Claim 15:
16. A semiconductor device comprising:
a three-dimensional (3D) stack including a plurality of transistors disposed in a first layer and a second layer, the second layer being disposed above the first layer;
the first layer including a first gate and a first channel of a first transistor and a second gate and a second channel of a second transistor, among the plurality of transistors;
the second layer including a third gate and a third channel of a third transistor and a fourth gate and a fourth channel of a fourth transistor, among the plurality of transistors; and
a first shared contact and a second shared contact,
wherein the third channel is disposed above the first channel, and is connected to the first channel by the first shared contact,
wherein the fourth channel is disposed above the second channel, and is connected to the second channel by the second shared contact, and
wherein a width of the third channel is less than a width of the first channel, and a width of the fourth channel is less than a width of the second channel.
