DISCO Corporation

Near-monopoly in wafer dicing, grinding, polishing

DISCO holds an estimated 70-80% global share of precision dicing (blade + laser) and back-grinding equipment, the machines that thin and singulate wafers — a step that has become critical for HBM stacking, chiplets, and advanced packaging. As die-stacking counts rise for HBM3E/HBM4 and CoWoS, DISCO's stealth-dicing and grinders are a hidden bottleneck few generic maps capture. Its consumable blades and revenue track AI-packaging demand almost directly.
