Abstract
Extremely high density CMOS technology for 40nm low power applications is demonstrated. More than 50% power reduction is achieved as a SoC chip by aggressive shrinkage and low voltage operation of RF devices. Gate density of 2100kGate/mm 2 is realized by breaking down conventional trade-off of leakage power and performance with three key approaches. 0.195μm 2 SRAM with excellent static noise margin is also accomplished by minimizing random impurity fluctuation using Hf doped silicate as gate dielectrics. In addition, novel DFM (Design for Manufacturing) techniques are introduced for systematic yield improvement.
