NanoSystems: Lab to Fab

We proudly present the lecture on NanoSystems: Lab to Fab by Tathagata Srimani from Stanford University

Abstract:

This talk discusses the lab-to-fab transfer of carbon nanotubes (CNTs) for use in energy-efficient computing. Despite initial proof-of-concept NanoSystems being built with CNTs, a transfer to industrial fabs has been difficult due to material imperfections and compatibility issues with silicon fabs. The talk presents techniques to overcome these challenges, such as new CNT extraction methods, new complementary CNFETs, repurposed silicon fab infrastructure, and integration with silicon design automation tools. The efforts have resulted in successful transfers of CNFETs into Analog Devices and SkyWater Foundry, enabling monolithic three-dimensional (M3D) integration with other technologies like silicon and Resistive RAM. The new M3D technology with CNFET+RRAM has reached maturity and shows performance comparable to that of a conventional RRAM stack using Si FET access transistors. This technology can unlock substantial system-level energy-delay product benefits vs. conventional silicon-based designs. The talk concludes with a vision for future research in NanoSystems, including new co-design approaches to derive targets for future technologies from application-level needs.
