Micron plans to expand HBM production capacity to approximately 100,000 wafers per month by the end of the year
According to Electronic News on September 3, Micron plans to double its high bandwidth memory (HBM) production capacity compared to last year, with a maximum addition of 60,000 wafers per month by the end of this year. Insiders say that Micron's HBM output was about 40,000 to 50,000 wafers per month last year, and it is expected to reach about 100,000 wafers per month by the end of the year, narrowing the gap with Samsung Electronics and SK Hynix.Micron is increasing procurement orders from multiple HBM equipment suppliers, with production bases mainly in Taiwan and Singapore, continuously introducing equipment. Currently, the output is mainly HBM3E 12-layer, with HBM4 12-layer accounting for about 20% to 30% at the beginning of this year, which may rise to as high as 50% by the end of the year. HBM4 12-layer will be used in NVIDIA's latest AI accelerator, Vera Rubin, and Micron has started mass production of this product since the second quarter of this year.Micron CEO Mehrotra stated in the Q3 earnings call for fiscal year 2026 in June this year that the ramp-up speed of HBM4 12-layer mass production is about twice that of HBM3E 12-layer, and cumulative revenue from HBM4 shipments has exceeded $1 billion. The industry believes that Samsung and SK Hynix each have HBM production capacities of about 150,000 to 200,000 wafers per month. Counterpoint data shows that in Q2 of this year, the global HBM market shares were SK Hynix 50%, Samsung 32%, and Micron 18%. Micron is also preparing related investments in Hiroshima, Japan.
