Intel senior fellow Mark Bohr showed off the company’s revolutionary new 3D transistors in an announcement today in San Francisco. Here’s the video where he explains how small these transistors are, how they work, and how they will lead to faster, smaller, and cheaper electronic devices in the future.
In the video, Bohr explains that these transistors are normally built in a two-dimensional fashion, where electrons flow from one end of a transistor to another in a planar way. With the Tri-Gate transistors, they flow sideways, then up, then across and then down again. This allows the transistor to take up less space on a chip, the same way a skyscraper is a more efficient use of a plot of land.
