Core Viewpoint - Samsung Electronics' semiconductor foundry division is accelerating its efforts to secure orders for the 2nm process technology, collaborating with companies like Nvidia and Qualcomm, as it aims to catch up with TSMC, which has already secured significant orders from major clients like Apple and Nvidia [1][2]. Group 1: 2nm Process Development - Samsung is currently in the final stages of evaluating the performance of its 2nm process for Nvidia's GPUs and Qualcomm's application processors [1]. - The yield rate for Samsung's 2nm process is reportedly over 40%, while the yield for its 3nm process has exceeded 60%, providing a foundation for further improvements in the 2nm process [2][3]. - The GAA (Gate-All-Around) technology, which Samsung first introduced in its 3nm process, is designed to minimize leakage current and enhance semiconductor performance compared to traditional FinFET technology [1]. Group 2: Competitive Landscape - TSMC has successfully begun mass production of 2nm technology in Arizona, having already secured orders from Apple and AMD for their next-generation AI accelerators [3]. - The demand for 2nm technology is expected to be significantly higher than that for 3nm, as indicated by TSMC's recent earnings call, where it reported that revenue from advanced processes below 3nm has surpassed 22% [2][3]. - Industry analysts suggest that geopolitical risks are prompting global tech giants to diversify their manufacturing partners beyond TSMC, which may benefit Samsung in securing more orders [2].
