전기끊기고 반도체 뺏긴 세계 반도체 1위였던 콧대 높은 대만의 경제가 몰락한 진짜 이유

A research team led by Professor Kim Dae-hyun of Kyungpook National University has broken the 700GHz barrier for Gallium Nitride (GaN) semiconductors for the first time in the world. We will now explain why this number—742GHz—has shaken the entire world. Unveiled at the VLSI Symposium 2026, one of the world's top three semiconductor conferences, this achievement marks a milestone in which Kyungpook National University in Daegu has shattered a barrier that even the United States, Japan, and Taiwan had failed to overcome for over a decade. We shed light on the career and determination of Professor Kim Dae-hyun, who returned to his alma mater after working as a postdoctoral researcher at MIT, at Teledyne (a key U.S. defense company), and at SEMATECH. We delve into why this technology is the heart of 6G communication and the core of K-Defense, and explore its significance for South Korea, which relies on imports for 98.9% of its defense semiconductors. #Semiconductor #GaN #GalliumNitride #KyungpookNationalUniversity #ProfessorKimDaehyun #742GHz #WorldFirst #6GCommunication #DefenseSemiconductor #KDefenseIndustry #VLSISymposium #CompoundSemiconductor #Economy #Economics #EconomicStudy #SemiconductorWar #SouthKoreanTechnology #Patriotism #Tech #ScienceAndTechnology References and Sources Edaily - Kyungpook National University Develops World's First GaN Semiconductor Breaking 700GHz...
