What does Foundry mean?

A foundry makes semiconductors to order for chip designers, especially fabless companies. TSMC is the largest; others include Samsung Foundry, GlobalFoundries, UMC and SMIC. Foundry economics are driven by very high fixed costs: a fab costs billions to build and its equipment ages fast, so profit depends on keeping utilization and yield high. Example: a fab with capacity for 100,000 wafer starts a month runs at 90 percent utilization, using 90,000. If demand drops to 70 percent, most costs stay the same while revenue falls by more than a fifth, so profit falls much further. This is operating leverage.
