Lithography Chemicals Are Becoming the Invisible Infrastructure Behind AI Chips, HBM Memory and the Next 1,000-Layer Semiconductor Story

Inside a semiconductor fab, the most expensive object may be the lithography scanner, but the most frequently repeated act is chemical patterning. A single advanced logic wafer can move through more than 60 lithography-related steps before it becomes a finished chip. Every pass needs coating, baking, exposure, development, rinsing, edge-bead removal, defect control and post-pattern cleaning....
