An illustration of a 32nm transistor compared to a 22nm transistor. 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.

A “before” picture, showing 32nm transistors with the source, drain and channel (the latter covered by the gate) all in the same plane.
