The Road to Gate-All-Around CMOS – MIT AI Hardware Program

Despite the much debated end of Moore’s Law, CMOS scaling still maintains economic relevance with 3nm finFET SoCs already in the marketplace for over a year and 2nm gate-all around SoCs well into risk production. Modest feature size reduction and design/technology innovations co-optimized for primarily logic scaling continue to offer compelling node-to-node power, performance, area, and cost benefits. In this tutorial, we will start with a walk through memory lane, recounting a brief history of transistor evolution to motivate the migration from the planar MOSFET to the fully depleted FinFET. We will summarize the key process technology elements that have enabled the finFET CMOS nodes, highlighting the resulting device technology characteristics and challenges. This will set the context for motivating the introduction of the gate-all-around device architecture, namely nanoribbons or nanosheets, and unveiling the magic of how these devices are fabricated.
