Semiconductor device including power mesh

A semiconductor device, comprising:

• a base having a first surface;
• source and drain electrodes and gate electrodes arranged on the first surface of the base, wherein the source and drain electrodes are arranged in an array, and the gate electrodes are extended along a first direction;
• a power mesh arranged below the first surface of the base, the power mesh comprising first power rails and second power rails, wherein the first power rails are separated from each other in a first direction and extend along a second direction, the second power rails are separated from each other in the second direction and extend along the first direction;
• first vias for coupling the first power rails to the second power rails in a third direction substantially perpendicular to the first surface of the base;
• and
• signal tracks arranged above the first surface of the base, and coupled to the source and drain electrodes through second vias, wherein at least two of the second vias are arranged in rows along the second direction.
