Micron's Tongluo fab capacity may exceed estimates with EUV upgrades

作者 PulseAugur 编辑部 · [10 个来源] ·

Micron is acquiring the PSMC P5 Tongluo fab in Taiwan, with plans to significantly expand its wafer output by 2028. The facility's Section B is being designed for EUV compatibility and advanced HBM manufacturing, potentially supporting future DRAM nodes like HBM3E and HBM4E. While Section A is being converted for existing processes, the overall expansion is expected to increase Micron's capacity beyond initial estimates. AI

影响 Micron's expanded HBM production capacity could influence the supply chain for AI accelerators and high-performance computing.

排序理由 Analysis of a major semiconductor fab acquisition and expansion impacting future memory production capacity.

    Section B could also be larger than previously assumed. If Micron applies a similar cleanroom optimization strategy there (which is likely the case), maximum capacity could reach roughly higher than 40-45kwspm previously assumed. (7/10)

    That means Section B could support 1b for HBM3E/HBM4, or potentially 1γ for HBM4E.

    That means Section B could support 1b for HBM3E/HBM4, or potentially 1γ for HBM4E. This matters because EUV compatibility gives Micron more flexibility for future DRAM and HBM nodes. This also give additional space for Micron to conduct more node migration and increase bit

    Section B is different.

    Section B is different. The cleanroom has not broken ground yet, so it is unlikely to come online before the end of 2027. But because Micron can design it from scratch, it should be built to support EUV and advanced HBM manufacturing. (3/10)

    The site has two key sections: Section A and Section B.

    The site has two key sections: Section A and Section B. Section A already exists and is now being converted for likely Micron’s 1b DRAM process. Because it is not EUV-compatible, 1b is a practical fit for the existing cleanroom setup with proper equipment from Micron in coming

    Earlier this year, Micron announced it would acquire PSMC’s P5 Tongluo fab in Miaoli, Taiwan—the process has officially begun. At first glance, this looked like a straightforward legacy logic/memory fab acquisition. But the details worth a close look. (1/10) 🧵 https://t.co/6OQyI…
