Advanced packaging metrology

The incumbents got there first: KLA, Onto and Camtek already ship the hybrid-bond and glass tools, so the AI packaging boom is a public-markets story.

  • Bear
  • Closing
  • $12B by 2035

The callThe bear case is more likely, because KLA, Onto and the bonder makers already ship inspection for stacks and glass and look set to absorb about 85% of the new work. The market goes from $2.2B to $11.6B either way, with about 1.3% open.

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. D1AI chips are stacks of hybrid-bonded logic and HBM at sub-micron pitch heading onto glass panels, and wafer-era inspection cannot see inside a stack or across a panel at speed.
  2. D2KLA's packaging process-control revenue went from $635M in 2025 to a $1.0-1.1B guide for 2026, the best evidence the spend is real.
  3. R1The incumbents got there first: Applied folded overlay into its hybrid bonder with BESI in November 2025, and KLA and Onto ship hybrid-bond and glass tools.
  4. R2The startups at this layer are past entry prices, Nearfield on a $380M Series D and Invisix on a €20M seed, and EuQlid set a $50M SAFE cap.
  5. C1TSMC's CoPoS panel-level packaging enters production, and glass panels for AI packages need new overlay and inspection tools the wafer incumbents have not built.2H 2028

What changedthe record, newest first
  • 16 Jul 2026The measurement layer of advanced chipmaking keeps re-rating: this quarter saw a $380M growth round for in-line 3D metrology and a fresh ASML spin-out funded at seed for X-ray measurement of stacked devices. Once chip structures went vertical, the ability to see inside them became the scarce input.
