Investors are selling $BESI, in our view, because customers increasingly prefer or consider shorter HBM stacks, since HBM is expensive. Our industry information points to customers requesting stacks of four or six memory dies. Fewer layers mean fewer connections and, where hybrid bonding is used, fewer bonding steps per stack, and shorter stacks fit package-height limits more easily with conventional solder. That could delay equipment adoption and weaken the nearer-term HBM opportunity for $BESI, which supplies hybrid-bonding equipment. Logic folding is the tailwind. It places parts of a circuit above one another on vertically connected layers joined through hybrid bonding, so signals travel shorter distances and the chip runs faster on less energy. Those benefits hold even when an inference system needs less HBM, and the layers still need aligning and connecting with exceptional precision. In our view, that can create more hybrid-bonding demand than this delay takes away. Wider folding also pushes inspection and measurement into more logic-chip applications. We expect that to lift spending faster than chip volumes for $ONTO and $CAMT, and for $NVMI, whose materials and chemistry checks address problems that get harder as circuits move into vertically connected layers. Longer term, folding could make chips on established processes more capable for $UMC. That is our prospective thesis, not an announced UMC program. Deeper dive available at Convequity.
