STRUCTURE AND METHOD OF RECTANGULAR CELL IN SEMICONDUCTOR DEVICE

A layout method includes generating a design data comprising an electronic circuit, and generating a design layout by placing a first cell corresponding to the electronic circuit. The first cell includes a first source/drain region and a second source/drain region extending in a first direction in a first layer, a gate electrode extending in a second direction perpendicular to the first direction in a second layer, and a first conductive line arranged in a third layer over the second layer and electrically connected to one of the first source/drain region, the second source/drain region and the gate electrode. The first cell is defined by a left cell side and a right cell side. At least one of the left cell side, the right cell side, the gate electrode and the first conductive line extends in a third direction not parallel to the first and second directions.
