Researchers at Bell Labs in New Jersey say building transistors vertically rather than horizontally could be the key to making faster, denser microchips. In today’s horizontal transistors, features are etched using lithographic methods that are approaching their miniaturisation limits. But vertical transistors could be etched into the depths of a silicon wafer, allowing them to be stacked on top of each other, the researchers told the International Electron Devices Meeting in Washington DC this week. The new design also allows current to be controlled through the two faces of the transistor,
