Core Viewpoint - Samsung Electronics is accelerating the development of 1nm wafer fabrication technology to create a competitive advantage, as it currently lags behind TSMC in the 2nm and 3nm processes [1][2]. Group 1: Samsung's Development Plans - Samsung has initiated the development of 1nm technology, selecting researchers from its 2nm projects to form a dedicated team [1]. - The company aims to mass-produce 1.4nm technology by 2027, with plans for 1nm production set for after 2029 [1]. - The development of 1nm technology requires new design concepts and the introduction of next-generation equipment, such as High-NA EUV lithography machines [1]. Group 2: Competitive Landscape - TSMC announced plans to start production of 1.6nm technology in the second half of 2026, bridging the gap between 1.4nm and 2nm processes [2]. - This move by TSMC is seen as a response to the rapidly changing demands of the AI semiconductor market [2].
