FinFETs: Novel Design Opportunities

Dept. of Electrical Engineering
The constant march of miniaturization of transistors with each new generation of bulk CMOS technology has resulted in significant improvements in digital circuit performance. Further scaling of bulk CMOS, however, faces significant challenges due to fundamental material and process technology limits, including short-channel effects, sub-threshold leakage, and device-to-device variations. It is expected that introduction of double-gate field-effect transistors, such as FinFETs, will be required to overcome these obstacles to scaling.
In this talk, we will explore the novel design opportunities from the circuit to architecture level made possible by the double-gate nature of FinFETs. Independent control of the front and back gates of FinFETs enables various new logic styles. It also makes fine-grain leakage-delay tradeoffs possible. This leads to circuits and architectures that are not feasible in bulk CMOS. We will present several examples to show how the rich FinFET design space can be exploited.
