Integrated Circuit Having a High Cell Density

A method comprising:

• retrieving cells from a cell library, wherein retrieving the cells includes retrieving first and second cells, each of which includes
• a plurality of gate electrodes, each of the first and second cells being divided by the plurality of the gate electrodes thereof into a plurality of tracks,
• a source region,
• a contact conductive line that extends from the source region, and
• a power conductive line that is coupled to the contact conductive line and that spans across the tracks;
• and
• placing the cells at locations in a layout of an integrated circuit.
