Gallery: Intel goes 3D with Tri-Gate transistors

ntIntel reveals what will power its next-generation of chips, the 3D Tri-Gate transistor. Intel says the increased performance and reduced power consumption is the future of 22nm-based devices from handhelds to cloud-based servers.

ntLarry Dignan has more about the chip that Intel claims will keep Moore’s Law rolling.

ntThis image shows the vertical fins of Intel’s revolutionary tri-gate transistors passing through the gates.

ntIntel describes this photo: “On the left side is the 32nm planar transistor in which the current (represented by the yellow dots) flows in a plane underneath the gate. On the right is the 22nm 3-D Tri-Gate transistor with current flowing on 3 sides of a vertical fin.”
