United Microelectronics Corporation’s moat comes from high switching costs in semiconductor manufacturing, economies of scale in mature-node and specialty-process fabs, and a strong patent portfolio that protects process know-how. Its customer stickiness is reinforced by long-term contracts and reliable, cost-effective production for non-leading-edge chips, though it lacks a major leading-edge technology moat.
