The thesis — preview.
Lam Research owns the etch and deposition franchise that physically makes HBM through-silicon vias and 3D NAND stacks — the two highest-growth equipment lines in the cycle — and the Q3 FY26 record print plus the SK Hynix / Samsung HBM TSV capacity ramp through 2027 makes this the equipment-pair-trade alongside KLAC. Lam makes the plasma-etch tools (the Kiyo, Flex, and Versys lines for conductor and dielectric etch) and the deposition tools (Striker ALD, Vector PECVD, ALTUS tungsten CVD) that perform two specific operations in semiconductor manufacture: removing precisely-defined volumes of material from the wafer surface (etch) and laying down precisely-controlled thin films of material on the wafer surface (deposition). At leading-edge nodes these steps run hundreds of times per wafer, and the binding-constraint volume for AI memory specifically comes from two product lines.…
