Micron Phase 2 Confirms Sanand as a Core Node in Its Global Memory Supply Chain
Micron Technology has announced a second-phase capital expansion at its Sanand semiconductor OSAT facility in Gujarat, taking the facility's packaging capacity from its current rate of approximately 14 million units per week to more than 30 million units per week by the end of 2027. The phase-2 investment, which adds a second clean room floor, new packaging equipment lines for LPDDR5X low-power DRAM, and a substantially expanded test floor, represents Micron's confirmation that the Sanand facility has performed to expectations in its initial operating phase and merits a capacity doubling. The expansion also adds a high-bandwidth memory assembly line that will handle HBM3E packages for AI training and inference accelerator cards, bringing Micron's most technically demanding current product line into the India facility for the first time.
LPDDR5X and the Mobile Market Connection
The largest volume addition from the phase-2 expansion is the LPDDR5X packaging line, which addresses the memory type used in flagship smartphones from Apple, Samsung, and Chinese Android OEMs and in high-performance laptops. LPDDR5X operates at data rates up to 8,533 MT/s and requires the low-inductance, low-capacitance package substrates and tight assembly tolerances that Micron is installing in the second clean room floor. India's own smartphone market consumes tens of millions of units of LPDDR5X-equipped devices annually through imports, and while the Sanand facility's output primarily enters Micron's global supply chain rather than serving only the Indian market, the expansion connects India's manufacturing capability to the products that Indian consumers buy every day. The LPDDR5X expansion also positions Sanand to serve the growing number of Indian electronics assemblers that are producing memory-equipped devices under PLI incentive programmes.
HBM3E Line and the AI Infrastructure Connection
The addition of a high-bandwidth memory assembly line for HBM3E is the most technically ambitious element of the phase-2 expansion. HBM packaging involves stacking multiple DRAM dies using through-silicon via interconnects and assembling the stack onto a base die, all within extremely tight dimensional tolerances, before mounting the completed package on a silicon interposer alongside a GPU or AI accelerator chip. HBM is the memory technology that enables the compute density of NVIDIA's H-series and B-series GPU clusters, and demand for HBM3E is currently constrained by the limited number of facilities globally that can manufacture it. Adding HBM3E capability to the Sanand facility positions Micron to route a portion of its most value-intensive memory packaging through India, increasing the economic contribution of the facility per unit output and developing a workforce with expertise in the most advanced assembly process in the memory industry.
Cumulative Investment and India Policy Context
The phase-2 expansion brings Micron's total announced investment in India since 2023 to over USD 2.5 billion, making it the largest single foreign direct investment in India's semiconductor manufacturing sector to date. The expansion was supported by continued engagement with the India Semiconductor Mission and the Gujarat government, whose incentive frameworks covering capital subsidy, land, and infrastructure provision have supported the economics of both the initial investment and the expansion. Micron's phase-2 decision is a significant signal to other memory and logic chip companies evaluating India OSAT investments, demonstrating that an international semiconductor company has operated a new India facility for long enough to make a doubling investment, which is the strongest possible validation of the operating environment.
