Robert Tsao

Robert Tsao co-founded United Microelectronics Corporation (UMC) in 1980, pioneering Taiwan’s semiconductor foundry industry alongside Morris Chang. By 2025, UMC remained the fourth-largest foundry globally, generating $7.8 billion in revenue with a focus on mature process nodes. Tsao’s operational efficiency is cheaper than the typical rival in the 28nm and 40nm segments, offering 15% lower cost per wafer than larger competitors. While #1 Chang built TSMC into a behemoth, Tsao deliberately kept UMC lean, avoiding a race for extreme miniaturization. Beyond business, his outspoken advocacy for Taiwanese sovereignty and democracy made him a unique figure in the tech elite.
