THRESHOLD ADJUSTMENT OF TRANSISTORS BY CONTROLLED S/D UNDERLAP

摘要

Roughly described, an integrated circuit device has formed on a substrate a plurality of transistors including a first subset of at least one transistor and a second subset of at least one transistor, wherein all of the transistors in the first subset have one underlap distance and all of the transistors in the second subset have a different underlap distance. The transistors in the first and second subsets preferably have different threshold voltages, and preferably realize different points on the high performance/low power tradeoff.
