DuPont de Nemours, Inc. — AI supply-chain exposure

DuPont is a US specialty-materials group; the part that matters here is its Electronics business, which supplies the consumable chemistry of chipmaking — photoresists that pattern circuits, the pads and slurries used to polish wafers flat between layers, and the advanced-packaging and thermal-interface materials that bond and cool stacked die.

These are process chemicals and gases: low value per unit, but qualified into specific process flows and hard to second-source, which is where the pricing power sits. A fab cannot swap a photoresist or a slurry without requalifying the line, so incumbency is sticky. The model keeps DuPont a peripheral but durable supplier — far from the compute itself, yet embedded in nearly every leading-edge wafer and package that ships.
