Emphasis on "may". This report is confused enough that we didn't post it when it dropped out of a feedreader a couple weeks ago but now with NVDA about to report, a heads up.

Reports: TSMC Accident Destroys Tens of Thousands of Nvidia GPU Wafers
After the Great Cryptographic GPU Shortage of 2017 sent GPU prices into the stratosphere, the slow decline through 2018 was a welcome return to normal. Now, we may see fresh shortages and higher prices thanks to a reported manufacturing problem at TSMC.
The following is a quote from a report by the Chinese site Expreview:
Today, TSMC has been experiencing a security incident. This time, the wafer was contaminated by unqualified raw materials. It is estimated that it will lose tens of thousands of wafers, affecting the 16/12nm process of the main revenue, NVIDIA GPU and many mobile phone chip manufacturers.The use of the word “security” is a bit confusing in this context; it may be a mistranslation. Nothing else in the story refers to a specific security incident. Instead, the story states that wafers have been contaminated by “unqualified raw materials.”
The incident supposedly occurred at Fab 14 in Nanke Technology Park. The loss of tens of thousands of wafers — if that figure is accurate (and we’re trusting Google with the mechanical translation) — would represent a significant chunk of a typical fab’s monthly output. It could even encompass the entirety of a fab’s output for that period of time, depending on just how many wafers “tens of thousands” actually refers to. Supposedly chemicals were used in the manufacturing process that were either inappropriately purified or simply the wrong product.TSMC has not yet made an announcement about the scope or scale of the impact. While Nvidia issued an earnings warning today (we’ll take that up separately), they did not mention any reports of damage to TSMC in the document. This is a very serious claim, but the exact impact and overall contours remain unclear....MORE
