Core Viewpoint - TSMC is exiting the GaN foundry business and restructuring its wafer fabs to optimize operations and reduce costs, while focusing on advanced packaging and internal development of EUV mask protection films [2][4][6]. Group 1: TSMC's Strategic Moves - TSMC will close its 6-inch GaN foundry in Hsinchu Science Park within two years and integrate its three 8-inch fabs to address labor shortages and improve asset utilization [2]. - The 6-inch fab will be repurposed for CoPoS advanced packaging, while the 8-inch fabs will focus on internal production of EUV mask protection films to reduce reliance on ASML and its supply chain [4]. - TSMC's investment in advanced process nodes has been significant over the past decade, but the high costs associated with EUV technology are prompting a shift in strategy to enhance yield and cost efficiency [4]. Group 2: Importance of Mask Protection Films - EUV technology requires new mask and protection film methods, as traditional organic films lack the necessary transparency and stability for EUV processes [5]. - TSMC's proprietary protection films are expected to optimize workflows, improve yields, expand capacity, and reduce costs, thereby enhancing profitability and maintaining its competitive edge [5]. - The transition to in-house mask protection film development is crucial for TSMC as it moves towards 2nm processes and expands CoWoS packaging technology [5]. Group 3: Market Dynamics and Competition - The exit from the GaN sector highlights intense price competition from Chinese competitors in the third-generation semiconductor market [6]. - Global IDM manufacturers, including Texas Instruments and Infineon, are also expanding their internal GaN capacities, indicating a growing focus on this technology [6].

Core Viewpoint - The decision of Lee Ji-hoo, the son of Samsung Electronics' leader Lee Jae-yong, to renounce his U.S. citizenship and return to South Korea for military service has sparked significant public interest and discussion [2][4]. Group 1: Decision and Background - Lee Ji-hoo has officially given up his U.S. citizenship to fulfill his military obligations, with an appointment as a junior officer in the South Korean Navy starting December 1 [4]. - He will serve for a total of 39 months, beginning with an 11-week training course at the Korean Naval Academy, which includes military drills, combat skills, and leadership training [4]. - Lee Ji-hoo was born in New York in 2000 and has dual citizenship, having completed his high school education in Canada and further studies at Sciences Po in Paris [5]. Group 2: Implications and Context - The choice to serve as an officer extends his service period significantly, as mandatory military service in South Korea is at least 18 months for healthy males [7]. - Historically, many male descendants of Samsung's founder have avoided military service due to health issues or other reasons, making Lee Ji-hoo's decision particularly noteworthy [6][7]. - Lee Ji-hoo had previously postponed his military service due to his extended overseas education [8].

Core Viewpoint - The article discusses the production ramp-up of the iPhone 17 series at Foxconn's Zhengzhou facility, highlighting the increased demand for temporary workers and the rising wages associated with this demand.
