Materials and Devices for 3D ICs
The integrated circuit (IC) was invented more than 60 years ago. We have witnessed how semiconductor technology has become vitally important to our everyday life, from servers, to PCs, and smartphones. Semiconductor technology plays a truly vital role for humanity, not only in terms of economic development, but also in the way we live, the way we work, and the way we enjoy life. Today, this vital role is manifested in the use of high-performance computing to find a cure for COVID-19, and the computing and communication technologies that enabled work from home, online teaching and learning, and online purchase and delivery of goods and services.  Future electronic systems will continue to rely on, and increasingly benefit from, the advances in semiconductor technology as they have had for more than five decades.  

Three dimensional integration is one of the major technology directions for integrated circuits. I will give an overview of the new materials and device technologies that may need to be developed to realize monolithic 3D integration with multiple logic transistor and memory device layers. I will speculate on how they will be integrated into future electronic systems and what future technologies need to be invented to realize energy-efficient 3D ICs.

About Dr. Wong
H.-S. Philip Wong is the Willard R. and Inez Kerr Bell Professor in the School of Engineering at Stanford University. He joined Stanford University as Professor of Electrical Engineering in September, 2004. From 1988 to 2004, he was with the IBM T.J. Watson Research Center. From 2018 to 2020, he was on leave from Stanford and was the Vice President of Corporate Research at TSMC, the largest semiconductor foundry in the world. Since 2020, he has been the Chief Scientist of TSMC. He is a Fellow of the IEEE and received the IEEE Electron Devices Society J.J. Ebers Award for “pioneering contributions to the scaling of silicon devices and technology.” He has held leadership positions at major multi-university research centers of the National Science Foundation and the Semiconductor Research Corporation. He is the founding Faculty Co-Director of the Stanford SystemX Alliance – an industrial affiliate program focused on building systems, and the faculty director of the Stanford Non-Volatile Memory Technology Research Initiative (NMTRI).
