Everyone Is Announcing Capacity. Nobody Is Announcing The Number That Decides It.
Nobody is announcing yield — and only one of those decides whether the wafers are worth selling.
imec Says Fabs Can't Measure Every Wafer. So 95% Are Predicted.
In a fab running virtual metrology, only one to five percent of wafers are physically measured. The rest get a number anyway — predicted by a model that reads the process tools rather than the wafer: gas flows, RF power, chamber pressure, roughly a thousand sensor variables per run, turned into a thickness, a line…
The Chip So Big They Can't Throw the Broken Part Away
Every chip factory on Earth runs on the same rule: cut the wafer into hundreds of chips, test them, and throw the broken ones away. That rule is what "yield" means.
Your Fab's AI Goes Blind on the 2nm Node — Here's Why
Your fab's new AI spots defects better than any engineer — and on the brand-new node it goes almost blind. Not because the model is bad, but because every one of these systems learns from history: thousands of wafers, labelled defects, known-good outcomes.
The 6-Inch Wafer That Every AI Data Center Depends On
NVIDIA just put $2 billion into a chip factory that runs six-inch wafers — not the twelve-inch wafers the rest of the industry moved to decades ago. The reason is that the chips moving data between processors inside an AI data center aren't silicon at all: they're indium phosphide, and the lasers built on it…
Intel's $11 Billion Mirage
Intel just posted an $11B loss — and the stock jumped ~12%.
Two Machines, One Chip Layer
Intel just ran the same 18A chip layer on a ~$380M High-NA EUV machine AND a standard scanner — and got matched yield (first high-volume High-NA logic ever, July 15).
AI Now Lets Chip Fabs "Measure" Wafers They Never Touch (Virtual Metrology)
Chip factories physically measure only about 3 wafers in 100. For the other 97, an AI called virtual metrology predicts the exact dimension straight from the process tool's own sensor "fingerprint" — pressure, power, gas flow, hundreds of signals per wafer — in milliseconds, with no measurement step and no throughput hit.
This $400M Machine Prints Chips in a Focus Thinner Than a Virus (Intel Went First)
This week the most expensive machine humans have ever built made its first real products — and almost nobody noticed. It's called High-NA EUV: a $400-million lithography system, twice the price of a normal chip printer, and Intel just became the first company on the planet to ship commercial chips made on it.
NVIDIA's Chip Is Finished — It Still Can't Ship (The Real AI Bottleneck)
NVIDIA's fastest AI chip has been finished for months — and it still can't ship. The reason isn't the 2-nanometer transistor everyone's racing toward; it's the very last step, advanced packaging.
The Real AI Shortage Is Memory, Not GPUs
Your next laptop just got about 20% more expensive. The reason is HBM, and HBM is a yield problem.
