Report: SK Hynix Mulls Building $4 Billion Advanced Packaging Facility in Indiana
SK hynix is considering whether to build an advanced packaging facility in Indiana, reports the Wall Street Journal. If the company proceeds with the plan, it intends to invest $4 billion in it and construct one of the world's largest advanced packaging facilities. But to accomplish the project, SK hynix expects it will need help from the U.S. government.
Acknowledging the report but stopping short of confirming the company's plans, a company spokeswoman told the WSJ that SK hynix "is reviewing its advanced chip packaging investment in the U.S., but hasn’t made a final decision yet."
Companies like TSMC and Intel spend billions on advanced packaging facilities, but so far, no company has announced a chip packaging plant worth quite as much as SH hynix's $4 billion. The field of advanced packaging – CoWoS, passive silicon interposers, redistribution layers, die-to-die bonding, and other cutting edge technologies – has seen an explosion in demand in the last half-decade. As bandwidth advances with traditional organic packaging are largely played out, chip designers have needed to turn to more complex (and difficult to assemble) technologies in order to wire up an ever larger number of signals at ever-higher transfer rates. Which has turned advanced packaging into a bottleneck for high-end chip and accelerator production, driving a need for additional packaging facilities.
If SK hynix approves the project, the advanced packaging facility is expected to begin operations in 2028 and could create as many as 1,000 jobs. With an estimated cost of $4 billion, the plant is poised to become one of the largest advanced packaging facilities in the world.
Meanwhile, government backing is thought to be essential for investments of this scale, with potential state and federal tax incentives, according to the report. These incentives form part of a broader initiative to bolster the U.S. semiconductor industry and decrease dependence on memory produced in South Korea.
SK hynix is the world's leading producer of HBM memory, and is one of the key HBM suppliers to NVIDIA. Next generations of HBM memory (including HBM4 and HBM4E) will require even closer collaboration between chip designers, chipmakers, and memory makers. Therefore, packaging HBM in America could be a significant benefit for NVIDIA, AMD, and other U.S. chipmakers.
Investing in the Indiana facility will be a strategic move by SK hynix to enhance its advanced chip packaging capabilities in general and demonstrating dedication to the U.S. semiconductor industry.

Kioxia Details BiCS 8 NAND at FMS 2024: 218 Layers With Superior Scaling 
Kioxia's booth at FMS 2024 was a busy one with multiple technology demonstrations keeping visitors occupied. A walk-through of the BiCS 8 manufacturing process was the first to grab my attention. Kioxia and Western Digital announced the sampling of BiCS 8 in March 2023. We had touched briefly upon its CMOS Bonded Array (CBA) scheme in our coverage of Kioxial's 2Tb QLC NAND device and coverage of Western Digital's 128 TB QLC enterprise SSD proof-of-concept demonstration. At Kioxia's booth, we got more insights.
Traditionally, fabrication of flash chips involved placement of the associate logic circuitry (CMOS process) around the periphery of the flash array. The process then moved on to putting the CMOS under the cell array, but the wafer development process was serialized with the CMOS logic getting fabricated first followed by the cell array on top. However, this has some challenges because the cell array requires a high-temperature processing step to ensure higher reliability that can be detrimental to the health of the CMOS logic. Thanks to recent advancements in wafer bonding techniques, the new CBA process allows the CMOS wafer and cell array wafer to be processed independently in parallel and then pieced together, as shown in the models above.
The BiCS 8 3D NAND incorporates 218 layers, compared to 112 layers in BiCS 5 and 162 layers in BiCS 6. The company decided to skip over BiCS 7 (or, rather, it was probably a short-lived generation meant as an internal test vehicle). The generation retains the four-plane charge trap structure of BiCS 6. In its TLC avatar, it is available as a 1 Tbit device. The QLC version is available in two capacities - 1 Tbit and 2 Tbit.
