Lisa Su

Semiconductor Physicist, Chair & CEO of AMD

Biographical Overview

Semiconductor physicist and Chair & CEO of AMD who pioneered Silicon-on-Insulator (SOI) manufacturing technology at IBM and revitalized high-performance computing with AMD's Zen microarchitecture. Su transformed modern CPU design by moving from monolithic dies to modular "chiplet" architectures that power today's top supercomputers and cloud data centers.

"To win in semiconductors, you have to place bets 3 to 5 years before anyone else sees the wave. You cannot play catch-up in silicon."

Historical Context & Impact

In short

Lisa Su wrote her MIT doctoral thesis on silicon-on-insulator technology in the early 1990s when most semiconductor experts considered it an expensive, impractical lab curiosity. Within a decade, her IBM research proved that placing insulating oxide layers beneath transistors slashed power leakages, establishing a standard that enabled multi-gigahertz processors.

Key Technical Breakthroughs & Inventions

Silicon-on-Insulator (SOI) Semiconductor Physics Formulated dielectric insulation manufacturing techniques at IBM, eliminating parasitic capacitance and allowing chips to run faster with less power.

Cell Broadband Engine Microprocessor Directed high-speed interconnect engineering for the heterogeneous multi-core Cell processor used in scientific clusters and the Sony PlayStation 3.

AMD Zen Chiplet Architecture Architected the transition to modular multi-die chiplet designs in AMD Ryzen and EPYC processors, outperforming legacy monolithic silicon scaling.

IEEE Robert N. Noyce Medal Became the first woman awarded the IEEE Robert N. Noyce Medal for seminal technical and business leadership across the semiconductor industry.
