the ECE department of SNU stated, "While most research and demonstrations on conventional transparent RIS have focused mainly on improving penetration loss, our RIS technology and validation have demonstrated for the first time that even under constraints of transparent materials and processing conditions, radio waves can be refracted in arbitrary directions, significantly improving communication coverage." Executive Director Jongsik Lee of KT Network Research Institute stated, "We anticipate that this RIS technology will enhance wireless service quality within moving vehicles. We aim to strengthen our leadership in new wireless communication technologies and contribute to the establishment of 6G networks."

The number of high school graduate students has decreased from 760 thousand in the year 2000 to 440 thousand in the year 2022, and this decreasing trend is predicted to continue in the future. Assuming the enrollment quota of top universities remain relatively constant, this will lower the average academic level of students enrolling to such schools. The government is expected to announce an increase in the medical university enrollment quota sooner or later. This seems to be an adequate policy for the medical health of our citizens, what kind of effect will this have on supplying enough high-quality personnel for cutting-edge fields such as semiconductor technology? Let’s assume the government increases the medical university quota by 2000, which is similar to the SNU science & engineering quota of 1800. Considering that most Korean high school students prefer medical universities to other options, many students who would have enrolled to SNU may apply to medical universities when medical schools increase their capacity. This could lower the academic level of students enrolling to SNU science & engineering majors, and the effect will sequentially show in other universities, too. In China and India, who are competitors of Korea in the semiconductor industry, many academically excellent students are applying to engineering universities instead of medical schools, and we must remember that they are likely to be competitors of our future engineers. Recently, the government, universities, and tech-companies have been working together to increase the supply of engineers in the semiconductor industry by creating new college platforms such as the School of Transdisciplinary Innovations, along with departments specialized in semiconductor technology, and schools that guarantee employment to tech-companies. Some tech-companies even go further, creating programs where foreign students receive a scholarship, get educated in Korean universities, and are employed afterwards. However, the quality of supply also has to be considered along with the amount of supply, since cutting-edge fields such as the semiconductor industry require expertise. Therefore, we need students with high academic capacity to continuously apply to such semiconductor-based college programs. Also, semiconductor technology requires transdisciplinary understanding of a variety of fields, including mathematics, physics, and software. Therefore, educating and training personnel in the semiconductor industry is a time-consuming project, and the importance of engineers with master’s or doctoral degree is significant. In Taiwan’s TSMC, the rival competitor of Samsung Electronics, approximately half of the personnel have a master’s degree, while most of Samsung’s personnel are based on engineers with a bachelor’s degree. In order to encourage the enrollment of top students in STEM fields, it is necessary to provide more stable benefits than currently offered, so that students do not feel relatively disadvantaged in terms of salary or stability. Recently, the government has decided to expand the Presidential Science Scholarship Program not only to undergraduate students but also to graduate students, aiming to boost the pride of scholarship recipients, which is a very commendable decision. I also recommend that companies introduce significant incentive systems for outstanding candidates, departing from the existing wage structure that pays similar salaries to all new hires. Companies should instill confidence in their researchers by extending retirement age, allowing them to work for the company for a longer period. Additionally, in order to elevate at least one or two graduate schools in Korea to a world-class level, there should be a significant increase in research funding. It is also important to increase special scholarships for students in advanced fields, and to hire administrative staff so that professors and graduate students can focus solely on research without being burdened by administrative tasks. While expanding the capacity of medical schools is necessary, it is also crucial to have a national discussion about educating and training future experts in advanced fields.
