Abstract
A semiconductor device includes a plurality of standard cells. 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. The first group of standard cells and the second group of standard cells are arranged in a column direction. A cell height of the first group of standard cells in the column direction is different from a cell height of the second group of standard cells in the column direction.
Claims20
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.
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, a second group of standard cells arranged in a second row extending in the row direction, and a third group of standard cells arranged in a third row extending in the row direction,
- the first group of standard cells, the second group of standard cells and the third group of standard cells are arranged in a column direction, and
- at least two of a first cell height of the first group of standard cells in the column direction, a second cell height of the second group of standard cells in the column direction and a third cell height of the third group of standard cells in the column direction are different from each other.
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, a second group of standard cells arranged in a second row extending in the row direction, and a third group of standard cells arranged in a third row extending in the row direction,
- the first group of standard cells, the second group of standard cells and the third group of standard cells are arranged in a column direction,
- at least two of a first cell height of the first group of standard cells in the column direction, a second cell height of the second group of standard cells in the column direction and a third cell height of the third group of standard cells in the column direction are different from each other, and
- the first cell height of the first group of standard cells, the second cell height of the second group of standard cells and the third cell height of the third group of standard cells are determined based on a number of metal wirings arranged along the column direction within each of plurality of standard cells, the metal wirings being located at a level closer to a substrate than a level at which the first and second power supply wirings are located.
