Abstract
The semiconductor structure includes a plurality of FETs disposed on a semiconductor substrate, the FETs including gates with elongated shape oriented in a first direction; a first metal layer of first metal lines disposed over the gates and oriented in a second direction perpendicular to the first direction; a second metal layer of second metal lines disposed over the first metal layer and oriented in the first direction; and a third metal layer of third metal lines oriented in the second direction and disposed over the second metal layer. The first metal lines have a first pitch P; the second metal lines have a second pitch P; the third metal lines have a third pitch P; and the gates have a fourth pitch P, wherein a ratio of the second pitch over the fourth pitch P:Pis about 3:2.
