Micron Breaks Floor on Its $15 Billion EUV DRAM Fab within the U.S.

Micron this week broke floor on its modern reminiscence manufacturing facility close to Boise, Idaho. The corporate will make investments $15 billion in its new fab as part of its bold plan to speculate $40 billion in its U.S.-based manufacturing capacities by the top of this decade in addition to spend $150 billion on new fabs by 2030 globally.

Micron’s upcoming modern fab will produce DRAM and will probably be a slightly colossal manufacturing facility. At build-out, when the fab is totally outfitted with instruments, its cleanroom area will attain 600,000 ft2 (55,700 meters2), which is about two instances bigger in comparison with cleanroom area at GlobalFoundries’ Fab 8 and which is corresponding to cleanroom area at large fabs operated by Micron’s rivals Samsung and SK Hynix is South Korea. Basically, Micron will function one of many largest semiconductor manufacturing services within the U.S.

The brand new fab will probably be positioned adjoining to Micron’s R&D heart and headquarters close to Boise, Idaho, which is able to deliver collectively scientists, course of know-how builders, and manufacturing engineers in a single location, one thing that guarantees to hurry up time-to-yield and time-to-market for superior DRAMs. 

“With this facility, Micron will intently couple R&D and manufacturing, offering synergies that can allow us to speed up the manufacturing ramp of superior reminiscence know-how,” mentioned Sanjay Mehrotra, president and CEO of Micron.

Micron is at the moment prepping the location for the brand new fab and plans to start building in early 2023 in a bid to start out bringing cleanroom area on-line steadily beginning in 2025. The power will probably be outfitted with trendy deep ultraviolet (DUV) and excessive ultraviolet (EUV) lithography instruments and can make reminiscence utilizing considered one of Micron’s superior EUV-enabled manufacturing nodes. The corporate intends to start out fabbing DRAMs at its new facility generally in 2025 after which ramp up manufacturing to the full capability within the following years. 

At current it’s laborious to guess which fabrication course of will probably be adopted on the new fab. Contemplating the truth that Micron is anticipated to start out DRAM manufacturing utilizing its first EUV-enabled manufacturing technology (1γ) generally in mid-2023 – early-2024, it’s seemingly that the fab close to Boise, Idaho, will undertake the corporate’s second EUV-enabled course of (1δ). But, that is an informed guess (primarily based on recurring introduction of recent DRAM nodes each 18 months or so) at this level.

Micron intends to make 40% of its world DRAM output in America in 2030s, a rebalance that the corporate has not finished in many years. Due to this fact, along with Micron’s new fab close to Boise, Idaho, the corporate plans to construct a yet one more DRAM facility within the U.S. At present the corporate is within the remaining levels of its choice course of for one more website in America. 

Micron will make investments $15 billion within the new manufacturing facility close to Boise, Idaho. The corporate additionally plans to get incentives from the native and state authorities and assist from the federal authorities enabled by the CHIPS and Science act signed into legislation final month.

“The funding, made doable by the anticipated grants and credit offered by the CHIPS and Science Act, additionally enhances Micron’s provide chain resilience and can set up a brand new strategic functionality for the U.S.,” mentioned the top of Micron.

It’s noteworthy that Micron shouldn’t be the one DRAM maker to start out constructing new reminiscence fabs when demand for each 3D NAND and DRAM is down. Final week SK Hynix began to expand its M15 site with its new M15X constructing as the corporate is making ready for elevated DRAM demand beginning in 2025.