Kioxia also noted that while the number of layers (218) doesn't compare favorably with the latest layer counts from the competition, its lateral scaling / cell shrinkage has enabled it to be competitive in terms of bit density as well as operating speeds (3200 MT/s). For reference, the latest shipping NAND from Micron - the G9 - has 276 layers with a bit density in TLC mode of 21 Gbit/mm2, and operates at up to 3600 MT/s. However, its 232L NAND operates only up to 2400 MT/s and has a bit density of 14.6 Gbit/mm2.
It must be noted that the CBA hybrid bonding process has advantages over the current processes used by other vendors - including Micron's CMOS under array (CuA) and SK hynix's 4D PUC (periphery-under-chip) developed in the late 2010s. It is expected that other NAND vendors will also move eventually to some variant of the hybrid bonding scheme used by Kioxia.

End of the Road: An AnandTech Farewell It is with great sadness that I find myself penning the hardest news post I’ve ever needed to write here at AnandTech. After over 27 years of covering the wide – and wild – world of computing hardware, today is AnandTech’s final day of publication.
For better or worse, we’ve reached the end of a long journey – one that started with a review of an AMD processor, and has ended with the review of an AMD processor. It’s fittingly poetic, but it is also a testament to the fact that we’ve spent the last 27 years doing what we love, covering the chips that are the lifeblood of the computing industry.
A lot of things have changed in the last quarter-century – in 1997 NVIDIA had yet to even coin the term “GPU” – and we’ve been fortunate to watch the world of hardware continue to evolve over the time period. We’ve gone from boxy desktop computers and laptops that today we’d charitably classify as portable desktops, to pocket computers where even the cheapest budget device puts the fastest PC of 1997 to shame.
The years have also brought some monumental changes to the world of publishing. AnandTech was hardly the first hardware enthusiast website, nor will we be the last. But we were fortunate to thrive in the past couple of decades, when so many of our peers did not, thanks to a combination of hard work, strategic investments in people and products, even more hard work, and the support of our many friends, colleagues, and readers.
Still, few things last forever, and the market for written tech journalism is not what it once was – nor will it ever be again. So, the time has come for AnandTech to wrap up its work, and let the next generation of tech journalists take their place within the zeitgeist.
It has been my immense privilege to write for AnandTech for the past 19 years – and to manage it as its editor-in-chief for the past decade. And while I carry more than a bit of remorse in being AnandTech’s final boss, I can at least take pride in everything we’ve accomplished over the years, whether it’s lauding some legendary products, writing technology primers that still remain relevant today, or watching new stars rise in expected places. There is still more that I had wanted AnandTech to do, but after 21,500 articles, this was a good start.
And while the AnandTech staff is riding off into the sunset, I am happy to report that the site itself won’t be going anywhere for a while. Our publisher, Future PLC, will be keeping the AnandTech website and its many articles live indefinitely. So that all of the content we’ve created over the years remains accessible and citable. Even without new articles to add to the collection, I expect that many of the things we’ve written over the past couple of decades will remain relevant for years to come – and remain accessible just as long.
The AnandTech Forums will also continue to be operated by Future’s community team and our dedicated troop of moderators. With forum threads going back to 1999 (and some active members just as long), the forums have a history almost as long and as storied as AnandTech itself (wounded monitor children, anyone?). So even when AnandTech is no longer publishing articles, we’ll still have a place for everyone to talk about the latest in technology – and have those discussions last longer than 48 hours.
Finally, for everyone who still needs their technical writing fix, our formidable opposition of the last 27 years and fellow Future brand, Tom’s Hardware, is continuing to cover the world of technology. There are a couple of familiar AnandTech faces already over there providing their accumulated expertise, and the site will continue doing its best to provide a written take on technology news.
So Many Thank Yous
As I look back on everything AnandTech has accomplished over the past 27 years, there are more than a few people, groups, and companies that I would like to thank on behalf of both myself and AnandTech as a whole.
First and foremost, I cannot thank enough all the editors who have worked for AnandTech over the years. T... Site Updates
