Infineon introduces three dimensions to chip in order to increase energy efficiency. The third dimension brings additional advantages: lower consumption of silicon per transistor, which translates into material and cost savings. ...
... "With an approximately 30-percent smaller footprint compared to current single-
gate technology with the same functions and performance, the new transistors had quiescent current that measured a factor of 10 less. According to the researchers' calculations, this will increase the energy efficiency and battery life of portable devices up to two times compared to the 65nm technology going into production today. For future technology nodes (32nm and beyond), this factor will increase significantly. " ...
