UMC is the world's third-largest contract chip manufacturer, focused on mature nodes (28nm and above) that are strategically important for automotive, IoT, and power management chips — sectors TSMC has deliberately de-emphasised at leading edge. US and EU government support for mature-node domestic capacity benefits UMC's global fab footprint expansion. Margins structurally lower than TSMC but less susceptible to leading-edge capex competition.
