1. A semiconductor device including a plurality of standard cells, wherein:
the plurality of standard cells include a first group of standard cells arranged in a first row extending in a row direction and a second group of standard cells arranged in a second row extending in the row direction, and a third standard cell,
the first group of standard cells and the second group of standard cells are arranged in a column direction,
a first cell height of the first group of standard cells in the column direction is different from a second cell height of the second group of standard cells, and
the third standard cell is disposed over the first row and the second row and has a cell height equal to a sum of the first cell height and the second cell height.
