Camtek — AI supply-chain exposure

Camtek builds optical inspection and metrology systems — the machines that scan wafers and packages for defects and confirm that features sit where they should. Its growth is tied specifically to HBM and to advanced, CoWoS-class packaging, where memory stacks and logic are bonded together on an interposer. Every one of those bonding steps is a place a defect can hide, so inspection becomes essential exactly where the industry's hardest manufacturing now sits. The model places it as a supplier to yield and to packaging capacity.

The structural hook is that Camtek sells picks and shovels to the tightest bottleneck in the chain. Advanced packaging is the step that currently caps how many accelerators can be finished, and yield on those lines is fragile; the tools that police it are not optional. As packaging capacity is expanded to relieve the crunch, inspection equipment is bought alongside it — giving Camtek exposure to the build-out of the very capacity everyone is racing to add.
