Tokai Carbon Korea makes the solid consumable parts that line semiconductor process chambers — silicon-carbide and graphite rings, susceptors and other components that sit inside etch and epitaxy tools. These parts are sacrificial: they erode under plasma and heat and must be replaced on a schedule, making them a steady recurring input for the memory and foundry fabs it serves.
The structural point is that consumables track utilisation, not capex. When fabs run hot — as they do to feed AI demand — chamber parts wear faster and reorder more often, so Tokai Carbon Korea's pull rises with production intensity rather than with one-time equipment buys. SiC parts in particular are qualified per-process and hard to second-source, giving it a sticky place in the materials layer.
