Frequently asked questions

What is the 3D metrology tool of reference at every HBM/CoWoS player thesis about?

**Bottleneck theme:** HBM / Packaging **Focus:** $CAMT — CAMTEK LTD Camtek's 3D inspection tools are the metrology of reference at every HBM and CoWoS player. Together with $ONTO, Camtek forms the duopoly in advanced-packaging optical inspection — measuring bump height, alignment, void detection, and warpage on stacks and interposers where any defect at the 10-12µm pitch scrap range translates into thousands of dollars of lost die. The Eagle G2 / Eagle G2T platforms are sole- or co-qualified at the leading HBM stackers (Micron, SK hynix, Samsung) and at TSMC's CoWoS lines, with installed-base service revenue providing recurring, high-margin contribution. The investment case is mid-cycle compounding plus an HBM4-driven content uplift: each generation has tighter pitch, more layers, and stricter inspection requirements. The bear case is the duopoly with Onto (price competition possible), KLA's continued push into advanced-packaging metrology, and small-cap volatility versus the larger WFE peers. Pair with $ONTO for diversified HBM/CoWoS metrology exposure.
