Entegris, Inc. — AI supply-chain exposure

Entegris supplies the consumable materials and filtration that keep advanced chip fabrication clean and precise — CMP slurries that polish wafers, liquid filters that strip out contamination, specialty gases, and selective-etch chemistries. These are not the glamorous tools but the fluids and materials a fab burns through continuously. Much of its business is tied to leading-edge logic and advanced memory, the exact nodes that AI accelerators and HBM require.

Its structural hook is that revenue scales per wafer pass — the more leading-edge wafers TSMC, Samsung, and Intel run, and the more process steps each wafer takes, the more Entegris material is consumed. That makes it a recurring, consumption-based claim on advanced-node output rather than a one-off equipment sale, and finer geometries only raise the purity and filtration bar, tightening reliance on a narrow set of qualified suppliers. The model weights it for owning a low-profile but unavoidable input to every advanced wafer.
