The callKLA's silicon tools misread compound wafers, which is a real opening, but the buyers are a handful of European specialty fabs and nobody has founded the company yet.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the restraints.
  1. D1Power electronics for EVs and AI datacentres and the lasers for optical links move onto silicon carbide, gallium nitride and indium phosphide wafers that KLA's silicon tools misread.
  2. D2Chips Act and industrial subsidies build new specialty fabs in Europe, each needing in-line measurement priced for a 200mm line.
  3. R1The serviceable market is under $1B worldwide and about $55-120M in Europe, so the leader may never get big enough.
  4. R2Exits are small: Camtek bought FRT for $100M on about $30M of revenue, and the likely winner does about $50M of revenue for a $200M exit.
  5. R3No early company exists yet: the one existing candidate looks too late and too small, and HIDRA Vision is not yet incorporated.
  6. C1ST's Catania 200mm silicon carbide campus starts production, the first integrated European SiC line and one KLA's 300mm data does not cover.2026

  2. 2At least one European metrology startup targeting compound-semiconductor or photonics fabs (not leading-edge silicon) closes a Series A of EUR 5M or more by end of 2029, having secured at least one fab co-development agreement with a European specialty fab.Dec 2029 · open
  3. 3One closes a €5M+ Series A with a named fab partner; Invisix's €20M seed shows a European metrology seed of that size is fundable.Dec 2029 · open

What changedthe record, newest first
  • 22 Jun 2026The reason a metrology startup can get in against KLA is that KLA's whole calibration advantage is built for silicon and is in the wrong substrate for compound-semi and photonics fabs, and KLA would rather sell old tools cheap than rebuild it for a small market.
