Yangtze Reminiscence Applied sciences Corp, the Chinese language reminiscence chip producer, has been stockpiling overseas gear for months in anticipation that the US is getting ready to kneecap one in every of China’s nationwide champions.
4 YMTC staff mentioned the corporate had been getting ready for Washington to impose export controls, as US lawmakers urged the Biden administration to punish the state-backed firm for allegedly serving to the Chinese language army and violating commerce restrictions by supplying chips to Huawei, the Chinese language telecoms firm.
“We’ve been doing every little thing attainable beforehand to help current manufacturing traces, reminiscent of stockpiling every kind of apparatus,” mentioned one senior YMTC engineer.
These considerations materialised on Friday when the US unveiled tough export controls concentrating on the Chinese language chip trade, together with YMTC, suggesting the Wuhan-based firm may confront extra bother.
YMTC has lately emerged as a nationwide champion in China’s drive to construct a home chip trade. President Xi Jinping visited its amenities in 2018 to point out help. It boasts Rmb220bn ($30bn) in funding with monetary assist from Hubei province and a nationwide fund.
The brand new US restrictions hit YMTC by banning the availability of sure American expertise wanted to provide superior Nand reminiscence chips.
Business consultants mentioned it was unclear how YMTC may maintain its speedy advances. Highlighting the influence of the restrictions, KLA Corp, Lam Analysis and Utilized Supplies — three high US semiconductor toolmakers — have halted gross sales and providers to YMTC, in keeping with three YMTC staff.
In one other transfer final Friday that acquired much less consideration however may show much more painful for YMTC, Washington put the chipmaker on its “unverified checklist”. The registry consists of entities for which the US has not been capable of conduct end-user checks to confirm that American expertise is getting used for authentic functions and never, for instance, being diverted for army use.
On the identical time, the US authorities carried out a brand new coverage underneath which addition to the unverified checklist begins the clock on a 60-day deadline for the end-user checks to be accomplished. If they aren’t, the corporate is extremely more likely to be added to the “entity checklist”, which might successfully stop US firms from offering YMTC with expertise for its much less superior chips.
“Being added to the unverified checklist was a nuisance. Now it ought to be terrifying,” mentioned Gregory Allen, a expertise knowledgeable at Washington-based think-tank CSIS.
Package Conklin, a former US intelligence official and China knowledgeable on the Atlantic Council, estimated the probabilities of YMTC being added to the “entity checklist” at 99 per cent.
“Over the previous few years, the Chinese language commerce ministry has stonewalled the US commerce division by not permitting end-user checks to happen. It will be a major coverage change by Beijing in the event that they determined to play ball,” mentioned Conklin.
Other than the potential for being added to the entity checklist, YMTC faces different critical difficulties.
“YMTC can nonetheless function and ship chips as they’ve stocked up supplies and elements,” mentioned Brady Wang, an analyst at analysis group Counterpoint. “It will be tough for them to develop manufacturing as the brand new gear shouldn’t be obtainable.”
One worker mentioned YMTC had sufficient inventory of supplies reminiscent of wafers and elements for gear repairs to final a yr. However that will solely be provided that “there aren’t any enormous points that may solely be fastened by tech employees from overseas firms”.
YMTC didn’t reply to a request for remark.
As YMTC has received international market share, it has come under scrutiny in Washington over considerations that it’ll use Chinese language authorities subsidies to promote chips under market worth, placing stress on non-Chinese language rivals reminiscent of Micron Know-how within the US.
YMTC has been cautious to not expose many particulars about its technological developments.
However one innovation it has pioneered is using “Xtacking” expertise, which simplifies the manufacturing course of for superior reminiscence chips, giving YMTC a path into the Nand chip market dominated by Samsung and Micron.
YMTC’s market share of worldwide Nand manufacturing grew from 1 per cent in 2020 to five per cent in 2021, in keeping with France-based analysis firm Yole Improvement.
Whereas its market phase is comparatively small, YMTC has been courting high-profile shoppers. Apple told the Financial Times final month that it was contemplating utilizing YMTC chips in some smartphones.
Apple didn’t reply to a request for remark about whether or not it was revising its plans within the wake of the brand new export controls.
Business insiders mentioned that together with the restrictions, YMTC’s heavy reliance on authorities help difficult its path to profitability.
“YMTC has been making losses and depends closely on authorities funding for analysis and manufacturing growth,” mentioned one Shanghai-based analyst.
“The federal government needs YMTC to grab extra market share and make expertise breakthroughs, albeit struggling to revenue.”
The chipmaker additionally has restricted choices to answer Washington.
“The US authorities is making an attempt to place YMTC’s most superior Nand manufacturing amenities out of enterprise,” mentioned Allen of CSIS in a report this week.
“It is going to be particularly tough for Chinese language firms to evade these gear export controls.”
