IBM and Samsung Say New Chip Design Could Extend Phone Battery Life to a Week

IBM and Samsung have announced a new development in semiconductor design that they report will lengthen phone battery life significantly . The companies' discovery is called Vertical Transport Field Effect Transistors -- VTFET, for short -- and is a new approach to stacking transistors vertically instead of horizontally.With VTFET, current will run in an up-and-down flow pattern, rather than side-to-side, as transistors are built perpendicular to the surface of a chip.In comparison to the FinFET...
