Abstract
(EN)
An apparatus includes a first layer, a second layer under the first layer along an axis, and a metal layer between the first layer and the second layer along the axis. The first layer includes a first plurality of transistors, where a given transistor of the first plurality of transistors includes a gate region; and the second layer includes a second plurality of transistors. The metal layer includes a metal below the gate region, and the metal is within thirty nanometers (nm) of the gate region.
