I wasnt supposed to be able to tell you about this until Monday, but it looks like the news leaked early so IMFT gave us the green light.
Intel and Micron jointly formed IMFT (Intel-Micron Flash Technologies), LLC back in 2006. The two companies share production from the venture. Intel gets 49% of IMFTs flash production and Micron gets 51%.
In the usual Intel tradition, IMFT aggressively scales process technology to be competitive. The company started manufacturing at 72nm, spent 2008 at 50nm and just last year scaled down to 34nm. The latter is what found its way into Intels X25-M G2 as well as Microns soon-to-be released RealSSD C300.
Today IMFT is announcing that it has begun sampling 2-bits-per-cell MLC NAND flash manufactured using 25nm transistors. The company believed it had a 6 month head start over the competition in 34nm, and now believes that with 25nm NAND its roughly a year ahead of anyone else.
Volume production will happen sometime in Q2, with products shipping before the end of the year. In my last SSD article I mentioned that Intels 3rd generation X25-M would be shipping in Q4 at 160GB, 320GB and 600GB. These drives will use IMFTs new 25nm flash.
The first 25nm product is an 8GB (64Gbit) 2-bits-per-cell MLC NAND flash. A single 8GB die built on IMFTs 25nm process has a die size of 167mm2. Immersion lithography is apparently necessary to produce these 25nm NAND devices, but the extent is unclear. This is technically Intels first device that requires immersion lithography to manufacture.

600 GB SSD.
167mm2 is 12.92x12.92 mm, about 1/2 x 1/2 inch for us residents of Rio Linda ....
