'At least' 6.5 exabytes lost after contamination hits Kioxia/WD 3D NAND fabs

Production at Kioxia and Western Digital's 3D NAND fabrication facilities in Japan is being disrupted by chemical contamination, with at least 6.5 exabytes of capacity lost.
The two companies operate a joint venture which has six fabs at Yokkaichi in Mie province, employing some 8,000 people, and a seventh fab at Kitakami in Iwate province.
A Kioxia statement says that, in late January, a chemical used in 3D NAND production was found to be contaminated and production was affected. Measures are being taken to restore normal production. Manufacture of 2D NAND is not affected.

Western Digital Corp confirmed soon after that production operations at both the Yokkaichi and Kitakami joint venture flash fabrication facilities were affected.

WD said in a statement:
Western Digital's current assessment of the impact is a reduction of its flash availability of at least 6.5 exabytes. The company is working closely with its joint venture partner, Kioxia, to implement necessary measures that will restore the facilities to normal operational status as quickly as possible.
The contaminated chemical substance and its supplier were not identified.

Wells Fargo analyst Aaron Rakers pointed out that WD takes about 40 per cent of the JV's output and, by extension, Kioxia will also suffer a production capacity loss, meaning a potential reduction of production output of up to 16EB.
WD shipped around [6]24EB of NAND in 2021's fourth quarter , meaning it's potentially lost the equivalent of 27 per cent of that quarter's output. Clearly its NAND revenues in the current quarter will be reduced by this production loss and the same will be true for Kioxia.
Rakers estimated NAND demand last quarter was about 160EB. Assuming that demand level carries through to the current quarter, up to 10 per cent of that demand won't be satisfied and 3D NAND prices will probably rise as a result.

Before this incident, research house TrendForce had forecast that the NAND flash market would see a slight oversupply the entire year and average price from Q1 to Q2 would face downward pressure. "The impact of WDC's material contamination issue is significant and Samsung's experience during the previous lockdown of Xi'an due to the pandemic has also retarded the magnitude of the NAND flash price slump," it said.
In addition, according to TrendForce, the combined WDC/Kioxia NAND Flash market share in the 3Q21 was as high as 32.5 per cent.

The analyst suggested: "The consequences of this latest incident may push the price of NAND Flash in Q2 to spike 5~10 per cent."
If the affected chemical was a gas or liquid then tanks used to store it, and pipes used to deliver it around the plant and into machines, will have to be emptied and cleaned, and then tanks restocked. The machines themselves will have to be cleaned. This will take time.
Rakers pointed out: "It is unclear to what extent the chemical impacts could have affected the fab manufacturing equipment."
In other words, the lost production capacity could be greater than 16EB and the period needed to regain normal operations longer than otherwise.

Kioxia are celebrating the 35th anniversary of their previous incarnations invention of NAND flash and they do with "accidentally contaminating" their fab, its somehow very convenient that this happens as flash prices fall...
I'm getting too cynical...
ShadowSystems
At what point will the price increases come back down to pre-shortage levels? Never, because the manufacturers have seen that the public will pay for the stuff at the higher prices, so there's no incentive to bring them back down.
"Hey Bob, how about you sabotauge your output capability to create a shortage of your stuff, I'll do the same for my stuff, then we both raise our prices as a result? We'll get rich!"
"Hey Bill, I like that idea, but here's a better one. Let's just SAY that there was sabotauge, like a chemical contamination or something, and then use that as the excuse to raise prices? We'll get richer!"
"Bob, you're a genius!"
*Sigh*
I'm getting far too cynical for my own damned good... =-/
