An integrated circuit includes N plane-like metal layers. A first plane-like metal layer includes M contact portions that communicate with the N plane-like metal layers, respectively. The first plane-like metal layer and the N plane-like metal layers are located separate planes. First and second drain regions have a symmetric shape across at least one of horizontal and vertical centerlines. First and second gate regions have a first shape that surrounds the first and second drain regions, respectively. First and second source regions are arranged adjacent to and on one side of the first gate region, the second gate region and the connecting region. The first source region, the second source region, the first drain region and the second drain region communicate with at least two of the N plane-like metal layers.
